GINOGENESIS AND DEVELOPMENT OF INBRED LINES OF SUGAR BEET IN VITRO
By
MEZEI SNEŽANA, KOVAČEV L.
This study was conducted to analyze the effects of genotypes on process of ginogenesis in vitro Donors of ovaries were plants flowering in the field in 1992. After sterilization ovules were excised and inoculated on medium with 0,5 ,μM NAA and 4,4 μM BA.
Ploidy level frequencies were determined in untreated control and treated samples by chromosome counts. Cytogenetic analyzes showed a wide range in somatic chromosome number. Explants of apical meristems were fixed for one day in Carnoy solution. Smears of meristems cells were stained in acetic carmine. Ten well spread cells were selected for chromosome counts in metaphase of mitosis.
Haploid, diploid, tetraploid and mixoploid plants were regenerated from un-pollinated ovule of sugar beet. By colchicines treatment, plant with significant doubled chromosome numbers were obtained in the genotype 3071/412.

POSIBILITY OF SHORTENINING BREEDING CYCLE OF SUNFLOWER VIA
EMBRYO CULTURE
By
VASIĆ DRAGANA, VASILJEVIĆ LJ.
SUMMARY
Seventeen days old embryos of sunflower inbreds CMS-V-8931-3-4, L-4, L-15, OCMS-2, BCPL and SNRF were sterilized and placed on MS medium supplemented with 0,1 mgl-1 IAA, 0,1 mgl-1 BAP and 500 mgl-1 casein hydrolisate. The embryos germinated and gave rise to plantlets. Plantlets with well developed cotyledons were transferred into Jiffy-7 vessels and, after successful acclimatization, planted in a green house. High percentage of viable plants was obtained. They were lower and they had smaller size of flower heads than field grown plants. They flowered earlier and their vegetation was about three weeks shorter. This method can help to shorten germination time and therefore can be profitably used in sunflower breeding programs.

GENETIC ANALYSIS FOR KERNEL WEIGHT PER PRIMARY SPIKE
IN WHEAT (Triticum aestivum L.)
By
PAVLOVIĆ M, KUBUROVIĆ M, KNEŽEVIĆ D.
SUMMARY
The diallel cross excluding reciprocals of four divergent wheat was performed and F1 and F2 hybrids were derived. These four cultivars and f1 and F2 hybrids were studied to evaluate the mode of inheritance, gene effects and combining ability for kernel weight per primary spike in wheat plants. The obtained results showed different modes of inheritance for kernel weight (intermediate, partial dominance, dominance and overdominance). Analysis of variance of combining ability indicated significant differences for this trait. The best general combiner for kernel weight was KG-75 cultivar while KG-75 x NS-322 was the best specific combiner.

GRASS SEED PRODUCTION IN THE HILLY AND MOUNTAINOUS REGIONS
OF SERBIA
By
TOMIĆ ZORICA, MLADENOVIĆ R.
SUMMARY
In 1990-1992 the effect of sowing and fertilization on grain yield of domestic perennial grass varieties has been studied in the hilly and mountainous regions of Kopaonik at the altitude of 1100 m. The highest grain yield was registered for the cocksfoot variety K-6 in the third experimental year and was 3-year average at the sowing rate of 545 kg and NPK application in the ratio 120:60:60 kg ha-1, respectively, in a box experiment (40 x 40 cm).
In the second experimental year, the highest grain yield (610 kg ha-1) was reported for the Timothy grass variety K-15 at the sowing distance of 40 cm and NPK application in the ratio 100:50:50 kg ha-1 respectively. However, the highest grain yield was registered already in the first experimental year with the red fescue variety K-14. Its 3-year average was 642 kg ha-1 at the sowing distance of 15 cm and NPK application in the ratio 80:50:50 kg ha-1 respectively.
In the hilly and mountainous regions of Serbia seed production may be expected to be improved because the grain yields reported, showed little differences compared to those from the lowland regions.

THE EFFECT OF SEEDLING ROOT SYSTEM DEVELOPMENT OF SOME
MAIZE PARENTAL COMPONENTS ON EMERGENCY AND SURVIVING
UNDER FIELD CONDITIONS
By
VESKOVIĆ M., POPOVIĆ RADMILA, MIRIĆ M., ĐUKANOVIĆ LANA
SUMMARY
On the occasion of establishing stock seed quality of parental components of hybrid maize, the occurrence of abnormal seedlings is noticeable. This occurrence is manifested by under grown primary root system and poorly developed secondary root with simultaneous plumule strong development of this seedling which is, according to accepted rules, evaluated and classified into abnormal seedlings. The purpose of this study was to establish the behavior of this type of seedling in the field trial, i.e. in the growth, vegetation and grain formation.

EFFECTS OF ECOLOGIC FACTORS, GENOTYPE AND HARVESTING TIME ON SUNFLOWER GERMINATION DURING STORING
By
CRNOBARAC J., MARINKOVIĆ B.
SUMMARY
Long vitality of oil plant seeds is particularly important because of maintenance of the germ bank. Sunflower for seed production was sown in field and greenhouse and female components of the hybrids NS-H-26 and NS-H-27 and the variety VNIIMK-8931 were harvested each third day, beginning from the 10th to 52nd day from the beginning of flowering. Seed germination was tested in rolled filter paper, according to JUS each 6th month, up to the 42nd month from the beginning of harvest.
According to the F-test, all studied factors showed significant effect. Date of harvest had significant effect, and participated with 74,85% in total variability, storing period with 14,55%, while agroecological environment and genotype participated with 0,2% and 0,02%, respectively. Ontogenetically young seed has short lifetime and vice versa. The seed harvested up to the 19th day from the beginning of flowering linearly lost its germination during storing and after 6 months its germination rate was below 90%. In all harvests, 22 days after the beginning of flowering, germination stagnated at the level of 90-100% and after 18 months it decreased, while in the harvests 34 days after the beginning of flowering this decreasing was observed after 36 months. The germination decreased in all variants below 90% after storing longer than 3 years. During the storing of 30 months, the seed produced in greenhouse and harvested from the 22nd to 40th day from the beginning of flowering had higher germination rate than the seed produced in field. Significant differences were observed among genotypes with respect to seed germination after storing of the 30 months.

SEED DORMANCY PERIOD OF TRITICUM DURUM WINTER VARIETIES
By
MLADENOVSKI T.
SUMMARY
The goal of this research was to determinate the duration of seed dormancy period of the winter Triticum durum varieties, derived at the Agricultural Institute, Skopje. Six varieties were included in the research: Milenka, Iva, Skopska rana, Durumka, Tina and Taga. The longest dormancy period have the varieties: Milenka - 77 days, then Iva, and Skopska rana - 63 days. All the varieties mentioned above have long dormancy period (more than 60 days). The varieties Durumka, Tina and Taga have dormancy period between 49 and 56 days and therefore they belong to the semi-long dormancy period group (10-60 days). None of the examined varieties have dormancy period shorter than 10 days. Achieved results show that examined varieties have different duration of dormancy period, which is determined by the inheritance factors of each examined variety.

NITROGEN ASSIMILATION ENZYMES IN MAIZE SEEDLINGS
By
HADŽI-TAŠKOVIĆ ŠUKALOVIĆ VESNA
SUMMARY
The activity of glutamate dehydrogenase (EC 1.4.1.3) and glutamine synthetase (EC 6.3.1.2) in seedling parts of maize genotypes, differing in endosperm storage protein content, was investigated. Reassimilation of NH4+ was intensive in scutellum, via GS. Both GS and GDH were involved in NH4+ assimilation. In growing axis GDH had a leading role in root tissue, but not in shoot tissue. As for genotypic differences, GS activities were similar in root and shoot tissue of all investigated maize genotypes germinated on water. Differences in GDH activities were evident and dependent on zein hydrolysis rate.

MULTIYEAR TESTING OF EFFECTS OF AGROECOLOGICAL CONDITIONS ON THE VARIABILITY OF QUALITATIVE PROPERTIES OF LUCERNE SEED
OF VARIETY OS-66
By
B. RAĐENOVIĆ
SUMMARY
The results of our five-year tests indicate that the highest germinability was achieved in 1988 - 64.5% and 1990 - 61.5%. The years 1987,1988 and 1989 gave an even germinability: 1987 - 53.3%, 1988 - 50.55% and 1989 - 52.6%. The lowest percentage of hard grain was recorded in 1986 -14.7% and the highest in 1989 -28.75%. In other years, the parcentages were: 1987 - 25.7%, 1988 - 26.5% and 1990 - 27.75%. The highest total germinability was obtained in 1990 - 88.65%, while the lowest was in 1986 - 85.15%. Approximately the same germinability was obtained in 1987 - 85.45%, 1988 - 85,40% and 1989 - 86.95%. Based on these five-year results, conclusion can be made that the agroecological conditions in the Banat region are stable and, as such, make it possible to produce lucerne seed, variety OS-66, of high viability. The most favorable climatic conditions were those in 1990, when the highest total lucerne seed viability of 88.65% was obtained. The average germinability (1986/90) varied from 50.55% to 64.5%, hard grain 24.6% variation from 14.7 - 28.75% and total germinability 86.32% varied by years from 85.40% - 80.55%. A high percentage of hard grains is a varietal characteristic because synthetic lucerne varieties compared to pure varieties give a higher hard grain percentage. Judging by the five-year results, conclusion can be made that the agroecological conditions of this region are very good and that the total rainfall in June, July and August and its distribution by decades was the most favorable in 1986 and 1990, because the highest viability seed was obtained during these two years.

INFLUENCE OF VEGETATIVE AREA ON PEPPER (Capsicum annuum L)
SEED YIELD AND QUALITY
By
JANKULOVSKI D.
SUMMARY
The goal of this investigation was to determine the influence of the vegetative area on the yield and seed quality in Kurtovska kapija and Shorok shari varieties. Five variants of vegetative areas with different configuration have been examined: 1. 800 cm2; 2. 900 cm2; 3. 1000 cm2; 4. 1200 cm2 and 5. 1400 cm2 per plant. The experimental results show significantly higher seed yield in both varieties. In the first variant of Kurtovska kapija and Shorok shari the yield was higher by 22.4% and 17.9%, and in second variant by 18% and 17.8% respectively, in regard to the control variant (5) (Tab. l). The germination and absolute seed mass have not shown significant difference regarding the control (Tab.2).

REACTION OF SELFPOLLINATING LINES OF MAIZE HYBRIDS TO CHEMICAL PREPARATIONS FOR TREATMENT OF SEED
By
IVANOVIĆ D., STOJKOV S., KAITOVIĆ Z., BAČA F.
SUMMARY
The response of five inbred lines and three maize hybrids to fungicides (Kaptan SP-4, Vincit F. Vitavax 200 FF) and their combinations with insecticides (Promet 400CS and Force 20CS) were observed in this study. The investigations were conducted under laboratory and field conditions. According to obtained results, it is not possible surely to determine which preparation or combination had the most effective protection. This is due to different genotype responses to the same chemical. Four (ZP16-G1, ZP15-G2, ZP80-G3, ZP106-G5) out of five investigated inbreds had a positive response to seed treatment with a combination of fungicide Kaplan SP-4 and insecticide Promet 400CS. The similar response was denoted in plants of hybrids progenies.

EFFEST OF CULTIVAR AND CROP DENSITY ON GRAIN YIELD AND REALIZED NUMBER OF PLANTS OF SPRING FORAGE PEA (Pisum Sativum L.)
By
ĆUPINA B., ERIĆ P., MIHAILOVIĆ V.
SUMMARY
Three varieties of spring forage pea (Pisum sativum L.) were studied in field conditions for two years (1991 and 1992): NS-Lim, NS-Junior and Poneka. Row-to-row distances were 15, 25 and 35 cm (plant-to-plant was 35 cm) i. e. 130, 80 and 57 plants per m . In the both years, the studied varieties had high seed yield. The variety NS-Junior gave the highest yield with stand density of 15 x 5 cm, while NS-Lim and Poneka also gave high stand density of 25 x 5 cm. Graon yield significantly depends on realized number of plants per unit of area.

EFFECTS OF NITROGEN FERTILIZATION ON GRAIN YIELD OF ONION
By
ILIN Z.
SUMMARY
Relatively low yields of onion seed (from 300 to 600 kg ha-1) are achieved in commercial production. Consequently, it is significant, regarding the requirement for this seed in our country, to improve this production and provide sufficient quantities of the seed. Increasing doses of nitrogen fertilizer positively affects the increases of the pure grain yield. Application of N80P80K80 increases the yield of pure seed by 163,8 kg (13%) with respect to the control (1088,5 kg ha-1). Application of N80P80K80 results in grain yield of 1316,1 kg ha-1, which is by 227,6 kg or 17% higher yield than the control. High positive correlation exists between the increasing doses of nitrogen and the yield of onion seed r = 0,928**, and thus each 100 kg of N ha-1 increases grain yield by 149,3 kg ha-1 (b = 1,493).

THE INFLUENCE OF VARIOUS FUNGICIDES FOR SEED DESINFECTION
ON SEED GERMINATION AND THE MOST IMPORTANT MORPHOLOGICAL CHARACTERISTICS OF WHEAT PLANTS
By
ĐORĐEVIĆ D., MILIJIĆ MIROSLAVA
SUMMARY
The seed treatment for disease control and therefore the right choice of fungicides as well as the dose and quality of treatment represent extraordinary importance and one of the basic factors for high and stable agricultural production. That is why investigated a certain number of fungicides were investigated in the period from 1992-1993. On the basis of obtained results some suggestions on their further application are given.
Under the controlled laboratory conditions, the influence of fungicides for seed treatments on seed germination energy, seed germination, some morphological characteristics and disease control were studied. Several fungicides were tested in the experiment: Flutriafol + Tiabendazol + Etirimol (30 + 10 + 400 g/1 a.s.), Karboxyn + Tiram (200 + 200 g/1 a.s.), mankozeb (600 g/1 a.s.), Propiconazol + Imazalil + Tiabendazol (12,5 + 10 + 25 g/1 a.s.), Gutazine (350 g/1 a.s.), Basiccoppercarbonat (250 g/1 a.s.), Coppersulphat (250 g/1 a.s.), Copperoxychloridd (500 g/I a.s.), Propineb (700 g/1 a.s.), Cineb (650 g/1 a.s.), Ciam (750 g/1 a.s.). The experiments were performed on seed cv. Kraljevica, developed at Center for Agricultural and Technological Research - Zaječar. The obtained results showed the significant differences between fungicides for seed treatments on the investigated characteristics.

THE LIST OF INDENIFIED FUNGI ON GRAIN AND SEED OF MAIZE IN YUGOSLAVIA
By
PENČIĆ VIKTORIJA, LEVIĆ JELENA
SUMMARY
Almost a 100 fungi species have been discovered on grain and seed of maize up to now in Yugoslavia (Tables 1). The most numerous species are Fusarium (22), then Penicillium (16) and Aspergillus (12). Most damages were caused by Fusarium, then Nigrospora oryzae and Bipolaris zeicola. Sphacelotheca reiliana, previously dangerous seed pathogen, today is rarely noticed due to appropriately performed approbations.

METHODS FOR TESTING CORN SEED VIABILITY
By
MILOŠEVIĆ MIRJANA, RAJNPREHT JARMILA, ĆIROVIĆ M., ZLOKOLICA MARIJA
SUMMARY
The viability of four corn seed hybrids (NSSC-370, NSSC-444, NSSC-606, NSSC-607) was tested by different vigor tests (cold test, hiltner test, accelerated aging test, ingtensity growth test and complex stress vigor test) compared with laboratory and field germination during 1988 and 1989. Low germination values for all tested hybrids were obtained by applied vigor tests. The highest correlation coefficient was found between field emergence an cold test (0,95; 0,94) and accelerating aging test (0,90; 0,89). The smallest correlation coefficient was found between field emergence and hiltner test (0,62; 0,64).

STUDIES OF PATHOGENICITY OF ISOLATES ON GERMINATION PLANTS OF MAIZE UNDER LABORATORY CONDITIONS
By
STOJKOV SLAVICA, PENČIĆ VIKTORIJA
SUMMARY
Pathogenicity of five Microdochium bolleyi isolates on maize inbred lines (ZP15, ZP16, ZP80) were studied. The experiment was set up according to the method established by Molot et Sitnone (1967) on sterile sand and non-sterile soil. Pathogenicity of isolates, seedling growth and disease index were evaluated at the 3-leaf stage. M. bolleyi caused typical symptoms of necrosis and decay of tissue on studied plants. Disease index was higher in all inbred lines on non-sterile soil, while decrease in seedling growth was more significant on sterile sand. The inbred line ZP108 showed the highest susceptibility, while the isolate 90:MbZP2 expressed the highest pathogencity in both cases.
