MOLECULAR MARKERS TO HELP WHEAT BREEDERS IMPROVE EFFICIENCY OF SELECTION FOR SPECIFIC TRAITS

 

Steve Quarrie1, Sofija Pekic Quarrie2, Boris Kobiljski3, Dejan Dodig4

 

1Beograd, Srbija,2Poljoprivredni Fakultet, Univerzitet u Beogradu, Beograd-Zemun,

Yield and quality are the two traits targeted by breeders for improvement, of which yield is probably more difficult and complex to work with. Molecular markers, particularly microsatellites (SSRs) and other PCR-based methods, are revolutionising breeding opportunities for many breeding organisations, with marker-assisted selection (MAS) becoming commonplace. Markers have also revolutionised opportunities for physiologists and agronomists to help breeders understand what processes control yield in particular environments. Thus, quantitative trait locus (QTL) analysis using molecular markers allows the underlying mechanisms determining yield to be dissected and provides opportunities to target specific regions of the genome to improve traits determining yield using MAS. Thus, a region of chromosome 7AL has been identified from our work to regulate yield in bread wheat in many environments, and QTL analysis shows this to be related with biomass productivity and particularly leaf width. Association mapping with genetic resources can identify alleles of these markers associated with wider leaves and these markers could then be used to monitor the transfer of alleles for wider leaves into breeders’ stocks. This would increase biomass production in wheat and in many environments would also lead to improved yield.

FIFTY YEARS OF WHEAT BREEDING IN SERBIA: YIELD IMPROVEMENT AND ASSOCIATED CHANGES

 

Novica Mladenov, Srbislav Denčić, Nikola Hristov, Borislav Kobiljski

 

Institut za ratarstvo i povrtarstvo, Novi Sad

 

Twenty wheat cultivars were studied to determine the contribution of breeding to wheat yield increases in the last 50 years. Chosen for the study were cultivars released in a variety of different years, each representing a different period of breeding. Only cultivars that played a major role in the wheat production of the Republic of Serbia were used. A trial lasting four years (2001-2004) was carried out in a single location using a randomized block design with three replicates. Increases in average yields of cultivars from different breeding periods were analyzed by linear regression. An increase in yield of 128 kg/cultivar (expressed as the regression coefficient) was recorded between cultivars from different periods of selection. Since the cultivars studied were released at three-to-four-year intervals, the genetic potential for yield was increased at an approximate rate of 35-45 kg/year. The cultivars tested differed significantly with respect to their morphological characteristics (plant height) as well as yield components (grain number per spike and 1,000-grain mass). In the newer cultivars, significant increases in grain number per spike and 1,000-grain mass were observed. The results of our study indicate that breeding has contributed significantly to increasing the volume of wheat production in the country.

ORGANIC PLANT BREEDING AND ORGANIC SEED PRODUCTION

 

 Janoš Berenji

 

Institut za ratarstvo i povrtarstvo Novi Sad

 

The question of variety choice along with the certified seed supply in organic production at the beginning was regulated by banning the use of treated seed produced under conventional production of conventional varieties. In the next phase the planting material produced under organic conditions was required. The ultimate goal is to replace conventional by organic varieties and to use organic seed. In organic plant breeding the importance of genetic resources (old varieties and landraces) is fully expressed. Compared with conventional, there are some restrictions as far as the choice of breeding methods in organic plant breeding are concerned. The methods for induction of genetic variability and the methods of selection permitted in organic plant breeding can be classified into three categories: permitted (interspecific cross, backcross, mass selection, individual selection, use of molecular markers, etc.), conditionally permitted (use of hybrid varieties, somatic embryogenesis, anther culture, etc.), and banned (interspecific cross, protoplast fusion, induced mutations, genetic modification, etc.). Organic seed production is characterized with a number of unique features necessary for the seed to fulfill not only the requirements for certified seed but also those for organic production. The contemporary idea for certified seed in organic production recognizes two categories: (1) seed produced under organic conditions and (2) organic seed. The purpose of the current research is to develop new solutions for seed production (especially concerning seed treatment) for organic seed in accordance with the standards of organic production.

NEW TRENDS IN MAIZE BREEDING

Demands of modern science inflict upon breeders tasks relating to creation of new high yielding maize hybrids tolerant to different stress factors in a short period of time, which has generated the need for development and implementation of modern and efficient techniques and methods in plant breeding. Breeding programs comprise development of pre-breeding material, populations with narrow and broad genetic basis, their continuous improvement, development of inbred lines and hybrid production. Different methods of recurrent selection are used for population improvement (HS, FS, HSRRS, FSRRS). The current tendency is to test newly formed combinations on the highest possible number of locations. The use of molecular biotechnology techniques makes breeding programs more efficient and cost-effective. Plant molecular biotechnology comprises molecular breeding, use of molecular markers for identification of specific genes, which control a trait of interest already present in an organism and transformation, which enables a gene from any organism to be transferred into the host plant.  A new trend in molecular breeding is the use of double haploids (DH). One of the new trends in maize breeding programs could be influenced by energetic crises, i.e. bigger needs for using of maize for production of ethanol. It is well known that different maize hybrids give different ethanol yields and the difference between the hybrids with the highest and the lowest ethanol yields is 6%.

Breeding and production of plants were based on existing limited knowledge and capacity of human and natural resources and modern requirements of consumers. Permanently are developing cultivars and hybrids with high adaptability, with enhanced quality and high yield in preferable and unfavorable conditions.  On the base of those two concepts were created numerous cultivars and hybrids resistant to biotic (diseases and pests) and abiotic stress factors  (frost, drought, salinity). Within concepts og genotypes, traits and genes by applying methods of hybridization, polyploydization, induced mutation and modern biotechnological  methods, were developed cultivars with desirable combination of genes and traits. For each plant species in breeding there are specific requirements aiming profit on the base of high and stable yield, enhanced nutritive quality. Also, concept of biofarming and biofortification was developed in which plants is a bioreactor in production of medicine as well synthesis of amino acids,  mineral elements, vitamins and antioxidants. Importance of biotechnological methods are in: decreasing of breeding process, increasing of genetic polymorphysms, efficiency  of genotype identification and increasing of productivity of of wheat, soyabean, maize, rice and other plants.

In sugar beet hybridization multigerm diploid populations or families are of special importance, since they are used as pollinators for development of F1 hybrids, or donors of desirable genes for important quantitative and qualitative traits. Existing genetic polymorphism inside populations and between them is necessary for increasing genetic potential for yield and resistance to important diseases, like rhizomania. In presented research were used three populations of narrow genetic base, with 10 S1 families from each of them. Populations differed in important quantitative traits, but had the same type of resistance to rhizomania (Rz1). By applying suitable statistical analysis, the genetic divergence was confirmed between both, populations and their S1 families, not just in quantitative traits but in combining abilities as well.

The main objective of the sunflower breeding program in Novi Sad  is to create hybrids with high seed yeald genetical potenitial above 5t/ha (Miklič et. al., 2008). Establishing the interdependence of qualitative traits with weight of 1,000 seeds enables a better usage of genetic resources in breeding on a high genetic potential of sunflower seed yield. In this research we used 21 experimental hybrids created at the Institute of Field and Vegetable Crops in Novi Sad. The hybrids include new divergent (A) cms imbreed lines crated by interspecies hybridization. The experiment was set at an experimental field of the Institute of Field and Vegetable Crops at Rimski Sančevi, in a randomized complete block system with three replications, during the period of two vegetation seasons. The basic sample for analysis of the examined trait consisted of thirty plants. Among the examened sunflower genotypes significant differences in .middle value were found for all examened traits. A strong positive correlation was determined between the weight of 1,000 seeds and total head diameter per plant (0.461**). An important positive correlation was determened between precnika stabla(0.379*)and head diametar (0.291*) with weight of 1,000 seeds. The results could be used in the sunflower breeding program.

In Stara Planina region, area Radičevac, the most important biological and pomological characteristics of dogwood (Cornus mas L.), on randomly selected sample of 30 genotypes, were examined in aim to recognize biological diversity of this population. Examinations were done in 2004 and 2005. Experiment included the most important properties of vegetative and generative organs such as tree, fruit branches and flowers. The most important economical and pomological fruit properties studied in these investigations were fruit weight, fruit size, output, fruit quality and yielding. By analyzing obtained results can be concluded that tree vigour ranged from 3.2 up to 8.5 m, with predominant part of genotypes that were higher than 6m. Trunk circumference was from 10 to 87 cm, and number of basal branches was 1-4. Length of fruit branches varied from 9.5-35 cm, and number of buds per branch was 4-17. Number of flowers in inflorescence was 4-37, and number of stamens per flower varied from 2 to 4. All flowers in examined genotypes had only one pistil, while flower stalk ranged from 4.1 up to 6.9 cm. Fruit weight was from 1.10 to 2.42 g, and stone weight from 0.20 to 0.42 g, that resulted in output variation from 70.0 to 85.1%. Total soluble solid content was 13.5-24.5%. Yielding was determined by pointing from 1 to 5, and was averagely around 3.4, but with predominant part of genotypes with medium yields (lower than 3 points).

Breeding is an activity that requires not only long-term financial investments, but also genetic and human resources. The protection of breeder's rights enables a reliable exclusive right which will improve chances in the protection of intellectual properties within this field and by it a chance for the accumulation of the necessary funds for further investments within this field will be increased. With the aim of this protection, UPOV established the detailed instructions for the conduct of DUS tests for more than 170 plant species. Errors are always possible throughout testing. Human factor is in the basis of each error, but there are also many other reasons that cause errors. In the course of phenotypic characterisation of maize genotypes in compliance with the principles of the UPOV Descriptor, the spreadsheet method was used for the identification of possible incorrectnesses and several characteristic cases of incorrect evaluations were observed.Permanent control and validation of obtained estimates are important. Due to neglectful attitude errors occur, so the tested variety can be proclaimed identical, when, in fact, it is different and vice verse, could be proclaimed different when it is actually identical. Certainly, the crop expert experience in biology of a certain plant species, as well as, the existence of a high quality reference collection, check genotypes, appropriate computer softwares and data bases are of a great importance in order not to avoid making wrong decisions.

The following four traits in seven population of sage (Salvia officinalis L.) were observed: plant height (cm), herb yield (g), leaf yield (g) and essential oil content (%). Significant differences of their values, i.e. great variability of traits among observed populations were determined. The degree of their divergence was estimated by hierarchical cluster analysis. Three cluster, i.e. three varietal groups of different pfenotypic properties were observed on a dendogram. Linking genotypes into the same groups was primarily in function of their yield, and therefore varietal similarity within groups on the basis of values their other traits. Information about forms of divergence of these genotypes is important in sage breeding and hybridisation planning.

USE OF HALF-SIB AND FULL-SIB SELECTION IN RED CLOVER

 (Trifolium pratense L) BREEDING

Red clover (Trifolium pratense L) is a markedly open pollinated species with a pronounced mechanism of gametophytic self-incompatibility, which prevents the development of inbred lines because of the presence of homozygous S-alleles necessary for controlled crossing. For this reason, full-sib selection is not widely used in red clover breeding, except in cases of parental pairs possessing high SCA values for certain traits or in cases when the goal is to incorporate into a high-yielding variety a particular desirable  agronomic trait such as resistance to a disease, longer plant life, or overwintering ability.Half-sib selection is most often utilized in red clover breeding by means of the least expensive and most efficient breeding methods (mass selection, recurrent phenotypic selection). This type of selection is based on GCA and is highly dependant on the presence of superior genotypes and additional knowledge of the degree of heritability of the traits targetted by the selection. The use of diallel crosses provides more complete information on the GCA, SCA, mode of inheritance, and heritability of the traits concerned. It is especially important to note that progeny tests using diallel crosses may be used to determine the direction of future work on red clover breeding.Over a four-year period (1999-2002), progeny tests were done on dialel hybrids of red clover and traits were selected for whose inheritance additive gene action  was found (stem length, fresh weight yield per plant, growth habit, hairiness).

Centar za strna žita-Kragujevac, Kragujevac

 

Introduction of new cultivars, ours and world production of spring oat have been grown. The most important problem of out creation and selection is resistance to diseases. Diseases are cause of 12% loses from total world,s production of this culture (Janjić et al., 1995). There are many different possibility for out protection against diseases. Among integral protection measures resistant cultivars creation and growing has primary importance of oat protection against causes of leaf rust. During 2002, 2003. and 2004. there was a study of spring outs in phase of adult plants in a field to Puccinia coronata avenae in conditions of artificial inoculations at experiment field in Center for small grains in Kragujevac. Plant inoculation was performed several times beginning with the phase 23 BBC- scale in evening hours by sprinkling plants with suspensions uredospore pathogen. The infection types were determinate with the method (Stakman et al., 1962.). The infection coefficients were calculated according to the formula (Levine and Basile, 1959).

On the basis of the data presented can bee the conclusion that there were not highly resistant and highly susceptible cultivars. The cultivar F. Nova shown resistance with infection coefficient of 10%, while the four cultivars (Boris, Fagot, Tlama and Blanko) were medium resistant with infection coefficient from 15 to 25%. The greatest number of cultivars were intermediary (38,88%). In category of resistant types there were 49,99%, 22,22% of that were resistant and 27,77% were medium resistant, still highly resistant and highly susceptible were not found. In category of medium susceptible cultivars were 11,11%.

The Institute PKB Agroekonomik was established in 1961 as an expression of developing and researching needs of the PKB Entreprise, one of the biggest agricultural corporations of the state time. Since its beginning till present days the Institute PKB Agroekonomik has passed through the different organiyational and technological transformation, but the essence of work and existing was always the same: to improve the agricultural production over the modern scientific bases and through the breeding of new cultivars and selections, as well as the technology transfer to other agricultural companies. One of the basic activities at the Institute, i.e. the Farming and Vegetable Research Station, is the breeding of new winter wheat cultivars. Since 1979, when the firs winter wheat cultivar (PKB Krupna) was introduced, till 2007 the State Commission for recognition has accepted 20 new Institutes winter wheat cultivars. Good adaptability, along with the enviable level of seed yield and technological quality of the flour are the traits because of which the PKB winter wheat cultivars have found their place in the production in our countru, as well as in the neighboring states, since 1979 of the last century till today.

Institut za voćarstvo, Čačak

 

About 60 institutions worldwide are currently engaged in breeding new apple cultivars with superior biological and economical properties. This is a long-term process with quite uncertain outcome as apple is a deciduous, perennial, wooden and cross-pollinated species with the long juvenile period. Fruit Research Institute has a long tradition of breeding new apple cultivars. More than 110,000 hybrid apple seedlings have been developed by the planned hybridization so far. Over the most recent period, besides improvement in fruit quality and resistence to causal agents of diseases and pests, the requirements regarding maintenance of fruits in cold storage aimed at improvement thereof have been greatly pronounced.The paper presents four promising apple selections (J/12/51, J/13/41, J/3/47 and J/14/1) developed at Fruit Research Institute, mother component being cv Melrose. The analysed selections have resulted in the following crosses: Melrose x Golden Delicious (J/12/51 i J/13/41), Melrose x Čadel (J/3/47) and Melrose x Prima (J/14/1). Some phenological properties (phenophase of flowering and ripening), pomological properties (physical and chemical properties of fruit) and cropping have been assessed. The study of quality and yield of the assessed selections has shown great difference among the selections. The highest fruit weight  and total dry matter content was found in the selection J/3/47. Prounounced yields have been reported in selections J/12/51 and J/13/41.

            Breeding field pea in Serbia has begun in the last three decades in the Institute of Field and Vegetable Crops in Novi Sad. The introduction of genes controlling early maturity, short internodes, determinate stem growth and the development of new leaf types, such as normal leaf type with narrow leaflets or afila leaf type with all leaflets reduced into tendrils, led to the development of new field pea cultivars with high, quality and stable grain yields. The first Serbian typical field pea cultivars, Jezero and Javor, played an exceptionally important role in a wide distribution of this pea agronomic type not only in Serbia, but in its near and far neighbourhood as well. A further progress in the field pea breeding programme led to the development of the lines L-536, L-537 and L-538, that, in two-year preliminary trials, produced average grain yields of about 5000 kg ha-1, what was significantly higher in comparison to the control cultivars Jezero and Javor. During 2006 and 2007, these three lines were included in the official state trials, were characterised by a significantly more prominent earliness and significantly higher grain yields in comparison to the control cultivar, and, as a result of the former, were registered under the names of Partner, Kristal and Dukat.

CORRELATIONS OF MORPHOLOGICAL AND AGRONOMIC TRAITS OF LUCERNE (Medicago sativa L.)

 

Dragan Milić, Slobodan Katić, Vojislav Mihailović, Aleksandar Mikić

 

Institut za ratarstvo i povrtarstvo, Novi Sad

 

            During the 2001-2003 period, a collection of 30 lucerne genotypes of different geographic origin was studied  over seven cuts at the Rimski Šančevi site. The collection was planted in 2001 by broadcast sowing into 0.8 x 0.5 m hills. Seven agronomically and morphologically important quantitative traits of lucerne were studied: yields of green forage and dry matter, number of shoots (stems) per plant, internode number and length, proportion of leaves in yield, and stem diameter. The simple correlation coefficients between green forage yield and dry matter yield were highly significant (r=0.98), so there was almost functional dependence in evidence. Significant positive correlations were obtained between green forage yield and shoot number (r=0.78) and dry matter yield and shoot number (r=0.71). Highly significant positive coefficients of correlation were found between plant height and internode length (r=0.82), which is indicative of the agronomic importance of these traits. There was a medium high correlation between stem diameter and internode length (r= 0.55) Highly significant negative correlations were observed between leaf proportion in yield and plant height and internode length (r=-0.83). Green forage and dry matter yields were negatively correlated with the leaf proportion (r=-0.54 and r= -0.53, respectively). Significant positive correlations was observed among green forage and dry matter yields, plant height, shoot number, and internode length. By contrast, leaf proportion in yield and yields, plant height, and internode length were negatively correlated.

The some large differences by infection severity in field inside groups identical according to in greenhouse estimated LR index = latency period (0,7-1) x infection efficiency (6-10) x reaction type (6-10). Visual estimation of leaf senescence in field involvement also did not ensured the  strong and stable correlation. From mentioned reasons on seedlings grown at 15-20oC in greenhouse, ten days after inoculation with Puccinia triticina, length of first, second leaf and stalk were estimated. The sum of stalk and first leaf was divided with second one to get the ST and with infection STZ values. Six genotypes created in the Institute of field and vegetable crops , Novi Sad, was tested. According to the results of field parasite severities during last five years, the formula for the maximal ones under rainfall around 600 mm was established: MILR=  IFxLPxRT/(1,35-ST)x2 + 1,35. ST-STZ of variety Rapsodia was 0,70-1,14 (1,35-1,34 Novosadska rana 2, 1,26-1,44 Pobeda) to 1,55-1,60 of NS 40S. Appearance of the lower reaction types and such discussable infection efficiency connected with STZ under the 1,35 at seedling stage, could be avoided by removing the second leafs or by growing on lower temperatures.

In 1993, the Maize Research Institute, Zemun Polje, supported by the Ministry of Agriculture of the Republic of Kazakhstan, started the programme on the development of common maize hybrids (KAZ-ZP) of a high genetic potential of yielding and high quality grain. The following seven medium, medium late and late maturity hybrids were developed and then released by the Kazakh Commission for the Variety Releasing: Altaj 319 (FAO 300), Marko 419 (FAO 400), Tulpar 539 (FAO 500), Arman 689  and Skif 619 (FAO 600), as well as,  Altin 739 and Sunkar 779 (FAO 700). An annual hybrid seed production based on sterility amounts to 800-1000 tons. Furthermore, SPK "Budan", as an elite seed company, a main partner of the Maize Research Institute, Zemun Polje, regarding maize breeding and seed production, has been producing sufficient amounts of basic seed of these hybrids (parental forms) for the seed commercial production since 2006, and for that reason there is no need anymore to import the seed of parental forms. The following hybrids are tested in trials of the Kazakh Commission for the Variety Releasing: KAZ-ZP 111, KAZ-ZP 110, KAZ-ZP 210, KAZ-ZP 200, KAZ-ZP 309, Altaj 329, Kojsar 429, KAZ-ZP 499, KAZ-ZP 509, Rahat 579, KAZ-ZP 600, KAZ-ZP 629, KAZ-ZP 690, Tarlan 629, KAZ-ZP 700 and KAZ-ZP 777. For the last 3-4 years a special attention has been paid to the development of maize early maturity hybrids (FAO 100-200) intended for the northern regions of Kazakhstan.

GERMPLASM OF STONE FRUIT SPECIES – THE BASIS FOR VEGETATIVE ROOTSTOCK BREEDING

 

Gorica Paunović, Milomirka Madić

 

Agronomski fakultet Čačak

 

Fruit breeding success can be achieved by securing as many different genotypes as possible. Investigation of autochthonous fruit varieties is an initial step towards the creation of the basis for their breeding. Germplasm preservation should open up possibilities for developing new genotypes of varieties and fruit tree rootstocks. Substantial genetic resources for this type of breeding can be primarily derived from the germplasm of autochthonous and polycultural varieties of stone fruit species associated with traditional fruit growing. As Serbia has a rich pool of local varieties and stone fruit genotypes, it can be assumed that the wealth of the material can be used in developing quality vegetative rootstocks. Breeding of different-vigour vegetative rootstocks is an essential prerequisite for the intensification and improvement of plum, apricot, peach, sweet and sour cherry production in our country. Having in mind the abundance of local varieties and genotypes of these fruit species in our country, the creation of vegetative rootstocks from this material is considered both a challenge to science and an obligation of our country as one of the world’s greatest plum producers. A particular focus should be given to breeding polyvalent vegetative rootstocks, i. e. rootstocks for many fruit species. The possibility of breeding vegetative rootstocks for stone fruit species from the autochthonous genetic material has been studied in four species of the genus Prunus, being as follows: P. domestica L., P. cerasifera Ehrh., P. spinosa L. and P. institia L.

Maize is the most important crop for Serbian economy. The necessity to maintain crop genetic variability was conceived in the 50-ies of the last century, when programs for genetic resources maintenance started to develop parallel with breeding programs. Genebanks were established, with two main purposes: biodiversity maintenance of species and characterization and evaluation of genotypes for adequate use of genetic resources in breeding. Genebank of Maize Research Institute “Zemun Polje“ Gene bank maintains a huge collection of 2217 genotypes of local landraces collected from all agro-ecological sites of the former Yugoslavia, sorted according to morphological traits, origin and evolution into 18 agro-ecological groups, as well as a collection of 3602 introduced genotypes from 40 different countries. Maize breeding of today, as well as in the near future, depends upon traits maintained within existing germplasm.The material,  maintained in the Maize Research Institute “Zemun Polje“ Genebank offers the great opportunities for breeding, considering its size, content and the fact that this material has been largely described, classified and documented. In this paper some aspects of maintenance and utilization of this genetic material in breeding will be presented.

Institut za ratarstvo i povrtarstvo Novi Sad

 

In this study we analyzed 9 multigerm genotypes of sugar beet from collection of Department of sugar beet, Institute of Field and Vegetable Crops, Novi Sad.  Genotypes were chosen according to different ancesstry and uniformity of plants. The following characteristics were evaluated: root roughness, tolerance to Cercospora and high temperature, root mass and volume, dry matter content and mass of root head. Also the following correlation coefficients were estimated: between root mass and dry matter content, root mass and root head mass, between root head mass and dry matter content. Genotype 2 had the least root roughness. The highest tolerance to Cercospora and high temperature were noticed by genotype number 7. The least root mass was recorded in genotype 6. Dry matter content was the highest in genotype 3 and it was 21.77%. These characteristics will help to determinate genotypes with preferred attributes which will be later used for further crossings, in order to create improved sugar beet lines. Testing of these genotypes will be continued in 2008 year when they will be in a seed generation.

Institut za ratarstvo i povrtarstvo Novi Sad

 

Extensograph energy is one of the indicators of wheat technological quality.  It is a cultivar-specific trait that is also largely dependent on environmental conditions. Reduced extensograph energy is indicative of increased proteolytic activity and degradation of protein chains. The tendency of dough to spread, narrow fermentation tolerance, and small baking volume are all directly caused by insufficient extensograph energy. The present study analyzed extensograph energy in 20 domestic cultivars of winter wheat over three years (1998-2000) in five locations (Novi Sad, Inđija, Sremska Mitrovica, Kragujevac, and Žitorađa). The highest average energy value was found in the cultivar NSR-5 and the lowest in the cultivar Bistrica. Highly significant differences were found among the cultivars, years and locations. To analyze genotype x environment interactions, the AMMI model was used. The AMMI analysis revealed significant differences among the cultivars in the main effects and, to a much lesser degree, the interaction.  The most stable among the cultivars with an above-average energy value was Tera, while the cultivar Pesma had satisfactory stability and a high average value of the trait analyzed. Of the five trial sites, the one at Kragujevac had the highest overall cultivar stability for the trait concerned thanks to favorable growing conditions. The Žitorađa site, on the other hand, proved unfavorable for the expression of the studied trait.

Institut za kukuruz „Zemun Polje“, Beograd - Zemun, Srbija

 

Cycloxydim-Tolerant Maize, CTM was developed at the University of Minnesota in 1990, through selection in tissue culture. The goal of this study was to investigate the influence of the number of alleles of CTM genes on the level of maize genotypes tolerance to cycloxydim (Focus Ultra preparation).Four variants (V) of hybrid combination ZPL1 x ZPL2 (V1- female CTM, V2- both parents CTM, V3- male CTM and V4- neither parent CTM), were included into a randomized complete block (RCB) split-plot experimental design with three replications at two locations in 2007. Five rates of Focus Ultra preparation were applied (2, 4, 6, 8 and 10 l∙ha-1) and control without treatment. The variant V4 was not treated with the preparation, and three variants were treated in the 7-leaf stage. The grain yield and yield components were observed in this study. The highest grain yield showed variant of hybrid V4 (15,665 t∙ha-1), and then V2 with all applied doses, 14,814 t∙ha-1. With the preparation dose increasing over 4 l∙ha-1, the grain yield of V1 and V3 variants of hybrid were reduced. There was not significant yield variation of V, depending on the preparation dose.

Biljana Gorjanović i Marija Kraljević-Balalić

 

Poljoprivredni fakultet, Novi Sad

 

Nitrogen harvest index (the ratio of grain nitrogen content over total nitrogen content) is a measure of the efficiency of nitrogen translocation from the vegetative portions of the plant to the grain, and it can be recomended as selection criteria for improvement of nitrogen use efficiency. The goal of this paper is to investigate nitrogen harvest index of twelve bread wheat genotypes, on three nitrogen levels, and to classify genotypes according their phenotypic similarity for examined trait. This trait was mostly under influence of the year of investigation (52%), genotype (17.4%), and in the smallest amount of the genotype x year interaction (7,45%) and nitrogen rate (2,42%). Values for nitrogen harvest index were highest in 2005, and a smallest in 2007. The highest nitrogen harvest index were found in the cultivars Pobeda, on the N0 rate, and Zlatka, on the N100 rate (0,93), and the lowest in the cultivar Tamaro, on the N0 rate (0,63). By analyzing dendogram, it can be concluded that the genotypes Pobeda and Renan were singled out on all three nitrogen levels as the genotipes with the highest values, while a variety Tamaro was singled out as a variety with the smolest value.

CURRENTLY GROWN NS WHEAT VARIETIES AS RAW MATERIAL FOR FOOD PROCESSING INDUSTRY

 

Veselinka Đurić, Novica Mladenov, Nikola Hristov, Marija Racić

 

Institut za ratarstvo i povrtarstvo, Novi Sad

 

The paper presents the yield performance and parameters of technological quality for 10 NS wheat varieties grown in the period 2000 – 2005. Yield performance, protein content and rheological properties were affected by weather conditions, especially by unfavorable distributions of temperature and rainfall. The high five-year average yield (7.00 t/ha) and protein content (13.3%) showed that weather conditions were favorable during the stages of yield and grain protein formation. The year of 2001 was least favorable for protein content (11.8%) and sedimentation value (32 ml). The outstandingly dry year of 2003 was most favorable for these parameters, yielding the respective values of 14.6% and 42 ml. The studied varieties were also analyzed for bread making performance, as delineated by direct baking indicators. The crumb value, as a sum expression of wheat quality, varied between 4.7 (2001) to 5,9 (2005).

This paper deals with the investigation of F3 population 2002-30, created in the Department of Maize, Institute of Field and Vegetable Crops, Novi Sad. During the first year (2004), about 150 plants of the studied population were selfed and simultaneously crossed with the tester 1491x1496, in order to get complementary S1 and HS progenies. After the harvest, 41 progenies of each type were selected for the trials, by the random sample method. During the second and third year (2005 i 2006), the trials were carried out in Aleksinac, Leskovac, and Kruševac, as three studied environments, in RCB design.Genetic variances were higher in S1 progenies, with the exception of root an stalk lodged plants percent and grain number per row. Phenotypic variances followed the same tendency. The obtained values of broad-sense heritability were significantly higher in S1 than in HS progenies. Low heritability values were calculated only for root an stalk lodged plants percent. Significant, positive correlation coefficients between grain yield and the most of studied traits were calculated in both investigated progeny types. Between certain yield components negative correlation coefficients were found.

The classification of germplasm of popping maize into heterotic groups, as well as, evaluation of genetic diversity among and within existing heterotic groups are of importance for a successful popping maize breeding programme. Combining abilities of six popping maize inbred lines were tested in this study by the method of a diallel analysis. The mode of inheritance of grain yield, kernel row number, kernel number in 10 g and popping volume was determined. The rank correlation was estimated for the two most important traits, i.e. for grain yield and popping volume, in order to reveal the concurrence intensity among obtained ranks of parental inbreds for these traits in two tested locations. The relatedness and classification of observed popping maize inbred lines were evaluated by the application of protein and molecular genetic markers (RAPD method). The objective of this study was to determine whether there was and to what extend there was a congruence of data obtained by the diallel analysis and results obtained by the analysis of genome polymorphism of observed popping maize inbred lines and whether combining abilities and heterosis could be anticipated on the basis of polymorphism of biochemical and molecular markers.

Yield increase in new two-rowed barley cultivars is dependent equally on both biomass increase and harvest index improvement, whereas grain yield increase in multiple-rowed barley is more dependent on harvest index improvement. Diallel crossing of five two-rowed barley cultivars was conducted in order to examine mode of inheritance, gene effect and combining abilities of parents, resulting in the obtainment of ten F1 and F2 hybrids. There were significant differences in mean harvest index values between the cultivars studied and their progenies in the F1 and F2 generations. The lowest mean value was recorded with the cultivar SLADORAN, as opposed to the cultivar JAGODINAC having the highest value. The modes of inheritance for the harvest index in the F1 and F2 generations included partial dominance, dominance or superdominance. The variances for the general (GCA) and specific (SCA) combining abilities in the F1 and F2 generations were highly significant, suggesting that the harvest index in these researches was induced by genes with additive and non-additive, i. e. dominant effects. The GCA variance was determined to be higher in the F1 and F2 generations as compared to the SCA variance, pointing to the prevalence of the additive gene effect for the trait studied.The VADA x SLADORAN combination being the best one. Cultivars VADA and JAGODINAC were the best general harvest index combiners. They can be used in barley breeding programmes aimed at obtaining increased harvest index.

Institiut za povrtarstvo, Smederevska Palanka

 

Tomato fruit firmness is a polygenetic trait and depends on firmness components pericarp thickness, firmness of epidermis and firmness of flash). The accumulation of favourable traits ratio for each component (towards the increase of expression) the fruit firmness can be increased. This paper deals with aspects of increasing fruit firmness by increasing firmness of epidermis and thickness of pericarp. By using genotypes with rin (ripening inhibitor) gene, we were able to accomplish great firmness of fruits, especially firmness of flash. The expression of these traits cause the asynchronization of maturing process so the fruits do not over mature or soften. Genetic effects have been evaluated by researching the average values of fruit firmness in six diallel parent lines (D-150, S-49, S-35, H-52, Kg-z and SP-109) and progeny (P1, P2, F1, F2, BC1 and BC2) by applying additive dominant model with three and six parameters (Mather and Jinks, 1982). Mean values of fruit firmness for parents and progeny were significantly different. Firmness of fruits is a trait influenced first of all by additive gene since they were found in all researched combinations. Epystatic gene effect was important in inheriting process for all three two-gene interactions. The stabile duplicate type of epystsase was found, which in this case reduces the unfavourable effects of dominant genes of parents with soft fruits.

            Canada remains the leading country in the world in field pea production, while the cultivation of field pea in Serbia, where it became known as protein pea, is rather recent. The Canadian varieties of earlier generations, such as Tara and Century, played an important role in the establishment of the first Serbian field pea breeding programme in the Institute of Field  and  Vegetable Crops in Novi Sad. A small-plot trial was carried out at the Rimski Šančevi Experiment Field of the Institute of Field and Vegetable Crops during 2007. It included eighteen field pea varieties in total, with nine from Canada, eight from Serbia  and on from the  Republic of Srpska.  The joint evaluation of Canadian and Serbian field pea varieties included the evaluation of physiological parameters, grain yield components and grain yield per plot of 4 m-2. The highest grain yields were in the Canadian variety Handel  (1900 g plot-1) and the Serbian varieties Partner  (1850 g plot-1)  and  Kristal (1840 g plot-1),  while  the lowest grain yield was in the Serbian variety NS-Lim (915 g plot-1).

Resistance of 20 Serbian winter wheat cultivars in the conditions of natural infection was evaluated at Leposavić during 2005 and 2006. The studied cultivars seed was sown in consecutive rows, with row lenght of 1m and inter-row distance of 30cm. Estimation of the studied cultivars resistance was done in the stage of pathogene full development, by determining infection type (0-4) and infection intensity (0-100%). On the base of the obtained infection type and intensity values, infection coefficient was calculated. The results show the average attack intensity of 11.17% in 2005, and of 6.42% in 2006, which points to better conditions for the infection in the first year. These values is relatively low, and they are consequences not only of cultivars resistance, but also of climatic conditions and pathogene pathotypes virulence. The highest level of resistance to Blumeria graminis tritici was shown by cultivars Milica, Rodna, and Danica in 2005, and by Lasta, Srbijanka, Fortuna, Milica, Proteinka, and Danica in 2006. Renesansa was the most sensitive cultivars, with intesity of  infection  was 50% during 2005. and 30% in 2006.

Institut za ratarstvo i povrtarstvo, Novi Sad

 

In addition to high genetic yield potential, yield stability under a variety of environmental conditions is another important characteristic of new soybean cultivars. Recently released cultivars were tested for yield performance in four locations characteristic for the main soybean-growing regions of Serbia, Sombor, Sremska Mitrovica, Rimski Šančevi and Pančevo. Tests were conducted in two very different years. 2006 was exceptionally favorable for soybean production while 2007 was extremely unfavorable. Mima, a cultivar from the 2nd maturity group, had best performances on average for all locations and in both years. Mima also exhibited high yield stability under various environmental conditions, indicating that this cultivar warrants a safe production even in unfavorable years.

In addition to cultivar, soybean yield depends to a large measure on environmental factors. The interaction cultivar * location is therefore crucial for the realization of yield potential. To assess 14 new soybean cultivars from different maturity groups and to compare them against the standard ones, trials were organized in 2006 and 2007 in 21 locations. The locations were selected in the Vojvodina Province and along the Drina River, as best representatives of regions in which soybeans are grown commercially. The analysis of adaptability and stability of genotypes (Eberhart and Russell, 1966) indicated that the regression coefficient b was not significantly different from unity in either of the tested cultivars. The cultivars Sava, Tea, Venera, Valjevka and Zvezda had average yields above the average for the trial in both years. Significant differences in yield were registered among the locations as well as between the years. The uniformity of average yields of the cultivars and the significant differences among the locations are indications that the genetic yield potentials of the cultivars are not fully exploited. The cluster analysis indicated the locations of Rimski Šančevi, Pančevo, Karavukovo, Zrenjanin, Bosut and Loznica asconvenient for trial performance.

In accordance with the 2005 Seed Law, Ministry of Agriculture, Forestry and Water Management, i.e., its Department for Variety Approval and Protection is in charge of variety approval. For a variety to be officially approved, it needs to pass the DUS test, i.e., it has to be distinct from other varieties, uniform and stable. SC Agroinstitut from Sombor was tasked by the Ministry with the technical realization of the DUS test. To be able to carry out the task, Agroinstitut undertook preparations that involved personnel training, equipping of laboratories, visits to similar facilities abroad, etc. First DUS trials at the experiment field of SC Agroinstitut were carried out in 2006. They included a total of 239 varieties, 193 varieties of field crops, 26 varieties of vegetable crops and 20 varieties of forage crops. In 2007, the trials included 453 varieties, 368, 52 and 39, respectively. The trials were performed in accordance with UPOV guidelines for DUS testing of particular plant species.

The estimation of variability of six maize inbred lines and their hybrids related to the yield, superior-parent heterosis and general and specific combining abilities after the method developed by Griffing, 1956a, was the aim of this study. Since the depression of the yield occurs in inbreds in inbreeding, this trait was greater in hybrids than inbreds, as expected. The highest average heterosis for the yield was determined in the hybrid B 14 x B 37 (209..80% ). The analysis of variance of combining abilities for the yield pointed out to highly significantly positive values of GCA and SCA for the observed trait in both years of investigation. Non-additive genes (dominance and epistasis) had the significant importance for yield heritability, indicating that the significant of values of GCA and SCA. The inbreds ZPL1 and ZPL2 were lines with the highest GCA effects, while hybrid combinations ZPL2 x B73ZPL1 x ZPL2, ZPL1 x B90, ZPL1 x B91, ZPL1 x B99, ZPL2 x B90 and ZPL2 x B91 were populations with significant SCA effects in both years of investigation. They encompass both parents with high GCA effects or one parent with high GCA effects and other with low GCA effects. Furthermore, hybrid combination B 14 x B 37 had significant SCA effect and parents with low GCA effects. This is probably a result of additive gene effects (additive x additive) of the interaction between parents.

Sugar content in onion bulb is one of the most important quality trait of onion. Chemical structure of onion depends on variety and production process. In order to research the content of total sugar content in onion bulbs, a two-year experiment has been set at the Institute for Vegetable Crops in Smederevska Palanka. The experiment has been set in random blocks with five repetitions with ten varieties of onion from a different geographical origin. The values of the researched traits were processed by using two-factorial analysis – model 2 (Hadzivukovic, 1991). Components of phenotypic variance, genotypic and phenotypic variation coefficient and heritability in broader sense were counted according to Singh and Chaudhary (1976). The results proved the significant variability of total sugar content in onion bulbs in both years of research. This research proved higher genotypic variance and coefficient of phenotypic variation comparing to ecological variation and coefficient of genotypic variation. The results point to high share of genetic factors in inheriting this trait, which proves high value of heritability in broader sense (0.89 and 0.90%).

Genotype and environmental conditions determine the growth and development of small grains. The objective of this study was to assess specific features of growth and development of small grains in the 2006/07 growing season. Trials included three cultivars of each early, medium early and late winter wheat, winter barley and winter triticale. The examined features were compared against those from the 2004/05 season. In the early March 2007, the tested cultivars had 3 to 5 leaves more and they were in 2 to 3 stages of organogenesis later compared with the 2005 data. U 2006/07, vernalization was completed normally and the 2nd, 3rd and 4th stages of organogenesis were 2-4 weeks earlier than in 2004/05. A long tillering period in 2006/07 allowed the formation of large vegetative bulk, large numbers of spikes and spikelets, thus creating favorable conditions for high yield potential. The period of grain filling was longer for wheat and barley and shorter for triticale in 2007 than in 2005. The early wheat had a higher yield by 13% and the medium early and late wheat had lower yields by 31 and 29%, respectively, in 2007 than in 2005. The yield of barley was lower by 24-43% and the yield of triticale was lower by 6-20% in 2007 than in 2005. The late cultivars of all small grains had a larger yield reduction than the early cultivars. The low yields obtained in 2007 were due to the drought, which caused the drying of secondary tillers, pollen abortiveness, poor pollination and a low harvest index. In the case of winter barley, the earlier flowering made room for frost damage. Winter triticale was most tolerant and winter barley was most sensitive to the environmental conditions in the 2006/07 growing season.

SC Agroinstitut from Sombor has launched a pilot project titled "How to save and protect the old vegetable cultivars from Vojvodina" on the territory of West Bačka County. The intention of the project is to identify and multiply the collected genetic materials in order to save from extinction many vegetable cultivars and populations. During a long gardening practice, generations of growers had amassed diverse genetic materials in their gardens. Valuable vegetable populations and cultivars had been developed in the Vojvodina Province by spontaneous crossing and natural selection as well as by careful farmers' selection. Today, however, a limited number of highly profitable cultivars dominate the production. The old cultivars, although commercially not on a par with the new cultivars, still may possess some characteristics worth saving.

The pilot project involved 22 elementary and high schools. After collection, samples were determined, labeled, entered in registry books and statistically processed. A total of 5,296 samples of more than 40 plant species have been collected. The most active schools, students and teachers have been awarded for their efforts.

THE ZP SYSTEM OF THE PRODUCTION, DRYING, PROCESSING AND PACKAGING OF MAIZE SEED

 

Milovan Pavlov, Goran Saratlić, Živorad Videnović, Zoran Stanišić

 

Institut za kukuruz „Zemun Polje“, Beograd – Zemun

 

The idea of the maize seed production system implementation was born at the Maize Research Institute, Zemun Polje, almost half a century ago. This system encompasses the utilisation of scientific achievements - patents (released hybrids), environmental conditions, drying, processing and packing plants, experts and means of transport. The ZP system provides financial interests of all participants included into the production and also provides the seed production in sufficient amounts not only for national but also for international markets.In Serbia, climatic conditions are favourable, while soils are of good physical and chemical properties. There are eight processing plants that can process maize seed according to the modern technology. Several generations of experts within a maize seed production field have been educated and gained experience. Three seed testing laboratories were accredited pursuant to the international ISTA standards. The legislation regulations of the Republic of Serbia provide seed control not only in fields, but also in processing plants. This control is performed by authorised governmental institutions. Due to stated, this is the best model in agriculture and it should be provided that seed made in Serbia has a national character.The aim of the present study was to point out to the fact that the Maize Research Institute, Zemun Polje, has been contributing to the development of the maize seed production, processing and packaging in Serbia and that this system is today a contemporary business model applied in agriculture. Some of the most important elements of the ZP system of the production organisation, processing and packaging of basic and certified maize seed were discussed in this paper.

NS SMALL GRAIN SEED PRODUCTION AND MARKETING IN THE PERIOD 1998 – 2007

 

Gojko Mladenović,  Nenad Kovačević, Slaviša Štatkić

 

Institut za ratarstvo i povrtarstvo Novi Sad

 

The small grian production in Serbia is based on the cultivars developed at Institute of Field and Vegetable Crops in Novi Sad, which are grown at more than 90% of the total small grain acreage. Breeding teams of the Institute have developed over 300 cultivars of winter wheat, barley and triticale. These cultivars have a high genetic yield potential, excellent technological quality and very good resistance to the prevalent diseases, loding and winterkill. In the period 1998-2007, Pobeda, Evropa 90, Renesansa, NS Rana 5 and Pesma were the leading wheat cultivars in Serbia, covering over 75% of the total acreage. In addition to them, some 15 cultivars differing in production and technological characteristics were regularly placed on the market. In the period 1998-2007, the annual seed sales of winter wheat, barley and triticale were about 900,000 t, 50,000 t and 3,000 t, respectively. Small grain seed production does not accept radical and rapid changes in the assortment. Still, the production in the coming years will have to encompass a continual introduction of new cultivars with superior production and technological characteristics.

After harvest of perennial forage grass seed, a certain period of ripening is needed so quality can be acheived. At seed lot of cat's tail (Phleum pratense L.), variety K-15, and franch raygrass (Arrhenatherum elatius L.) variety K-12, changes of germination energy (%) and total germination (%) were studied. At every thirty days, starting from day of seed harvest, untill 240th day,  germination energy (%) and total germination (%) were determined using standard methods.Common cat's tail seed had shown best quality at 30th and 60th day after harvest, which is statisticaly more significant than determined germination energy (%) and total germination (%) in period of 120 and 240 days. On contrary, seed of franch raygrass had the best quality at 210th day arfer harvest, while straight after harvest until 120th day, the values of germination energy (%) and total germination (%) were signignificantly lower.By simple pair correlation (r), the correlation of mass of 1000 seeds (g) with germination energy (%) and total germination (%), was determined. At both of species correlation coefitients had not shown correlation between mass of 1000 seed and germination energy (%) or total germination (%), while germination energy (%) and total germination (%) are in almost total correlative dependance.

Sreten Terzić, Jovanka Atlagić, Vladimir Miklič, Siniša Jocić, Zvonimir Sakač

 

Institut za ratarstvo i povrtarstvo, Novi Sad

 

Three commercial sunflower hybrids (NSH2023, NSH2026 and RIMI) were used in this work, and their parental lines. They were grown in different pollination conditions: in isolation cages (hand pollinated and with bumblebees) and outside of isolation cages (open pollinated and self pollinated). We determined the pollinator visit, pollen viability, nectar content and seed yield.The pollinator visit was highest with hybrids, followed by restorer, A and B lines. The bumblebees visited A lines the most followed by the hybrid, B and restorer lines. Pollen viability was very high (>90%) in all male fertile genotypes except B lines in which it varied between 79 and 80%. Nectar content was highest in male sterile lines (1.3 μl), while B lines, hybrids and restorer lines showed lower quantities (0.9; 0.6 and 0.5 μl).The correlation coefficients showed highly significant influence of pollinator presence and pollen viability on seed yield. The nectar content was not significantly influenced with pollinator visit. The analysis of variance for seed yield showed significant difference between the analyzed genotypes and the pollination conditions, as well as their interaction.

Šumarski fakultet, Beograd,

 

Beech (Fagus moesiaca /Maly/ Czeczott.), sessile oak Quercus petraea (Matt.) Liebl.) and pedunculate oak (Quercus robur L.) are broadleaved tree species with high importance in both Serbian and European forestry. These species are characterized by seed production periodicity (3-5 years) and belong to group with recalcitrant seeds, which make special demand about processing and storage. One of most serious problems during storage are made by fungi Sclerotinia pseudotuberosa. This fungus is successfully suppressed by process known as thermotherapy. In this paper is represented existing methods of oak and beech nuts thermotherapy used in forestry, together with proposals of their modification, with special emphasis on physiological and technological aspects of improvement.

Institut za ratarstvo i povrtarstvo, Novi Sad

 

The rapeseed is grown for production of oil which is used either for human consumption or for further processing. The meal that remains after oil extraction is used as animal feed. Insecticide and fungicide treatment of rape seed is increasingly applied, as an ecologically and economically friendlier alternative that chemical treatment of diseases and harmful insects in the early phases of crop growth. In this study, effects of different combinations of fungicides and insecticides on seed viability of the rapeseed cultivar Banaćanka were assessed in seeds stored for 15, 18 and 21 months after treatment. Seed viability was tested using conventional laboratory methods on filter paper and sand. The tests included six chemical preparations that are most frequently used for seed treatment. Significant reduction in viability was observed after 18 months of storage in all pesticide combinations as well as in the untreated control. The obtained results served to recognize the pesticide formulations and concentrations that had not shown negative effects on seed quality.

Seeds of the majority of aromatic species according to the preservation time has been classified into categories expressed as index 1 and index 2 (Ujević 1988). Basil was designated as index 2, which means it retains germination at the percentage higher than 50% after 3-5 years of preservation. The purpose of this study is to test the viability of seeds (germination energy and total seed germination) and mass of 1000 seeds of domestic basil populations. The subject of this research were ten domestic basil populations designated from T-1 to T-10 and as such deposited in the Plant Genes Bank of Serbia. The seeds of domestic basil populations produced in the period from 1999 to 2003 were studies. The seeds were preserved in uncontrolled conditions and in single-layered paper bags. The research was conducted in the course of 2004. Determining seed quality was performed according to ISTA standards. The obtained study results point to significant maintenance of viability of basil seeds during their preservation in uncontrolled conditions.

REPRODUCTIVE TRAITS OF HERBACEOUS PLANTS

           

Mladen Mirić

 

Serbian Association of Plant Breeders & Seed Producers

 

Successful mastering of the plant production means knowledge of at least 200-300 biological, botanical, physiological, taxonomic, genetic, ecological and technological traits of each plant. These traits are essential in plant breeding and reproduction in seed production, field crop and vegetable production, then for plant gene banks, institutions for releasing varieties and approbation of seed crops. The analysis of 25 representative monographs published in our country show that each of these books encompassed only a few, no more than about 60 traits per species, which does not satisfy contemporary needs. Therefore, this study includes approximately 600 elementary terms on traits of herbaceous plants, that are classified into four groups: (1) generative and reproductive traits, (2) properties of generative organs, (3) seed properties and (4) properties of ecology and cropping practices. This thesaurus (Thesaurus eruditionis) is a common basis for making lists of properties of each crop, by the use of national and international biotechnological literature. Based on more complete data it is possible to make more reliable: descriptions of varieties, technological systems of the production of seed, field and vegetable crops and to innovate a plant classification, as these phenomena have not been based yet on such fundamental information.

Onion (Allium cepa) could be produced in several ways, depending on aim of production. So, onion seed germinates in very different conditions, especially temperature conditions (early spring sowing, autumn sowing, pre- winter sowing, summer sowing, sowing in controled conditions).  Basic seed-production and technological demand is detailed evaluation of onion seed characteristics and prediction of their appearance in different germination and emergence conditions. Germination of adopted cultivar-population „Holandski žuti“ has been investigated in this work. Cultivar has been maintainced for use of DPP „Mitrosrem“ from Sremska Mitrovica. Out of seed-crop onion plants have been separated and seed has been harvested by hand, control fraction and three seed- size fractions on mashed rectangle sieves has been separated: small sized seeds (1,00-1,80mm), medium sized seeds (1,80-2,20mm) and large sized seeds (2,20-4,00mm). Germination testing of onion seed has been done under five temperature regimes: t1=100C const, t2=200C const, t3=10/200C (8/16h), t4=5/150C (8/16h), t5=10/300C (8/16h). Germination of seed has been done on filter paper in germination chambers. Each fraction has been tested for 10x50 seeds. All experimental datas has been calculated for total variability (x and C.V.), three way factor variance analisys and correlation analisys (D, R and r).

Except that some quality traits of seed (protein contents, sedimentation of proteins, contents of vet and dry gluten, quality class) were investigated. The highest grain mass spike-1 was established in KG-3097 (2.62g) and the lowest in KG-3075-1 (1.86g).  The highest average thousand grain mass had line KG-1/74-93 (48.5g) and the lowest  KG-3027 (38.10g) while the highest grain hectoliter mass expressed KG-3008-1 (89.7 kg hl-1) and the lowest  KG-3625 (85.3 kg hl-1).  The highest average grain yield had wheat line KG-3625 (9475 kg ha-1). According to average values of quality traits, the line KG-3027 was the best, which expressed  the highest value of protein contents (14.2%),  protein sedimentation volume (54 ml). The phenotypic similarities of lines were studied according to examined traits. The similarity of genotypes were computed by cluster analysis. In dendograms were expressed clusters of the most similar genotypes which are connected at the higher hierarchical level.

Institut za kukuruz „Zemun polje“

 

Seed quality influences directly the crop productivity and it can be considered as a combination of genetic, physiological and sanitary attributes. The isolation of the seed production fields, the removal of the female parental tassel, the cleanning of the harvest and processing machinary are some of the criteria adopted to maintain the genetic purity of maize hybrid seeds. In spite of this genetic purity analysis is extremely important, particularly with breeder and foundation seed.Genetic purity certification in maize has been mostly performed using morphological traits. Today, sophisticated laboratory techniques such as starch gel electrophoresis and isoelectric focusing are available to conduct genetic purity analysis. These techniques have the advantages of increased precision and speed, but the disadvantages of cost and complexity. Isozyme electrophoresis testing is powerful and effective method for accurate detection of unwanted plant types in maize hybrid and inbred seed lots. However this method is time and money consuming in comparison to Ultra-thin isoelectric focusing (UTLIEF) of seed proteins, which has been included in the International Seed Testing Association rules for variety verification (ISTA, 1999.). This technique is considered to be convenient, cheap, quick and reliable method for maize genetic purity determination. Further advantages of UTLIEF over isozyme electrophoresis will be presented on the poster.

Evaluation of turfgrass seed material for landscape planning and horticulture as well is based on specific parameters differ than those applying in grasslands for pastures and meadows i.e. animal nutrition. Visual and functional properties are analyzed in turfgrasses (for sport, recreation and decoration). Visual properties are: ground cover, turfgrass density, texture, uniformity, color, establishment, tillering, flowering, presence of the weeds, mowing, drought and frost tolerance, disease and insect demage. Functional properties are compression and traffic tolerance, elasticity, ball rolling, mowing, rhizome and stolone development and thatch accumulation. Approving and registration of new turfgrass varieties is based on above mentioned parameters. Having in mind that turfgrasses are not used in animal nutrition, assessment of seed infection with pathogens is not of such importance as it is with agricultural plants, and has effect on market value and thus availability.

The trial with 7 maize hybrids with different seed quality (originated from the same year and different locations) was set up.  The seeds were soaked in water, 2,4-D solution (germination and growth stimulator) and colloidal suspension of Super-Hydro-Grow polymer as osmoticum (water absorption limiting). The germination ability and seedling growth was attended, depending on applied treatments. The 2,4-D increased germination (12 %, averagely), as well as fresh weight of root (10 %) and reduced fresh weight of shoot (6 %). The SHG decreased 25 % germination and fresh weight of root and shoot 22 and 24 %, averagely. Significant raise of dry substance concentration in seed rest and free energy lower input by water, particularly free energy of hydrolysis and biosynthesis resulted in lower seedling growth. Meanwhile, multiply ascended hydrolysis and reduced biosynthesis in hybrid with starting germination of 25 %, pointed out membrane injury and seed content exudation in SHG treatment.Irrespective to genotype, the obtained results underlined importance of seed rest in 7 days old seedlings, representing limiting factor for germinating and sprouting, since it is still active in supplying of free energy and hydrolysate, necessary for growth and development.

Researches which lasted two years were carried out on two locations. In this trials was investigated influence of three sowing dates (with 10 days intervals) on the seed quality of three seed corn  female lines (L1-FAO 400, L2-FAO 500, L3-FAO 600), and male line (L4). After harvesting parameters of hybrid seed quality (germination and seed weight) were determined.  Statistically significant influence of sowing dates and lines on the quality of hybrid seed was gained. Sowing times are demonstrated significant influence on germination and seed weight at all investigated lines. In the first year germination of tested lines hybrid seed are significantly difference in dependence of sowing dates and ranged over from 95,0 to 97,9%.

Autochotic cultivar-population of paprika Kurtovska kapija could be produced from  nurssery plant  and  from direct planting. In both cases, seed characteristics are of largest importance. Tested seed in this work has been produced in 2005th year for use in DPP ''Mitrosrem'' in Sremska Mitrovica. Seed production has been produced from direct planting.

Processed seed material has been separated into five seed size fractions on sieves with rectangle mashes: small seed (<3.25mm), medium small seed  (3.25-3.50mm), medium large seed (3.50-3.75mm), large seed (3.75-4.00mm) and very large seed (>4.00mm). Following physical-mechanical and phisiological seed characteristics have been tested in laboratory: number and mass of seed in 1l; number of seed in 1kg; mass of 50 seeds; seed germination (speed germination and total germination). Calculation of experimental datas has been processed depending of seed characteristics: variation order (X; S.D.; C.V.); two-way factorial variance analysis (with seed-size fraction and germination testing temperature as factors); corelation analysis (D; R; r). Germination testing has been under three temperature regiemes with 10*50 seeds for each testing variant. Obtained results are of importance for: paprika seed production and processing technology; testing and evaluation metodology of  paprika seed characteristics; comercial paprika technology production.

            Great fluctuations of yield and quality of seed among localities, as well as between the years, most often due to water lacking during formation and filling of seed, are present under our production conditions. Since soybean seed is produced under different agroecological conditions, the aim of this paper was to determine the parameters relating to quality of seed (purity, germination, moisture content, and mass of 1000 seeds) produced in 2006 and 2007, resepctively. Five varieties of soybean which according to length of vegetation belonged to different maturation groups were used in this study: O maturity group (Proteinka and Valjevka), I maturity group (Balkan and Ravnica), andi II maturity group (Vojvođanka). Testing was done according to current Rule on seed quality of agricultural plants (Official magazine SFRJ 47/87) in the National laboratory for seed testing in Novi Sad. Production conditions in 2006 were favourable for soybean seed production which resulted in high quality of seed. Seed purity of tested varieties ranged from 98 to 99,9%. Germination of seed was high above the prescribed minimal value (75%), and ranged from 86 to 98%. Agro-meteorogical conditons in 2007 were unfavourable for soybean seed production due to lacking and poor distribution of rainfalls, and high temperatures, esspecially during formation, and  filling of seed.   Unfavourable production  conditions  had  negative  influence  on  seed  purity  which  ranged  from  96,4 – 99,9%. Germination of seed ranged from 62 to 98% and depended on variety.

Sclerotinia sclerotiorum causes white rot desease in plants and has a very wide range of hosts; the most sensitive are the plants from Asteraceae (sunflower), and Fabaceae (soybean, bean, string bean) families. Fungus overwinters in the nature in the form of sclerotia and micelia in the soybean seed. The seed health testing is done under laboratory conditions as one of the most important parameters of seed quality. According to the Rule on health testing of seed, seedlings and planting material ("Official magazine of RS" 119/07), the soybean seed is allowed to have 10% of infection caused by S. sclerotiorum. Some 30 individual soybean samples were included in our investigation, and average seed infection produced at different localities in Vojvodina (Vrbas, Bačka Palanka, Srbobran, Rimski Šančevi) during 2005, 2006 and 2007 was determined. Isolation, identification and determination of Sclerotinia sclerotiorum  were done on PDA nutritive medium according NSHS Sf 3.1. method.  Seed incubation was done during 10 days at 25 ºC, and infection was estimated after 3, 5, 7 and 10 days. The fungus developes characteristic and easily recognized colonies. Fungus micelia is white or cream in colour, and sclerotia are developed regularly, mostly at e edges of the colony. Our results pointed out to relatively low infection caused by this fungus, and the average infection over the years ranged from 0,25-3,25% in 2005, 0,25-1,75 % in 2006, and 1,50-2,5% in 2007.

Adoption of modern agricultural production made the agricultural producers to become more aware of significance of high quality seed capable of rapid and uniform germination under different environmental conditions.Differences between seed lots can not be readily noticed under conditions favorable for germination, however, they are easily noticed when seed is exposed to unfavorable germination conditions. The aim of this paper was to determine the quality of treated wheat seed by applying different tests for vigor seed determination.Testing was done on three commercial wheat seeds (Pobeda, Kremna, Evropa 90). Seed was fungucide treated (Zorosan liquid, Mankogal S, Raxil 060 FS, Benlate, Sumi-8 2 FS, and Vitavax 200 FF). Besides standard germination test, the tests for vigour determination were also used (intensity growing test, cold test, accelerated aging test, and Hiltner test).Application of accelerated aging test revealed lower values for seed germination in comaprison to other tests. Applied treatments, except Zorosan liquid, had no negative effect on seed germination and growth of above ground part of wheat seedling. Length and mass of the above ground part and root system of wheat seedling were the highest in seed treated with Mancogal S and Vitavaxom 200 FF. Seed germination as well as seedling growth depended on genotype.

Nacionalna laboratorija za ispitivanje semena, Novi Sad

 

Being familiar with seed aging of individual plant species, as well as with the influence of different factors on seed aging is of great practical significance.Seed aging, i.e. seed longevity can be of  biological and economic origin. Economic seed longevity encompassing the period in which seed can preserve its technology and market value is more important for agricultural production. Seed longevity depends on plant species, genotype, and storage conditions. Having the above mentioned in mind, the aim of this paper was to determine the intial quality of pepper, tomato and cucumber seed, and the quality of one year old seed stored under common storage conditions. Quality traits (germination, moisture content, and seed health) of pepper (Krušnica, Horgoška slatka 2, Matica and Atina), tomato (Novosadski jabučar, Bačka, Knjaz, Alparac), and cucumber (Parisko kornišon, Sunčani potok) seed produced in 2006 were tested - the same one year old seed was also tested. The moisture content and seed health remained unchanged after one year aging in all tested varieties. Decreased germination, but not statistically significant was found in one year old  pepper and cucumber seed. Germination of tomato seed depended on variety. In Knjaz variety germination remained unchanged, while in other varieties statistically significant decrease of the tested parameter was found in 2007.

The effect of temperatures, t1-20/40oC (alternately 12/12 hours) and t2-10oC const. (cold- test), on germination of two sweet maize hybrids (ZP SC 401su and ZP SC 504su) including two  seed shape fractions (flat and rounded) and four seed size fractions (small, medium small, medium-large and large), was observed in the present study.Prior to carrying out these observations, 10 x 50 seeds were analysed and the following traits were determined: dry seed prior to germination (m0), whole dry seed after germination (ms), dry endosperm after germination (me), dry embryo after germination (mk) and the loss of dry weight during germination (Δm) and total germination.The experimental data were processed as the average and the total variability (x and C.V.), and were presented for each hybrid combination individually over the seed shape and size fractions.Obtained results show that seeds of different fractions differently responded to extreme heat conditions by their germination ratio. Furthermore, hybrids also responded to applied thermal treatments in a different way. Based on this information, the dynamics of successive sowing of sweet maize can be estimated.

For providing bigger total production of wheat as well for achievement stable yield is necessary to use quality seed for sowing. By finishing off seed and testing its quality, seed becomes declared and gives possibility for achievement of high and stable yields. Declared seed has high variety purity and high percentage of germination. In this paper are showed results of some quality parameters of winter wheat seed (purity, falling seed through the sieve, number of weed seed in 1000 g and germination) in tests which are done after the harvest and than after finishing off seed. The process of finishing off seed was significantly influenced on improvement of all followed quality parameters.

Centar za poljoprivredna i tehnološka istraživanja d.o.o, Zaječar, Srbija

 

Seed-zone water content is the main factor controlling seedling emergence and survival. Sometimes, cereals in semiarid regions with dryland farming have to germinate with unfavorable seedbed conditions. In such years poor stand establishment is the most important factor affecting cereal grain yields. This study reports on genotypic variation in wheat for germination percentage (GP), coleoptile (CL) and total seedling length (TSL) under normal and water stress conditions. One hundred wheat (Triticum aestivum L.) genotypes of worldwide origins, were placed on filter paper moistened with either distilled water or polyethylene glycol 6000 (PEG) solution at -0.4MPa potential. GP, CL and TSL were measured on three occasions in two consecutive years. Variations of GP, CL and TSL were statistically significant in both treatments. TSL ranged from 11.9 to 119.5 mm in well-watered and from 0.5 to 63.7 mm in PEG. TSL reduction due to PEG ranged from 36 to 97%. Osmotic treatment delayed initiation of seed germination from 1.7 to 10.7 days and reduced GP from 1 to 91%. Thus, considerable genotypic variation exists for germination potential and young seedling growth under droughted conditions. Relationships among the traits were examined by correlation analysis.

An important prerequisite for achieving high yield of soybean is securing the recommended stand at harvest. The main target of seed processing is to provide growers with quality seed, capable of securing a desired number of plants. The objective of this study was to see whether seed size, i.e., seed fractions, does or does not affect soybean seed viability. Experiments included five soybean cultivars (Jelica, Afrodita, Balkan, Novosađanka and Vojvođanka), which were tested for two years (2006 and 2007). The treatments were non-calibrated soybean seed, which served as control, and three fractions, 4.5-5.0 mm, 5.0-5.5 mm and > 5 mm. In 2006, which was not favorable for soybean production, no difference in seed viability could be found either among the fractions or among the cultivars. In 2007, which had several stress periods in the course of soybean growing season, seed viability was reduced. Statistically significant differences in seed viability were registered among the cultivars, but not among the fractions of either cultivar.

One of the most  important maize hybrid seed  characteristics is follow of its germination and relation to temperature conditions during germination. Every next  move in  comercial production of  hybrid maize depends on this morpho-physiological and  morpho-genetical process. So, research of  chnges during hybrid  maize seed germination is one of the most important aspects of hybri maize seed production.

Maize hybrid seed germination of  two SC combinations  with the  same  parental ant two  different  maternal parents has been researched in his paper. Seed  material has been calibrated  to six fractions (according to seed  shape and size). Changes  during germination under standard conditions (t =20/30 oC, 16/8 hours) and cold – test conditions (seven days t =10o C, then 20/30, 16/8 hours)) have been, researched. Following changes have been  measured: mass of swelled seed; mass of seedling; dry mass lost during germination; nmber of normally germinated seeds.Experimental data have been  calculated  to total variability (X and C.V.); two-factor analysis of variance (factors: hybrid combination and seed – fraction); correlation analysis for each  hybrid combination (D;R;r;PATH coefficient analysis).These results are of great importace for methods of testing and evaluation of hybrid maize seed characteristics.

The three-year four-replication trials with two sowing densities were set up according to a randomised complete block design under conditions of irrigation in two locations in order to determine the effects of a proportion and a size of a vegetation area of parental inbreds on the 1000-seed weight in maize hybrids ZP 42 A and ZP 704. Hemp was sown in border belts of 3.2 m in width that were the isolation between experimental variants. The number and the arrangement of parental rows were 4:2 in favour of a female component. The number of plants per area unit amounted to 55,000 and 65,000 per hectare. The inter-row distance for the female component amounted to 70 cm, while there were the following two distances for the male component: 70 cm and 50 cm. The proportion of areas under female component plants amounted to 66.7 % and 72.2 %. A statistically high significance of the environment, a hybrid combination and densities was determined by the analysis of variance for 1000-seed weight. Also, statistically high significance (99%) was registered for the first order interactions: (environment x inter-row distance of male component plants), (hybrid combination x inter-row distance), (environment x rows of female component plants) and (hybrid combination x density-number of plants). Furthermore, statistically high significance was expressed by two second order interactions: (environment x inter-row distance of male component plants x density) and (environment x rows of female component plants x density).

INTEGRAL TEACHING OF THE SEED PRODUCTION

           

Mladen Mirić

 

The paper encompasses the analytical component in which topics related to seed production academic studies such as activities, occupations, science, teaching, lecturers, books, textbooks, journals, reviews, terms and principles of the seed production are briefly discussed. There are two basic objectives of this study. The first objective is a proposal of the teaching programme that will provide rationalisation of managing activities in the seed production in a way that an expert profile will be educated with all necessary abilities to be granted all legislation rights to perform activities of responsible experts in the seed production. In such a way, instead of employing several graduated students, only one expert will be employed, as they will have an integrated set of knowledge on operations required by the law: seed multiplication, trade and processing, crop and seed protection and their control and check, seed production and agricultural techniques, cropping practices, then on the participation in the operations performed in gene banks, seed sampling, seed testing and similar. The second objective of this study was an attempt to elaborate one of possible concepts of doctoral studies within the field of seed production, since this possibility has became reality and responsibility of the faculty in recent times.

Agroecological condition of production of seed crops of maize leads  to different expresing of characteristics of hybrid seed that are very important for  processing and utilise value. Some of it  seed characteristics  simulate limiting   factor for mainteining and extending it hybrid maize  combination in comercial production. In paper is studied  physical-mechanic and physiological  characteristics of hybrid seed of two domestc SC combination (comercial). Physical-mechanic characteristics that are researched are: number and mass seed in 1ℓ; number of seed in 1 kg; mass of 100  seed. From  physiological seed charactristics  indicators of germination (speed germination and total germination) are tested under standard  condition (t =20/30 alternate 16/8 hours). Seed material is previously  calibrated in six fraction. Experimental data are processed  with  two factors analysis of variance  as variation order  (X; S2; S.D; C.V),factors are (seed fraction and SC combination) and with correlation analysis (D;R;r). Results are very important for technology of production and technology of processing of hybrid maize seed.

The trial with 3 maize hybrids with different seed quality (from 3 seed lots) was set up. The seeds were kept during the three years in standard warehouse circumstances. The quality of examined seed lots were analysed, with standard and vigor methods, considering, Cold test, TTC method, accelerated ageing (followed by standard germination test and TTC method).

Starting values of germination were: from 90% in H2 to 95% in H1. Seed keeping in standard warehouse circumstances decreased germination percentage from 1%, in H3, down to 12%, in H2. Moreover, starting germination values were even lower, after Cold test applying, to 5%, in H2. The similar results were obtained after TTC method using. Subsequently to three years of seed keeping, germination percentage was lover 1-7% evaluated by standard germination method, with additional decrease of 5-12%, derived from Cold test application. Accelerated ageing method reduced germination percentage moreover.

Inter-laboratory proficiency tests (ILPT) are comparison tests carried out with the same or similar samples by several laboratories with the aim to check laboratory proficiency. The participation in these tests is obligatory for all accredited laboratories (SRPS ISO/IEC 17025), including seed testing laboratories. Also, seed testing and issuance of reports, i.e. certificates on seed quality can be done only by accredited laboratories (Constitution of ISTA, Low on Seed, 2005).The International Seed Testing Association (ISTA) launched inter-laboratory proficiency tests for all member laboratories at the beginning of 1990s. The ISTA accredited laboratories in Serbia have been performing tests since 2000 on the basis of the ISTA model of the sample preparation and statistical processing of the obtained results. Until now, there have been 11 rounds, with  11 species and 24 tests. These tests are applied to audit: a) staff competence; b) accuracy of laboratory instruments; c) application of validated methods of testing, processing and presentation of results. In case that any laboratory obtains results that significantly differ from the mean of remaining laboratories ILPT participants, that laboratory has to find the cause of the error, to take corrective measures, repeat tests and it has to submit the results of repeated tests to the ILPT organiser.This study presents results of ILPT  performed with Avena sativa during 2008. A total of 18 laboratories, out of which 14 are accredited by the Serbian Designated Authority, participated in this round. The following tests were performed: germination, purity and other seed count. Results are presented as a mean for all laboratories that participated in the ILPT.According to obtained results it can be concluded that the accreditation of laboratories increase the proficiency level and thereby quality of services offered by seed testing laboratories.

Institut za kukuruz “Zemun Polje”, Beograd – Zemun

 

Proteini soje sadrže sve esencijelne amino kiseline a po svom kvalitetu se približavaju proteinima životinjskog porekla. Sirovo zrno soje takođe sadrži i kompleks antihranljivih supstanci, koji onemogućava korišćenje sirovog zrna soje u ishrani ljudi i domaćih životinja. Najbitnijom supstancom sa inhibitornim delovanjem smatra se Kunitz-tripsin inhibitor, tim pre što je termostabilniji u odnosu na druge sastojke. Ogovoran je za 30-50% ukupne tripsin inhibitorske aktivnosti, i čini oko 6% ukupnih sirovih proteina u zrnu. Tripsin inhibitor deluje tako što blokira dejstvo enzima koji razlažu proteine u organizmu domaćih životinja posebno nepreživara. Posledice toga su zaostajanje u rastu i razviću životinja. Kao početni materijal za stvaranje novih sorti koristili smo američku sortu Kunitz, prvu registrovanu sortu sa ovim svojstvom. Sorta Laura pripada I grupi zrenja, i preporučuje se za sve regione gde II grupa problematično sazreva. Predviđena je za direktnu upotrebu u ishrani odraslih živitinja nepreživara. Sorta je neograničenog tipa rasta, malje su žute, cvet beo a hilum crn. Preporučuje se gajenje u gustini od 450 000 biljaka po hektaru. Po prinosu zrna je ravnopravna sa sortama I grupe zrenja koje su kod nas raširene u proizvodnji.

            Although once one of the most significant legume crop in both human nutrition and animal feeding, field bean in Serbia today is nearly completely forgotten, without any statistical data. Among the most important goals of the annual forage legumes breeding programme in the Institute of Field and Vegetable Crops in Novi Sad are both conservation and sustainable utilisation of field bean genetic resources, mostly in the form of breeding for grain, forage and green manure. Several dozens of field bean accessions of diverse geographical origin, included in the institute’s Annual Forage Legumes Collection (AFLCNS), served as an initial material for the development of hybrid populations and the selection of lines with desirable agronomic characteristics related to yields of grain, forage and biomass. Such two lines, B-412 and B-413, had better average two-year results in comparison to the cultivars from the national list, such as the Czech cultivar Uran, with emphasis upon grain yields of more than 4500 kg ha-1 and green forage yields of more than 45 t ha-1. During 2006 and 2007, these two lines were included in the official state trials, were characterised by significantly higher grain yields in comparison to the control cultivar, and, as a result of the former, were registered under the names of Gema and Šarac.

Slobodan Katić, Vojislav Mihailović, Dragan Milić

 

Institut za ratarstvo i povrtarstvo, Novi Sad

 

            The alfalfa cultivar Nijagara was developed at Forage Crops Department of Institute of Field and Vegetable Crops in Novi Sad and officially approved in 2007. The source material was obtained from Prof. E.T. Bingham, Agronomy Department, University of Wisconsin, Madison, WI, USA. Plants from the 7th generation of selfing (S7) were derived from the cultivars Vernal (V18), Saranac (S20) and the cross Saranac x Vernal (SV42). Crossings were made in greenhouse following the scheme S20 x SV42 and then V 18 x (S20 x SV42). The obtained progenies were multiplied from F1 to F4 generations, in the field, at Rimski Šančevi experiment field. Nijagara differs from the cultivar Vernal in that it has a smaller number of yellow and variegated flowers and it is similar to it in the dark green leaf color. The other characteristics such as plant height, leaf ratio, stem diameter, and growth rate are similar to those in the cultivar Saranac. In the 4-cuts growing system, Nijagara performs similar to the other domestic cultivars. In the tests of the Commission for Variety Approval, Nijagara's yield performance was on the level of the cultivar NS Mediana ZMS V. However, the content of crude proteins was higher by 0.5% in Nijagara as compared with NS Mediane ZMS V. Nijagara has a branched root system and it tolerates poor and slightly acid soils, similar to the cultivar Vernal. Nijagara is resistant to the bacterial wilt, downy mildew, spot and black rot, similar to the cultivar Vernal. Further, it is resistant to anthracnose and Verticillium wilt, similar to the cultivar Saranac, as well as to Fusarium wilt. Nijagara is more resistant to the diseases of the aboveground parts, crown and roots than any other domestic cultivar.  It is recommended for growing in humid regions (disease resistance), on poor soils (a branched root system) and on acid soil after calcium treatment.

NEW WHITE KERNEL MAIZE HYBRID

 

Milomir Filipović, Zorica Pajić,  Jelena Srdić

 

Institut za kukuruz „Zemun Polje“, Zemun-Beograd

 

Maize breeding in the USA and Europe was always more oriented to yellow kernel maize than to the white kernel maize. Therfore yellow kernel hybrids have higher yield potential, better stability and faster grain dry-down.In the 1990s in Maize Research Institute started incorporation of egzotic germplasm that had yellow and white kernel, adapted to drought in our continental, mostley yellow kernel germplasm. With the good knowledge of the heterotic patterns of the adapted and egzotic material, soon very good sources were formed, for obtaining new white kernel inbred lines. Two white kernel hybrids were obtained out of this program ZP 718b and ZP 766b. Advantages of the hybrids derived from this program are especially shown in dry years such as 2003 and 2007. In such years those hybrids show superiority in yield and have faster grain dry-down. The official two year trials of the Committee for the Release of Varieties in which hybrid ZP 718b was examined and released, showed that it was significantelly better than the standard hybrid of the group.The new hybrid ZP 718b has the lower plant, with the low set ear, and the erect maize leaves. The shape of the ear is cilindric, with high number of kernel rows. Those are the traits that also new modern yellow kernel hybrids possess.

NEW APPROACH IN MOLECULAR BREEDING FOR WHEAT GRAIN YIELD

Institut za ratarstvo i povrtarstvo, Novi Sad, Srbija

 

Present knowledge related to molecular marker technologies offers a range of possible novel approaches to improve efficiency of wheat breeding programs worldwide. So far, conventional breeding have obtained increased grain yield by selection of high yielding phenotypes rather than of desirable alleles presumed or known to improve either grain yield per se or grain yield-related traits. For many reasons this strategy is limited in both efficiency and potentials. Molecular markers closely linked to genes of interest are very useful for marker assisted selection (MAS) and pyramiding of two or more desirable genes into a single genotype. To ensure optimal cost-effectiveness, molecular markers used for MAS should both enable efficient screening of large populations and show high degree of reproducibility across laboratories. The close interaction between breeders and biotechnologists may also improve and accelerate the effective implementation of marker assisted selection in breeding programs. In this paper the new approach in molecular breeding for wheat grain yield is proposed. Using this approach we were able to determine potentially desirable segments-alleles of the wheat jigsaw puzzle responsible for increased grain yield in target environment.

Institut za kukuruz „Zemun polje“

 

The unique collection of local populations is considered the most valuable resource of the Maize Research Institute genebank. A high variability of these genotypes has been determined, since the collected material originates from almost all eco-geographical areas of ex Yugoslavian territory. The diversity of maize eco-types and habitats from which the genotypes were collected represents a good potentiality for improvement of elite maize material. The collection of domestic maize populations has been fully characterized in line with the IBPGR/CIMMYT descriptor. Since the 1990-ies there has been a huge increase in the application of molecular marker techniques to problems relevant to the conservation and use of plant genetic resources. A variety of different techniques for detecting and analyzing variation at the molecular level are now available and offer ways of improving effectiveness of plant genetic resources management. Application of molecular markers in the analysis of local populations from Maize Research Institute Genebank includes: genetic characterization and creation of sample genetic identification cards, identification of duplicate accessions and genetic diversity assessment, as well as identification of new sources of beneficial traits such as herbicide resistance, drought tolerance and cytoplasmatic male sterility.

Effects of induction media and cold pretreatment on callus yield and regeneration ability of wheat anthers in in vitro culture have been investigated. Anthers were isolated from 12 wheat (Triticum aestivum L.) genotypes. Half of the anthers were exposed to cold pretreatment at 4±1°C for 5-10 days, while the other half were immediately isolated and inoculated onto induction media. Two media were used for callus induction, Potato-2 and N6. Anthers with and without pretreatment were inoculated onto both media. Significant differences were found between the media only in regard to regeneration ability of calluses obtained from anthers, which were exposed to cold pretreatment. In the absence of pretreatment, differences in androgenous and regeneration abilities on different media were not significant. Absence of pretreatment, with both media, had no significant effect on callus yield and regeneration ability of wheat anthers. However, on Potato-2 medium, callus ability to regenerate green plants was increased in the absence of pretreatment. On this medium, callus ability to produce green plants in the groups with and without pretreatment was 18.9% and 27.1%, respectively. Differences between the corresponding values on N6 medium were not significant (27.1% and 24.5%, respectively).

Considering the improvement of the concept of nursery production, i.e. tendency of cessation of planting material production at the species level, better understanding of genetic potential of Austrian pine provenances is necessary, since its directed application would improve the production of seed and planting stock and lead to greater success in afforestation and cultivation of dedicated plantations of this species. The object of this study was research of  intra- and interpopulation genetic variability of Austrian pine by application of biochemical markers. Polymorphism of protein markers is determined among genotypes sampled from six provenances (seed stands), by which all Austrian pine populations in Serbia are encompassed. Based on acquired electrophoregrams qualitative and quantitative differences (number and allocation) of protein fractions are determined. Also, protein profile of the seeds for each tree and for each provenance individually (out of six studied) are determined. On this occasion "conservativity" of certain polypeptides is noticed, i.e. their presence in all examined genotypes. On the other hand, protein fractions variable at the level of the populations are determined, and also the ones that show variability which varies depending of the population. Based on acquired electrophoregrams the genetic similarity coefficient and genetic distance are calculated by comparing of the number and allocation of the bands and cluster analysis dendrograms are made. Greater extent of genetic variation is determined among provenances then within the respective provenances. Great intrapoulation genetic variability of seed proteins is also determined for the populations studied.

In recent years food produced by genetic engineering technology have been on the world food market. In this work, raw and processed maize samples were analysed for genetic modification using a DNA based detection method, the Polymerase Chain Reaction (PCR). In total 119 samples, 99 samples of maize seed and 20 processed maize food were collected from different markets and distributers. The samples were examined for the presence of genetic elements located in the majority of transgenic crops such as NOS terminator, CaMV 35S promoter, using conventional PCR. The GM positive samples were analyzed by Real-Time PCR assay. In 8 samples of maize seed presence of 35S or NOS were identified and in processed food transgenes were not detected. The estimated amounts of GM maize in these samples ranged between 0.1 and 0.9%, for most of them 0.2% or 0.3%. Obtained results showed that maize seed has been contaminated with GM seed. In the most EU countries the treshold for GM contamination of non GM seed has set, and low regulative in our country should follow them.

Genetic markers in contemporary seed production are used for: 1) inference of family relationships and mating system, 2) distribution of within-species genetic variation over space and time, 3) phylogeny reconstruction and 4) identification of expressed genes. Up to date, genetic markers was mostly used as tool in control of forest seed origin, in sense of identification of parental trees, and for establishing of minimal genetic diversity in seed lot, in order of within species diversity preservation. In Serbia, genetic markers are increasingly in use for defining of provenance regions of forest tree species. In this paper, we present experience and on going activities.

Institut za ratarstvo i povrtarstvo, Novi Sad

 

Good choice of pollinator is essential in development of successful commercial sugar beet hybrids. Beside desirable agronomic traits and resistance to pathogens, pollinators also must have high level of male fertility. In this investigation were used diploid multigerm populations (2n MM), potential pollinators in future hybrid combinations. Pollen vitality is very important biological trait which can be evaluated by different dying methods, after which meiosis analysis could be done. Anther samples were taken from flower buds in five populations grown in the field. Meiosis analysis showed that, in most cases, it went the regular way. The phases that were analyzed were: pahiten, diploten, diakinesys (prophase I), metaphase I, anaphase I, telophase I, metaphase II, anaphase II, telophase II, tetrads, microspores and pollen grains. Statistically, the highest percent of irregularities of meiotic cycle had populations 1 and 4, in all analyzed phases. Population 2 is potentially the best pollinator with lowest amount of irregularities and excellent pollen vitality.

Institut za ratarstvo i povrtarstvo, Novi Sad

 

The method of fluorescent microscopy for monitoring of pollen germination on the stigma and the pollen tube growth through the style and ovary to the embryo sac – egg cell, is the closest to in vivo fertilization monitoring. It is described in detail for tomato (Kho and Baer, 1968) and it was adapted for application on sour cherry, buckwheat and even sunflower.This paper shows the results of method adaptation for sunflower and the possibilities of its application for parental lines compatibility studies in hybrid production, as well as the possibilities for interspecies hybridization monitoring in the genus Helianthus.Different periods were evaluated for style sampling (1-5 days after pollination), two fixation procedures (CARNOY I and FAA) and two types of pretreatments (1N and 8N NaOH). Staining was performed with aniline without the addition of fluorochrome (different periods of staining).The study showed that the method is applicable on sunflower for all tested sampling periods (optimally three days after pollination) with CARNOY I used as fixative and the pretreatment with 8N NaOH. The difficulty in application of this method is for the part of monitoring of pollen tube growth in the ovary area.

Starting point in marker assisted selection programs is analysis of genome polymorphism and development of markers linked to the genes of interest. The aim of this research is development of RAPD analysis as marker system in analysis of genome polymorphism in sugar beet. The research was conducted on eight sugar beet genotypes that were selected for their different response to water deficit in the field and the greenhouse conditions. The starting material was propagated in in vitro conditions. For PCR were used single RAPD primers A05, A07, A08, A19 and A20, as well as their combinations: A07/A08, A07/A19 and A08/A19. Use of both, single and combined markers resulted in multiple PCR products resulted in numerous PCR products. All markers detected DNA variability, which was expressed and presence or absence of different multiplication products. Considering stability of amplification and reaction yield the best performance was obtained from single primers A19, A20 and primer combination A08/A19. Exceptionally high level of polymorphism was detected in amplification products of primer A19 between 300bp and 1000bp. It should be further investigated as a potential source of useful markers.

Institut za kukuruz „Zemun Polje“, Zemun-Beograd

 

Application of molecular marker techniques in sweet corn has many advantages. The results of the molecular markers provide information about genetic divergency of the material and its grouping in different heterotic groups, estimates of hybrid performance and it leads towrd eficcient identification of genotypes with desirable traits.Many research programs, have not up to now succseeded to deterimne clearly defined heterotic models among sweet corn inbred lines. The reason for that is a very narrow genetic background on which the breeding of sweet corn is established. Only few open-pollinated varieties were the fundament of the almost whole breeding material of  sweet corn.We applied the technique of RAPD markers in this research in order to establish the genetic divergence among 6 sweet corn inbred lines, derived in Maize Research Institute „Zemun Polje“. The results of GD were correlated with information about pedigree, heterosis and SCA. The cluster that was obtained based on GD was in complete concurrence with pedigree data. Rank correlation coeficient between GD and heterosis, while always positive was not statistically significant. The correlation between GD and SCA was also positive, and in one estimate highly significant. That indicated that if there is larger distance between two lines, there is higher estimate of SCA.

GenetiC CHARACTERISATION OF ZP MAIZE HYBRIDS OF DIFFERENT TEMPORAL CYCLES OF SELECTION

 

Milosav Babić, Iva Bauer, Vojka Babić

 

Institut za kukuruz-Zemun Polje, Belgrade, Srbija

 

The obvious advantage of single cross hybrids, in spite of problems that had to be overcome in the seed production, was an actual milestone in the implementation of the phenomenon of heterosis. Since 1964, the Federal Commission for Approval of Varieties, has released over 500 maize hybrids developed at the Maize Research Institute, Zemun Polje. Since mid-1960s till nowadays, five cycles of selection could be singled out. These cycles are related, first of all, to the period of the introduction of new, improved hybrids into mass production. This study encompasses the characterisation of 30 maize hybrids derived at the Maize Research Institute, Zemun Polje. The RAPD markers, as molecular markers, were applied in this characterisation in order to determine the genetic relatedness among different cycles of selection. Genetic similarity coefficients were calculated after Jaccard and they were used in the cluster analysis by Ward's method and in the correspondence analysis. The cluster analysis, using Ward's method of a genetic distance, excluding the hybrid 4/6, clearly classifies hybrids into five cycles of selection contrary to the UPGMA cluster analysis by which such an apparent distinction is not possible. The first dimension of the correspondence analysis separates the fifth cycle from the first, second, third and fourth cycles. The hybrids of the third and fourth cycle of selection cannot be obviously separated, while the hybrids of the first cycle can be clearly separated by the second dimension from the hybrids of the second cycle. However, the genetic distances of individual hybrids from different cycles of selection show that some of these hybrids are closer to certain hybrids from other cycles of selection. The cluster analysis clearly classifies groups of hybrids over temporal cycles, while the correspondence analysis shows that classification into four cycles would be more appropriate in a genetic sense.

METHODS FOR MAIZE VIRUS DETECTION AND IDENTIFICATION OF GENES FOR RESISTANCE

 

Ana Nikolić, Dragana Ignjatović-Micić, Slavica Stanković, Dragica Ivanović

 

Institut za kukuruz „Zemun Polje“

 

Maize viruses can cause significant grain yield reduction. Different serological and molecular methods enable reliable and rapid identification of plant viruses. The most frequently used serological methods are ELISA (Enzyme-Linked Immuno Sorbent Assay) and Western Blot, while RT-PCR (Reverse Transcriptase Polymerase Chain Reaction) is the most frequently used molecular method. Knowledge about genetic control of maize virus resistance is the basis for development of successful breeding programmes concerning virosis suppression. Various types of molecular markers are used for mapping genes responsible for maize virus resistance. SSR (Simple Sequence Repeats) markers are the most suitable for this type of experiments. In this paper these methods will be described through the results for   MDMV ( Maize Dwarf Mosaic Virus), MSV (Maize streak virus) and identification of possible cause of maze redness syndrome.

EFFECT OF OSMOTIC STRESS ON MORPHOLOGY AND SOD ISOFORMS OF MAIZE ROOTS

 

Dragana Ignjatović-Micić, KsenijaMarković, Mirjana Vuletić, Violeta Anđelković, Vesna Lazić-Jančić

 

Drought is one of the most important abiotic stresses that seriously decreases final grain yield in maize. Since the occurrence of drought is not predictable, breeders have to produce maize hybrids able to withstand stress and have stable yield under various environments. Identification and measurement of secondary traits that contribute to grain yield under drought e.g. anthesis-silking interval (ASI), are the most important for that breeding strategy.Analyses of ASI were carried out on 130 maize genotypes from the crosses between DTP (Drought Tolerant Population) and two inbred lines from commercial ZP hybrids, A and B. Backcrosses (BC2) were sown in 2007 at two locations Zemun Polje and Skopje. Two genotypes with short (A1, B1), two with long (A2, B2) ASI from both crosses, as well as A and B lines, were chosen for further analysis in this study. The experiment was conducted under controlled conditions. One half of the plants (treatment) were grown on fresh aerated nutrient solution complemented with 4% PEG (polyethylene glycol, Mr 10000), while control plants were maintained on the nutrient solution without PEG.The response to PEG treatment of these genotypes was analyzed in respect to their root morphology and superoxide dismutase (SOD) activity. PEG treatment caused different levels of root growth reduction in analyzed genotypes. Investigation of the osmotic stress influence on maize SOD isoenzyme pattern revealed increased intensities of MnSOD isoenzymes in PEG treated-plants. Detailed discussion of the current results will be presented at the poster.

Institut za kukuruz „Zemun Polje“

 

Recognizing genetic similarities between inbred lines is important for parental choice, cross planning, line assortment into heterotic groups and tester choice. In this study genetic similarities of seven sister inbred maize lines derived from F2 generation was evaluated using RAPD markers. Total number of alleles identified with ten RAPD markers was 51. Number of bands detected with different primers was between 3 and 10, with the average number of alleles 5.1. Genetic similarity coefficients (Dice and Sokal and Michener) were calculated between the pairs of genotypes, on the basis of presence/absence of RAPD alleles. The Dice’s coefficient of similarity was in the range from 0.73 (between lines 1 and 4) to 0.91 (between lines 4 and 6).  The highest genetic similarity calculated according to Sokal and Michener was 0.88 (between lines 2 and 6), while the lowest was 0,66 (between lines 2 and 5). Cluster analyses using both coeffients grouped the analised maize sister lines in one cluster with two subclasters and two lines (1 and 2) loosely tied to the cluster. The first subcluster consisted of three, and the second of two inbred lines was performed using similarity matrices for both coefficients.

RAPD MARKER BASED CLUSTER ANALYSIS OF SOYBEAN GENOTYPES

 

Vesna Perić, Ana Nikolić, Snežana Mladenović Drinić

 

Institut za kukuruz „Zemun Polje“

 

In studies of genetic diversity of breeding materials different statistical methods are applied. Among them cluster analysis stands out as it does not demand an initial hypotesis regarding the probability distribution of the data and as it provides easy interpretation. Considering that the results of clustering can be influenced by the similarity coefficient choice, these coefficients need to be better understood so that the most efficient ones in each specific situation can be employed. The objective of this study was to investigate the influence of different similarity coefficients over the folowing cluster analysis, based on data from RAPD marker analysis of  soybean genotypes. Twenty soybean genotypes of different orgin were analysed with 27 RAPD markers. Genetic similarity estimates were obtained between each pair of genotypes using four similarity coefficints. The highest genetic similarity, by all four coefficients was between genotypes Kunitz and P 9272. The lowest genetic similarity was between Maple presto and P 9272 according Sorens-Dice and Maple presto and ZPS015 according Roger and Tanimoto coefficients.  UPGMA procedure based on each of the similarity coefficient assigned the twenty genotypes in two main clusters. Six genotypes were placed into the cluster I by all four methods. The structure of second cluster differs depending of coefficient of similarity.

POLLEN STAINING METHOD FOR POLLEN VIABILITY DETERMINATION IN CULTIVATED PLANT SPECIES

 

Jovanka Atlagić i Sreten Terzić

 

Institut za ratarstvo i povrtarstvo, Novi Sad

 

There are plenty of terms in literature that are used to describe pollen viability: fertility, vitality, germination, stainability etc. Different methods are used to study this important biological trait: staining (acetocarmine, potassium iodide, tetrazolium chloride etc.); estimation of pollen germination using different growth media; fluorescent microscopy for monitoring of germination and growth of the pollen tube, etc.The results shown in this paper imply a successful application of staining method by Alexander (1969) which is simplified in comparison to the original method and adapted for pollen viability estimation in sunflower, rapeseed, sugar beet, maize, wheat and alpha alpha. We described the aspects of research in which this method is most often used. Those are: interspecies hybridization, pollinator value, stability of CMS and fertility restoration, abiotic influences on fertilization. The method is simple and fast and although it gives a relative mark, it is applicable for fertility potential estimation.

The reaction of six commercial rapeseed (Brassica napus L.) cultivars to the increased Cd concentrations in vitro was tested. Cultivar seeds were sterilized and placed onto modified MS medium (Murashige and Skoog, 1962) supplemented with different Cd concentrations. Plants were grown at 21°C and at the 16:8 photoperiod (light : dark). Plant development was observed during two weeks of culture. After two weeks, dry and fresh matter of root and above-ground part of the plants were measured. In all tested genotypes, decrease in mass of root and above-ground part compared to the control (plants grown on MS medium without Cd) was observed.

There are only a few reports about the relationship between tissue culture and agronomic traits in wheat. In an attempt to enlarge the knowledge in this area, 96 wheat genotypes of worldwide origin were evaluated for their tissue culture response as well as the agronomic performance in the three-year field trials. Plant regeneration was achieved from immature embryos collected 12-15 days after anthesis. Associations between tissue culture and agronomic traits were surveyed by the correlation and path coefficient analyses. A trait-association by year biplot was applied to understand environmental effects on these relationships. All significant trait-associations were of a moderate magnitude and were responsive to the environment. The path coefficient analysis revealed that a grain yield had the highest positive direct effect on a callus formation while the kernel number per spike had the highest positive direct effect on regenerative calii and plant number per embryo. Nevertheless, only productive tillering had significant (positive) direct effect on all studied tissue culture traits.

The objective of this investigation was to determine a combined effect of sowing date, fertilizaton method, and irrigation on the number of emerged plants, root diameter, root mass, number of leaves, mass of above-ground parts, dry matter mass of root, and the percentage of dry matter of above-ground parts in the prevernal period of seed sugarbeet. Field trials were conducted in the agroecological region of southern Bačka in 2005, 2006, and 2007. The trials  were part of a seed plot which received the following treatmens: fertilization 35 kg N, 70 P O , 105 kg K O before basic tillage and control, sowing date 20 avgust and 10 septembar and irrigation before basic tillage and after sowing.The analysis of the data recorded indicated the presence of interactions beetween morphological characteristics of sugarbeet root mass, mass of above –ground parts, root diameter, number of leaves , dry matter mass of root and above-ground parts on one side and the first sowing date, fertilization before basic tillage, and irrigation after sowing on the other.Number of emerged plants depended primarily on sowing date. The first sowing date rendered 145-165000 plants/ha, the second 80-108000 plants/ha.

Poljoprivredni fakultet, Novi Sad

 

Vegetable production in greenhouse in Serbia is in the last few years importantly improved technologies of production. Seedlings production is improved too, using substrates, pots, and plastic containers with precise volume. The aim of this paper is to investigate influence of different substrate type and volume of containers on Cucurbitae sp. seedlings quality.            In all variation of substrate volume, the best values of morphological characteristics are measured in the biggest pots. The best seedlings quality was in pots with the smallest substrate volume. Regarding Cucurbita moschata, best results were achieved using substrate Stender A 280, substrate volume 1000 cm3, while in results with Lagenaria vulgaris show that for wide production is more suitable to use Klasmann Potground H substrate and containers of 300-cm3 volume. For gourd Lufa sp., it is recommended to use Klasmann Potground H substrate and 1000-cm3 containers volume.

Technological quality of four winter wheat cultivars (Ana Morava, Vizija, L-3027, and Perla), and two winter triticale cultivars (Favorit and Trijumf) in dependency of nitrogen nutrition and ecological factors were investigated. Nitrogen fertilizers are applied in 4 doses: N1= 60 kg N ha-1, N2= 90 kg N ha-1, and N3= 120 kg N ha-1. Analysis fo sedimentation, gluten content, and rheological flour and dough properties were done. The best protein and gluten quality have shown wheat cultivar Perla. In all of investigated genotypes sedimentation and gluten content increased with nitrogen increasing. The highest sedimentation value and gluten content established with application of 120 kg N ha-1. Cultivar Perla in average had the highest sedimentation value (45ml) and wet gluten content (39,4%) in N3 varijant. The triticale cultivars are reacted positively to nitrogen increasing. The highest sedimentation value (20ml) and wet gluten content (22,9%) had Trijumf in N3 varijant. The nitrogen application influenced significantly to rheological flour and dough quality. That influence was higher in wheat than in triticale, because wheat has higher genetic potential for quality. The highest quality increasing was in nitrogen application of  120 kg N ha-1, when in all cultivars increased quality number and quality group. The best rheological quality have shown Perla, which in average had quality on the level of A2 quality group. Quality of triticale was on the level of C2 quality group.

In this paper the the reaction of spring cultivars and genotypes to increased soil acidity as well influence of applyed CaCO3, NPK and organic fertilizer to  changes of chemical properties of soil and grain yield of cultivars were investigated. The application of fertilizers had positive effets to chemical changes of soil (decreased acidity and contents of Al, and increasing organic matter contents of soils and available forms of total nitrogen, ass well soil availabele phosphorus and potassium). All examined cultivars expressed the lowest grain yield on controls variant while grain yield on the fertilized variant was significantly higher. Small grains expressed different reaction to increased acidity of soil. The application of different fertilizers increased the grain yield of spring wheat by 2.8 times, in barley 4.0 times, in oats by 2.3 and in triticale, 2.4 times in average for all cultivars and treatments. The highest grain yield  was achieved by joint application of NPK, lime and manure.

The composition of pericarp essential oil, seed fatty oil, antioxidant and antimicrobial activity of laurel fruit, Laurus nobilis L., Lauraceae was investigated. Laurel fruit was collected from three trees in Herceg Novi. Pericarp essential oil and seed fatty oil were analysed by using gas chromatographic methods (GC/FID, GC/MSD). Pericarp (37.1–40.0% fruit) yielded 0.28-0.30% of essential oil. The main constituents were 1,8-Cineole (61.1-75.0%), 2-Udecanone (3.6-7.2%), α-Terpinolene (2.3-2.6%) and trans-β-Ocimene (0.6-6.4%). The seed contained 26.1-28.8% of fatty oil. Main fatty acids in all specimens were lauric acid (51.8-54.8%), oleic (16.9-18.0%) and linolic acid (14.5-16.9%). High content of lauric acid assorts the laurel semen oil in the oils of lauric type. There is a growing interest for the new sources of lauric acid, because of the high price of these oils. Methanol extract of pericarp (0.2% alkaloids, 2.8% tannins, 1.3 flavonoids) and fruit (0.2% alkaloids, 3.1% tannins, 0.7% flavonoids) showed low antioxidant activity (FRAP method, neutralization of DPPH radicals, inhibition of lipid peroxidation). Antimicrobial activity was investigated by diffusion method. Essential oil of pericarp showed antimicrobial effect at the concentration of 1.0 µl/disc. At the concentration of 5.0 µl/disc the growth of all bacterial strains (S. aureus, S. epidermidis, B. subtilis, P. aeruginosa, E. coli, S. cerevisiae) was inhibited. Laurel pericarp essential oil exhibited more pronounced antibacterial activity in the comparison with the laurel leaf essential oil.

Present in excessive amounts, micronutrient boron may limit wheat growth and yield. The aim of this study was to investigate the possible impact of high boron concentrations on Ca and K uptake in wheat genotypes differing in boron tolerance. The analysis was performed at seedling stage, on 9 promising NS wheat lines that were germinated and grown in the presence of boric acid, concentrations 0 (control), 50, 100 and 150 mg/l (treatments-B50, B100, B150). Significant differences among treatments were observed regarding B, Ca and K uptake. Both tolerant and susceptible genotypes accumulated less Ca and more K and B in conditions of excessive B supply than on control. Tolerant lines were characterized by higher Ca/B ratio on B150 treatment than the susceptible ones, which might imply the involvement of Ca in boron tolerance mechanism. K/B ratio was higher in conditions of normal B supply in group of susceptible genotypes. Further analyzes in both laboratory and field conditions are required to confirm the hypothesis that tolerant lines posses lower K requirements in conditions of normal boron supply.

The history of cereals in human nutrition is much older than bread. Cereals should be represented by about 60 % in food, in the form of flour made from integral grain. This can be achieved by the application of different technological procedures, and expanding is one of processes after which proteins, mineral and aromatic substances remain, which is a common denominator in nutrition by the utilisation of whole cereal grain.As energetic needs are concerned (kcal), the basic rule is to take in as much energy as it can be consumed daily. The ingestion of constitutive and protective substances depends on the age, body weight, gender and profession. The formulas presented by the US National Academy of Sciences were applied. Recommended daily doses (RDD), i.e. the intake of energy and certain nutrients for healthy adults are as follows: proteins 0.9 g / kg body weight; lipids 1.5 g / kg body weight; carbohydrates 4 g / kg body weight; water 40 ml /kg body weight; vitamin B6 1.0-1.3 (mg / day ); vitamin B12 1.8-2.4 (µg/day); folic acid 300-400  (µg/day).

The study of the tomato hybrid Gardel F1 was carried out through a field trial with irrigation in the area of Niš. Irrigation term was determined on the basis of soil humidity measurements by tensiometers, that were set at 35 cm under the ground. Irrigation was applied when tensiometers showed values of 25 kPa, 35 kPa, or 45 kPa, and it was stopped when that values reached 10 kPa. The highest tomato fruit yield was observed in the variant where soil capillary potential was kept between 10 kPa and 35 kPa, and the difference between that variant and the one with capillary potential kept in range 10-25 kPa was highly significant. A significant fruit yield increase was obtained in the variant with pre-irrigation soil humidity of 35 kPa comparing to the variant with pre-irrigation soil humidity of 45 kPa. Water demand, i.e. potential evapotranspiration, of the tomato hybrid Gardel F1 was also established, and in the conditions of southern Serbia it amounted 678.9 mm. On the basis of water consumption and fruit yield analysis, the highest water utilization efficiency (WUE) was observed at the variant with pre-irrigation soil humidity of 35 kPa.

A great distribution of acid soils throughout Serbia is one of limiting factors of the plant production. It is assumed that over 60% of soils in Serbia belong to a group of acid soils and that this percentage is permanently increasing. Considering that the majority of cultivated plants require slightly acid, neutral to alkaline reaction of the soil, a very small number of crops can tolerate an extremely acid reaction and conditions of these types of soils that have been gradually expanding. Soil acidity reduced yields of maize (Zea mays L.) up to 70% on 8 milion hectares in developing countries because maize is not acid soil–tolerant. Influence of liming to maize hybrids were investigated on experimental field of Agricultural College Kraljevo on the arable land (pseudogley) during the growing seasons 2003–2005. Liming had sigificant influence to increasing of yield of all maize hybrids, especially on NS 420, NS 510 and Zenit. The highest tolerance to unfavorable conditions of pseudogley was expressed hybrids: NS 540, NS 640, NS 6010 and Zenit while the lowest tolerance NS 542 hybrid. In dependance of liming the average increasing of yield of investigated maize hybrids varied in ratio 9.9% (NS 640) to 45.8% (NS 510).

The effects of eight sowing dates of the domestic cultivar funegreek on the yield, total germination and 100-seed weight were observed in the present study. The four-replicate trial was set up according to a randomised block design in Pančevo in 2007 and 2008. Sowing was done on eight dates: I (March 7), II (March 17), III (March 27), IV (April 7), V (April 17), VI (April 27), VII (May 7) and VIII (May 17). Harvested seed was dry down to 9% moisture, cleaned off all admixtures and then the yield was determined. Seed samples were drawn from each replicate for testing total germination and the100-seed weight. Seeds were germinated according to the ISTA Rules in a germination cabinet at the institute for Medicinal Plant Research "Dr Josif Pančić".According to the analysis of variance, all sowing dates very significantly affected all studied traits. The factor year was very important for the yield and total seed germination, while there were no significant effects on the 100-seed weight. The sowing date x year interaction was very important for total germination, while there were no significant differences in yields and 100-seed weights. The highest yield was obtained on the V and IV sowing dates, while the performed LSD test showed significant difference in relation to other sowing dates. The greatest germination and 100-seed weight were recorded in the seed of the fourth sowing date (April 7). Based on the two-year results, it can be concluded that the optimum dates for funegreek sowing in the location of Pančevo range from April 7 to April 17 (i.e. IV and V sowing dates).

In two years research, three different row spacing (25, 50 and 70 cm) and three sorts of soybean with different maturity group (Proteinka, Novosadjanka and Vojvodjanka) were investigated in irrigation conditions. Aim was to establish size of influence of row space on mass of 1000 soybean grains. Obtain data were arrange by variance analysis – method two factorial split-plot experiment.  Investigated factors: sorts (large plot) and row space (under plot) (Hadživuković, 1991). Average mass of 1000 grains for both years was 171.31 g. In 2003 mass was lower because of undesirable weather conditions and attack of Helicoverpa armigera Hubn (152.77 g), but in 2004 was 189.95 g. Mass of 1000 grains is sort’s attribute.  Significantly lower mass had sort Vojvodjanka (11.59 to 12.36%) comparing with Proteinka and Novosadjanka. Increasing of row space showed also increase of mass of 1000 grains, but not significantly. It was established positive correlation between 1000 grains mass and yield per plant.

The investigation was carried out with the aim valuating nitrogen nutrition efficiency of different wheat cultivars in various sowing density by grain yield aspect. The identification of cultivars yielding in conditions of less amount of available nitrogen is very important because of their including in wheat breeding, but it has practical importance, too, improving rationality of wheat production. Three newer wheat cultivars: Ana Morava, Perla and Vizija, selected in Small Grain Research Center in Kragujevac, were included in investigation. There were two sowing rates: G1 500 kernels/m2 and G2 650 kernels/m2. Three variants  of nitrogen nutrition were applied: N1 60 kgN/ha, N2 90 kgN/ha and N3 120 kgN/ha. The grain yield were calculated per plot (5m2) and expressed as t/ha. The two – years results show differences in grain yield depending on added nitrogen amount, especeally between first and second, while differences between second and third nutrition level were not statistically important. The yield differences, affected by various sowing density, were more expressed. The studied cultivars showed better uptaking and utilization efficiency in G2 sowing variant. Wheat cultivar Vizija obtained grain yield in G1 almost the same as in G2 sowing variant.

Aim of this work was to estimate effect of crop density on relationship between grain yield per plant and some agronomic traits in maize (plant height, ear height, leaf number, number of lodged plants, ear length, kernels per row, number of kernels per ear, cob weigh, ear diameter).Field plots were set up with three maize hybrids (ZP 684, NS 6010 and Dijamant – 6) in three crop densities (50.000, 60.000 and 70.000 plants per hectare).Correlation coefficients were calculated on two ways, using values of traits for 1) three hybrids as an average from three crop densities, 2) three crop densities as an average from all maize hybrids.For both calculations, similarity between correlation coefficients was estimated, with exception for two traits: ear length and cob weigh. According to the first type of calculation, grain yield per plant was in very strong positive correlation with ear length (rgy-el = 0,979) and in strong negative correlation with cob weigh (rgy-cw = -0,642). According to the second type of calculation, values and direction of correlation coefficients were changed, so that rgy-cw = -0,814 and rgy-el = 0,998.This result shows that application of agricultural measures can significantly affect the relationship among some traits of maize genotypes.

Results on the long-term scientific and research activities on the improvement of maize utilisation are presented in this paper. The studies were performed at the Department of Technology of the Maize Research Institute, Zemun Polje, which is the only scientific institution in our country in which overall studies with the aim to improve utilisation of field crops have been carried out for several decades. These studies encompass three main fields such as quality of grain, silage and the development of new products. The associates of the Department of Technology have published almost 400 scientific papers and presentations, monographs, project analyses and books. The aim of the present study was to analyse chemical composition, physical and technological properties, that is, grain usability of the most widely grown ZP maize hybrids of different maturity groups and various types of the endosperm. It was determined that genetic variability of ZP hybrids provides a broad scope of the most different qualitative traits in the application and technological processing of maize due to which numerous products for different purposes can be made.

Essential oils are present in the tobacco leaf and are a source of the characteristic aroma and taste of the plant itself. These oils are a complex mixture of carbohydrates, alcohol, carbonyl compounds and mercaptan and other compounds of aliphatic, aromatic, alicyclic and heterocyclic structure.Depending on insertion, the amount of essential oils (w/w) in oriental tobacco types of the local origin ranges from 0.09 % to 0.07 %. This difference is even more pronounced in semi-oriental tobacco types and ranges from 0.06 % to 0.14 %.

An experimental study, aimed to establish the effect of sowing mode on seed yield and quality of alfalfa cultivar Zaječarska-83 was carried out in a suburb of Niš.  Highest seed yield was reached with the inter-row distance of 40 cm (330 kg ha-1) and the lowest one with the distance of 60 cm (275,6  kg ha-1). Annual weather conditions had a significant effect on seed yield. So seed yield ranged by year from 187,2 kg ha-1 (sowing year) to 460,1 kg ha-1 (3rd year).The best seed quality was observed when inter-row distance was 60 cm. Highest mass of 1000 seeds was obtained with the inter-row distance of 60 cm (2,08 g) and the lowest one with the distance of 20 cm (2,03 g). The lowest content of hard seeds was obtained with the inter-row distance of 60 cm too (7,8%) and highest with the distance 20 cm (9,9%). The highest shooting potential was obtained with the inter-row distance of 60 cm (89,1% ) and the lowest one with the distance of 20 cm (86,4%).

 Institut za kukuruz „Zemun Polje“, Zemun Polje

 

In order to observe the effects of a biodegradable Super-Hydro-grow polymer, which retains moisture in the soil, the trial with two maize hybrids and their parental inbreds was set up under dry land farming and irrigation conditions in 2006 and 2007.The greatest fresh mass was recorded in the 4-8-leaf stages under irrigation during 2006. It was on the average higher by 30% and 40% than in relation to SHG, i.e. dry land farming, respectively. On the other hand, in 2007, a very arid year, the effects of SHG were better, i.e. the average fresh mass was higher by 31% in relation to conditions of both, irrigation and dry land farming. The dry mass content insignificantly varied over treatments, but in 2007 it was twice as little as in 2006.In the flowering stage, the fresh leaf mass was on the average greater by 10% in the SHG treatment than in any other treatment in 2006, and by 17%  in the treatment with irrigation in 2007. There were no other significant deviations in the dry mass content. In relation to the yield, there were no differences between SHG and irrigation treatments in 2006, while the 2007 yield obtained in the SHG treatment was higher by 18% and 35% in irrigation and dry land farming, respectively. The application of the SHG polymers in the maize production provides a normal growth, development and formation, what is especially important during dry seasons.

The effect of locations and applications of different types of fertilisers on yield and seed quality of the marigold cultivar "domaći oranž"/"domestic orange" was observed and analysed during two growing seasons (2006 and 2007). The studies were carried out in the Zlatibor region (Gorobilje and Arilje) and in the region of southern Banat in the vicinity of Pančevo (Kačarevo). Three variants of fertilising were applied in these locations during both years of investigation: 1. 200 kg KAN ha-1, 2. 400 kg NPK (15:15:15) ha-1 and 3. control (without fertilising). The four-replicate trials were set up according to a randomised block design with the elementary plot size of 20 m2. Sowing was done in the optimum period (the third decade of April) and with the appropriate amount of seeds (8 kg ha-1). All necessary measures of protections against harmful organisms were applied during the growing season. Harvest was done at the stage of full maturity. According to obtained results the effect of locations on the seed yield was significant. The highest, i.e. lowest yield over all variants and both years of investigation was registered in Kačarevo, i.e. Gorobilje, respectively. The effect of fertilising on the yield in comparison with control was also significant. The highest quality of seed (germination viability, total germination and seed weigt) was recorded in the location of Kačarevo where NPK was applied, while the lowest quality of seed was identified in the location of Gorobilje where KAN was applied. The yield in 2006 was insignificantly higher over all locations and variants, which was caused by a greater amount of precipitation, but seed quality was somewhat better in 2007 as a result of a greater temperature sum.

Over long time researching for yeast microflore in Yeast industry, Beer industry, Milk industry and Meet industry in Macedonia, we have determined the most seldom species of yeasts in these industries. Researches began in 1971, firstly in Beer and Yeast industry, and later, in Meet and Milk industries. At the base of these researches, we have found that the most seldom species of yeasts are determined in three families and 20 species.           The researches were made in the period of 1971 - 2006 in Macedonia. Microbiological yeast cultures are isolated at Sabaurd agar and identification was made according Loder and Van Rij, 1965.According these researches, we have found the following yeast species which are determined in three families: Endomycetaceae, Sporobolomycetaceae, Cryptococcaceae. These yeasts have important role in mentioned industries, because some of them are growing up as the basic microbiological cultures for uses in industrial technologies, and of the other side, these yeasts could be contaminants or “wild yeasts”, which lowing the products quality. Most of the yeasts produced CO2 and alcohol, and the others are obviously or facultative infective for people or domestic animals. First of all, these are yeasts which are determined in Candida genus. The rest isolated species and subspecies are: S. cerevisiae var. elipsoideus, S. carlsbergensis, S. pastorianus, S. kefir, S. lactis, S. rouxi Boutroux, Pichia sp. Hansenula anomala, Kloekeria apiculata, Debaromyces, Torulopsis itd.
