THE SIGNIFICANCE OF PLANT GENE BANKS FOR BREEDING
by
PENČIĆ M., DUMANOVIĆ J., RADOVIĆ GORDANA AND JELOVAC G.
SUMMARY
The plant gene banks are one of the methods to maintain genetic resources. These banks are the essential and the most reliable maintenance; of crop genetic variability. Due to expensive facilities and infrastructure, the banks usually maintain a basic collection for a long-term period. Therefore, handling accessions in gene banks in a very responsible work based on scientific and technological principles.
The plant breeders mostly use their own collections which predominately consist of the elite germplasm.
Gene banks maintaining wild species, wild relatives of crops, old land races and populations and old commercial cultivars are the most precious source of genetic variability, necessary for a long-term scientific programme of plant breeding.
The plant breeders can benefit from gene banks only if their collection is utterly described and classified with a complete and accurate documentation and an easy accessible and efficient information system.
Although methods and tools used by plant breeders today are very efficient, this statement is not applicable to the level of information on genetic variability within a species. Also, this information is insufficiently used.
Keywords: plant gene bank, genetical variability, prebreeding, sistem for information

GENETIC MANIPULATION OF SUGAR BEET
by
MEZEI S., NAGL N., KOVAČEV I.
SUMMARY
Genetic engineering could be defined as transport of isolated DNA from one species to another. It makes possible exchange of genetic information between species, expending the genetic variability and increasing the yield and quality of crop species. Genetic transformations of sugar beet were obtained by direct and indirect gene introduction. Results of these research depended upon used methods, genotypes and morphogenic potential of transformed plant material. It is not exactly known the place of attachment of introduced genes and number of copies of introduced DNA sequence. The recent advances in molecular biology techniques enabled the analysis of genetic variability on DNA level, and creation of linkage maps, i.e. graphical presentation of area of loci. The purposes of linkage maps are: identification of genotype, mapping in order to mark genes to agronomic important traits and gene isolation.

KREMNA, SEMI DWARF WINTER WHEAT VARIETY
by
MIŠIĆ T., MLADENOV N.
SUMMARY
The winter wheat breeding program of the Institute of Field and Vegetable Crops in Novi Sad places emphasis on short straw and its increased resistance to lodging. These targets are achieved by means of Rht genes as well as genes from other sources of resistance to lodging. Several semi-dwarf and dwarf varieties have been developed by crossing genetically divergent and highly productive parents. These varieties successfully combine genes that confer a high genetic potential for grain yield, very good to excellent technological quality, resistance to lodging, diseases and low temperature, resistance to high temperature and air drought at the stage of grain filling with different times of maturity. The paper reviews the characteristics of the variety Kremna.
Kremna was released by the Federal Commission for Varietal Approval in 1995. It was made by crossing genetically divergent and highly productive parents. Its lineage includes the lines NS 2983, NS 3000, Rana niska, NS 2853 and ZG 1-628/77 (breeders: T Misic, Z. Jerkovic. R. Jevtic and M. Pribakovic). The spike is white and smooth, awnless, with 19-24 spikelets; the grain in vitreous and dark red (Triticum acstivum L. ssp vulgare var. lutescens).
Kremna is a semi-dwarf variety with the average straw height of about 75 cm, with excellent resistance to lodging. It is a medium early variety with very good resistance to low temperature. Its resistance to leaf rust (Pucc, recondita tritici) is excellent, the resistance to stem rust (Pucc, greminis tritici) and powdery mildew (Erysiphe graminis tritici) is good. A distinctive feature of the variety is a long duration of leaf green area and a prolonged period of photosynthetic activity (table 4). The resistance to cereal leaf beetle (Lema melanopus) is medium to satisfactory. A distinguished feature of the variety is very good resistance to high air temperature and air drought at the stage of grain filling. As it has a narrow and a relatively short leaf, it may be considered as fairly economic regarding its requirements for nutrients and water. The mass of 1000 grains is about 43 g, volumic mass 85-89 kg/ha. The variety is classified in the quality subgroups A2-Aj. The milling and baking quality is excellent. The content of dry gluten in about 11%. According to the indicators of technological quality, the variety is classified in the II-I technological group as an excellent bread variety (table 2). The variety is productive, with the genetic potential for grain yield between 11 and 12 t/ha (tables 1 and 3). The variety is adaptable and suitable for growing in soils of various fertility levels and in different production conditions. The seeding rate is 550-600 variable seeds per 1 m2, to secure the stand at harvest of 700-800 spikes per 1 m2.
A successful combination of genes responsible for important characteristics makes the variety Kremna a unique and important genotype for a profitable production at a high level of intensity.

PEPPER GROWING
by
GVOZDENOVIĆ D., TAKAČ A.
SUMMARY
Pepper is one of the most significant vegetable species for its high nutritive and biological value, as well as for its multiple ways of usage in human nutrition and processing industry.
Vegetable pepper is used at its technological and physiological maturity in fresh or processed forms, while industrial pepper is used for production of powder pepper. Pepper fruit: is rich in carbon hydrates, high oil content, it contains apple and lemon acids, and colored matters. It is especially rich in vitamin C and vitamins belonging to B group. Its spiciness originates from alkaloid capsaicin which is most often found in nerves of fruit and in seed, and rarely in pericarp. It is most often produced from seedlings in the opened field and in the protected areas, or directly from seed sowing.
Keywords: pepper, production, sowing, harvesting

TOMATO GROWING
by
TAKAČ A., GVOZDENOVIĆ D.
SUMMARY
Tomato is widely used in human nutrition either as fresh raped fruit or as different manufactured products. In SRY it is high railing in sowing vegetable structure with approximately 22.000 ha. It’s grown from seedlings for glasshouse, plastic house and early field productions, and 1'rom direct seed sowing for industrial manufacturing. Under our conditions tomato is most often sown from March the 15th to April the 1st. (average early production) with fruit ready to he harvested from June the 1st to July the 30th. For this purpose hybrids such as NS-2, NS-6, Mi-10, Arleta etc., are exclusively used. The significant role in seed production is played by direct sowing. For this purpose determinant varieties with firm fruit and mutual ripening such as Novosadski niski, Arizona, Mobil, Narvik etc., are used. For late autumn usage late tomato sowing and ripening in chambers or in basements are used.

USE OF CALLUS CULTURE IN SELECTION OF WHEAT GENOTYPES TOLERANT TO HIGH SALT (NaCl) CONCENTRATIONS
by
ŠESEK S., KONDIĆ ANKICA
SUMMARY
Wheat (Triticum aestivurn L.) tolerance to high salt (NaCl) concentrations has been studied by the method of in vitro culture of mature embryos. The embryos were isolated from air dry grains of the high-yielding winter wheat varieties Balkan and Renesansa. After isolation, the embryos were inoculated onto a modified MS (Murashige and Skoog, 1962) induction medium and kept on it for 30 days. The embryogenic calli thus formed were transferred to a medium with the identical mineralogical composition lo which five different NaCl concentrations (1%, 1.5%, 2%, 2.5%, 3%) had been added. The obtained results showed that the number of survived calli and green regenerants, of both genotypes, decreased in proportion with the increase of NaCl concentration in the medium. In the case of the genotype Renesansa, 72.7% of the calli, in relation to the control, survived the lowest concentration (1% NaCl). The percentages dropped sharply with the increases in sail concentration, to reach 22.7% with the concentration of 3% NaCl. The genotype Balkan exhibited a higher tolerance to the first three NaCl concentrations (65%, 70% and 65% of survived calli with the concentrations of 1%, 1.5% and 2% NaCl, respectively), the percentages dropping sharply only with the high concentrations (35% with the concentration of 3% NaCl). The regenerants of both genotypes were more sensitive to high NaCl concentrations than the calli. Not a single regenerant of both genotypes managed to survive the NaCl concentration of 3%.

by
STOJANOVIĆ S., STOJANOVIĆ JOVANKA, JERKOVIĆ Z., JEVTIĆ R., GUDŽIĆ S.
SUMMARY
The barley leaf rust, caused by biotrophic fungus Puccinia hordei Otth, is one of the most important diseases in Yugoslavia. In this paper resistance of 14 winter and 12 spring barley new lines in 1995, and 18 winter and 16 spring lines in 1996 was investigated.
The obtained results demonstrated that most of the barley lines were susceptible to leaf rust, but some of them were resistant. The most resistant in 1995 were winter lines 2, 4, 5, 6, 7, 14 and spring ones 3, 5, 8, 9. In 1996 the most resistant were winter line 3, 5, 6, 7, 14, 15, 16, 17 and spring ones 5, 6, 10, 11, 12.
The mean coefficient of infection in 1995 was higher on spring and in 1996 on winter barley lines.

THE HOMOGENEOUS OF SEED ACCORDING TO WHEAT STORAGE PROTEIN COMPOSITION
by
JESTROVIĆ ZORICA, KNEŽEVIĆ D., GRUJIĆ VESNA, UROŠEVIĆ D.
SUMMARY
The acid PAGE electrophoresis was used for analysis gliadin content for 9 genotypes of winter wheat. Differences between genotypes were found according to number of protein bands, relative mobilities and color intensities. The number of gliadin components for one genotype variated between 20 and 26. The number of different gliadin components for all analyzed genotypes was 68. Genetic homogeneous of analyzed genotypes was evaluated by identical composition of gliadin components. Identical electrophoregrams were found in 7 genotypes, except for L-6/1046 and L-17/6. The 25 different alleles on six GLD loci were determined: 5 at the GLD 1A, 5 at the GLD IB, 3 at the GLD ID, 3 at the GLD 6A, 5 at the GLD 6B and 4 alleles at the GLD 6D locus.
Key words: Wheat, genotype, electrophoresis, gliadin

PREHARVEST SPROUTING OF DIFFERENT WHEAT CIJLTIVARS
by
STOJANOVIĆ JOVANKA, STOJANOVIĆ S., ĐOKIĆ D., LOMOVIĆ S., PEROVIĆ D.
SUMMARY
To determine the amount of genotypic variation for tolerance to preharvest sprouting, the effect of different temperature on percentage of germinated grains in the spike was investigated on 34 cultivars during 3 year. Wheat cultivars were grown in field conditions. At maturity whole spikes were harvested and after drying were artificially weathered. The number of sprouted and nonsprouted kernels in each spike was determined after 12 days of weathering and percentage of sprouted in relation to total grains in the spikes was calculated.
The obtained results demonstrate the presence of genotypic differences to preharvest sprouting. The lowest percentage of sprouted grains for all years and temperatures was at cultivars Florida 302, Evropa, Francuska, Sava and breeding line Kg-A21. These varieties and ones with low percentage of germination from 20 °C as Yugoslavia, Zemunka and Lasta may be used as a donors of preharvest sprouting tolerance. Comparison of cultivars has not established a degree of correlation between presence or absence of awns and kernel color on amount of sprouting.
Temperature had the significant effect on the level of sprouting. In the average for all cultivars on 10 °C percent of sprouted grains was 73 in 1994 and 85 in 1995 years. On 20 °C these are 42 and 53% in the 1994 and 1995 respectively, and 36 in 1996 at room temperature.

PILOT TEST - AN AMENDMENT TO THE FIELD AND LABORATORY METHOD OF WHEAT TESTING FOR RESISTANCE TO LOW TEMPERATURE
by
HRISTOV N., MIŠIĆ T, MLADENOV N.
SUMMARY
Resistance to low temperature is a complex characteristics which depends on genotype and environmental ['actors. Because agroecological conditions which vary from one year to another change the level of hardening, it is necessary to determine a treatment for testing the insistence to low temperature. In a pilot test, wheat plants are subjected to a cold stress, by gradually lowering the temperature to -15 °C over the time intervals varying from 10 to 70 hours. Based on the reaction of the tested plants - deterioration of leaf area and tillering nodes - it is possible to determine the optimum period for exposing plants to low temperatures (a mild and a harsh treatment) in order to successfully differentiate genotypes for the level of resistance to low temperature. For the sake of efficiency of the field and laboratory method, it is necessary to run pilot tests each year, because placing plants into cold chambers. The paper presents three-year results of the pilot test which included three varieties which differ in the level of resistance: Partizanka (excellent resistance), Yugoslavia (almost very good resistance) and Novosadska rana 2 (good resistance).
Key words: wheat, cold stress, low temperature resistance

by
STANČIĆ I., NIKOLIĆ Z., VESELINOVIĆ Z., ŽIVIĆ JELICA
SUMMARY
The paper presents the results of investigation on combining abilities of parents by analysis for the mode of inheritance yield components of fi generation diploids hybrids in sugar beet. The parental material included: five maternal components (two CMS lines, three CMS hybrids maternal) and three diploid polygerm populations. The parental genotypes and fj hybrids were investigated during the year 1995 on two locations Aleksinac and Novi Sad. The following characters were assessed: root yield, sugar content and crystal sugar yield. On the basis of the results it can be concluded that heterosis of the better parent was expressed for root yield and crystal sugar yield, while intermediary and the dominance mode of inheritance were presents on one of the parents for sugar content. The general (GCA) and specific (SCA) combining abilities parental genotypes was determined by statistics method of line x tester. The dominant component of genotypic variance was larger additive for the yield components.

by
MARTINOSKI Đ., JANKULOVSKI D., AGIĆ RUKIE
SUMMARY
Several populations and lines of onion (Allium cepa L.) were examined regarding the seed yield components, compared to the method of pollination. The plants have been isolated from outside influence and two methods of pollination were applied: mechanical and by insects, the control variant was pollinated without any intervention.
Pollination by insects gave the best results. Larger number of fertile flowers resulted in higher absolute seed mass. The yield in the variant pollinated by insects was 25.74% than the seed yield of the variant pollinated by mechanical method and 44.38% more than the control.
Key words: onion, pollination, yield components, yield

EVALUATION OF HETEROSIS FOR YIELD AND COMPONENTS OF YIELD IN INTERVARIETAL CROSSES OF PEPPER (Capsicum annuum L.)
by
ZEČEVIĆ B., STEVANOVIĆ D.
SUMMARY
By applying diallel crossings of six divergent pepper cultivars, we evaluated the degree of heterosis of the most important agricultural features. This investigation comprised three pepper cultivars of ssp. macrocarpum (Palanačka babura, Mačvanka and Palanačka kapija) and three cultivars of ssp. microcarpum (Kobra, Romana and Feferona žuta ljuta). The crossings, excluding reciprocal ones, were performed in 1994 and the next year all the fifteen hybrids together with their parents were planted applying the complete random block system in four replications. Heterosis was recorded for all features: earliness, fruit length and yield per plant. The most promising crossing combinations where the highest stage of heterosis was registered are: for number fruits per plant - Palanačka kapija x Romana, for fruit weight - Kobra x Romana and for yield per plant - Palanačka babura x Feferona žuta ljuta (67.5%). Regarding all investigated features it could be concluded that hybrid Palanačka babura x Feferona žuta ljuta is the most perspective.
Key words: pepper, heterosis, diallel crossing, yield

by
MARKOVIĆ Z.; ZDRAVKOVIĆ JASMINA, DAMJANOVIĆ M., ĐORĐEVIĆ R.
SUMMARY
The genetic activities on improvement of early tomato hybrids in Center for Vegetable Crops in Smederevska Palanka have been directed to constitute tomato hybrids of high fruit quality for fresh market production. New tomato F1 hybrids Atina and Golden Jubilee have been chosen. Hybrid Atina come from crossing between lines SP-93/16 and SPV-HK), and hybrid Golden Jubilee come from crossing between lines SP-91/10 and SPS-31. Parental lines of these hybrids have been obtained from many years of selection by pedigree method. The firmness of fruits comes from crossing of American cultivars and domestic lines. The agronomic trials have been carried outdoor in the field and in the plastic houses. Both hybrids showed good fructification, constant high productivity (2.5-3.0 kg/plant), high fruit firmness, prolonged storage and they are suitable for early productions in open and protected crops. Hybrid Atina F1 has sp+ habit, excellent setting, large and regular fruits (160 g) without greenback and VF resistance. Hybrid Golden Jubilee F1 has sp+ habit, large, regular fruits (200-220 g) with light greenback, VFN resistance and tolerance to late blight. Both hybrids are in official variety trials for commercial registration.
Key words: variety model, F1 tomato hybrids, tolerance to diseases

DRYING TOMATO SEED AIMED AT OBTAINING SEED OF HIGHER QUALITY
by
ZDRAVKOVIĆ JASMINA, TODOROVIĆ VESNA, MARKOVIĆ Ž., STEVANOVIĆ D.
SUMMARY
Poor germination was recorded in some tomato genotypes where the seed had been produced by a standard ethnology of additional processing. By applying a standard technology of additional seed processing, the seed germination in Narvik SPF cultivar was readily initiated, but was immediately distressed in the acid pulp medium. If not in the pulp, the seed was distressed in the additional processing when drying. We assumed that the problem was either the pulp quality or the duration of pulp fermentation. The pulp obtained from four groups tomato (mature, green, rotten and standard or control pulp obtained from the additional seed processing) fermented in eight terms (20, 28, 44, 52, 68, 76, 92 and 100 hours) simulating the actual additional seed processing. The best germination (99%) was recorded in green fruits which fermented in their own pulp for 28 hours. There were no significant differences in the percentage of germination between control, mature or green fruit pulp, whereas we recorded significantly lower germination (56%, 44 fermentation hours) in the rotten fruit pulp.

by
STANKOVIĆ R., MEDIĆ SUNČICA
SUMMARY
Unfavorable external conditions as well as pesticides applied at the time of harvesting can decrease seed germination and plant emerging. The aim of our investigation was to investigate the effects of insecticides on treated sunflower and corn seed. The results of the influence of the following insecticides: carbofuran, carbosulfan, imidakloprid and furatio-karb on seed capacity and seed germination are given. Carbofuran in all testing variants showed significant decrease of corn and sunflower germination. Carbosulfan, imidakloprid and furatiokarb applied prior to sowing did not significantly decrease the germination. However as the storage time was prolonged their toxic influence was increased.

by
BUKVIĆ BRANKA, VULIĆ BORISLAV, RADIN MILIVOJ
SUMMARY
Seed and planting material has an important role in plant production as the variety, or hybrid, choice is the first step in producing customer satisfying agricultural product. Seed for agriculture production is obtained by seed processors so its role in customer - supplier chain of a quality loop may be of crucial influence on product quality. Because of that, seed processors must develop quality assurance system. Series of international standards ISO 9000 offers proficient model for achieving necessary quality level. Existing quality assurance systems are not good enough and do need improvement, minimum of which may be bringing into accordance with ISO 9000 requirements.
Key words: quality assurance, dependability, seed processor
