SPIKE CHARACTERISTICS - SELECTION CRITERION FOR YIELD IN WHEAT
by
KOBILJSKI, B. i DENČIĆ, S.
SUMMARY
The effect of yield components (spike number/m2, kernel number/spike and kernels weight/spike), spike length and spike index on grain yield on 100 high-yielding arid 100 low-yielding wheat genotypes were analysed. The high-yielding genotypes were analysed. The high-yielding genotypes achieved significantly more spikes/m2 and higher spike index, but significantly less kernels/spike and shorter spikes compared with the low-yielding cultivars. No significant differences occurred in the analysed groups for kernels weight/spike. In the high-yielding group, no significant correlations were found between grain yield and spike number/m2 as well as grain yield and spike index in the low-yielding group. For both analysed groups, highly significant negative correlations were detected between kernel number/spike, kernels weight/spike and spike length on one side and spike number/m2 on the other. Furthermore, in the high-yielding group, highly significant positive correlations were determined between kernels weight/spike on one side and kernel number/spike and with spike index on the other. Increases in kernel number/spike, kernels weight/spike and spike length in wheat, do not necessarily result in yield increase, while increase in spike number/m2 and spike index are good indicators of high-yielding ability.
Key words: wheat, yield, yield components, ear length, ear index, correlations

PHENOTYPIC SIMILARITY OF WHEAT WITH ITS RELATIVES AND VARIABILITY OF
YIELD COMPONENTS
By
PANKOVIĆ, L., PETROVIĆ SOFIJA, DIMITRIJEVIĆ, M. and KRALJEVIĆ-BALALIĆ MARIJA
SUMMARY
Number of wheat and related wild species that were collected in former Yugoslavia were studied at the Institute of Field and Vegetable Crops in Novi Sad, and at Kyoto University in Japan. Our investigations included four species of genus Triticum (Tr. aestivum ssp. vulgare, Tr. durum. Tr. turgidum and Tr. monococcum) and four species Aegilops (Ae. comosa, Ae. biuncialis, Ae. triuncialis and Ae. ovata). Following parameters were measured and analysed: spike lenght, number of grains per spike and weight of 1000 grains. Measured yield parameters were analysis (PCA) and cluster analysis, and phenotypic distances between wheat and related wild species were calculated. Highly significant differences between wild wheat species were found in all three examined parameters. Between Triticum species highly significant differences were detected only in the weight of 1000 grains. According to the PCA analysis wheat species Tr. vulgare and Tr. monococcum are similar to the related species Aegilops comosa. According to the cluster analysis of three examined parameters Ae. ovata can be classified as a separate group of relatives. Our results provide the classification of wheat and related species which in useful for the introduction of desirable traits in to Triticum aestivum ssp. vulgare.

IVANOSKI, M., NIKOLOVSKI, M.
SUMMARY
From the comparison investigation for harvest index of some winter wheat cultivars (Babuna, Radika, Lihnida, Nova Skopjanka, Lizinka-1, Miljenka, Lizinka-2, Skopjanka, Jugoslavija and Partizanka) planted in two regions: Skopje and Ovče Pole it can be concluded: The harvest index, in grain measure is dependent from the agroecological condition in the year. The agroecological conditions in the region of Skopje was better for produce more biological yield for 22,8%, more grain yield for 27,5% and more harvest index for 8,6% than the agroecological conditions of region of Ovče Pole. For the investigation cultivars it was not found the genetic differences for biological yield, but for the grain yield and harvest index the differences has been confirmed.
Significant more grain yield it have the next cultivars: Radika and Miljenka in the region of Skopje, and cultivars, Miljenka and Lizinka-2 for the region of Ovče Pole, compared to the control cv. Partizanka. Only cultivars Radika and Miljenka had significant more harvest index in the Skopje and cultivars Babuna, Radika and Lihnida in Ovče Pole.

TOLERANCE OF NOVI SAD WINTER WHEAT GENOTYPES TO PUCCINIA RECONDITA TRITICI
by
JERKOVIĆ, Z.
SUMMARY
Tolerance of ten winter wheat genotypes to Puccinia recondita tritici was investigated in 1995-1997 using an original method. The protection of plots artificially infected with leaf rust pathogen was against Erysiphe graminis tritici. Control plots were protected from Puccinia recondita tritici too. Yields were compared.
Results obtained from our two-year study of narrow and broad sense tolerance showed that such a relative characteristic, just as any other relationship with pathogens, could be decreased or increased every year as a result of the dependence on environmental conditions. Eight studied varieties expressed a higher level of tolerance in comparison with NS 40/39 in two years. The most tolerant line was NS 81/90. In 1996 and 1997, when high intensity attacks occurred later, the tolerant lines were Kosuta and Slavija. Relatively small losses were recorded in NS 48/91 and Evropa 90. Balkan proved to be a variety with a low level of tolerance in the broad sense. In the variety Pobeda even late attacks of medium intensities caused significant damage in comparison with other genotypes.
Key words: leaf rust, winter wheat, tolerance

STATUS, PROBLEMS AND PERSPECTIVES OF OAT SEED PRODUCTION IN
SR JUGOSLAVIA
by
MIHAJLIJA, G., MAKSIMOVIĆ, D., JEVTIĆ, S., PAVLOVIĆ M. and DUŠANKA MIHAJLIJA
SUMMARY
Seed technology is a basis for the production of high quality of seeds. The main factors for obtaining high grain yields are variety and the seed. Recently, in our production are using undeclared seeds for the seeding, especially in private estate.
The production and areas of oats during the period from 1955 to 1994 are decreasing and averaged yields are increasing. As result this is an introduction of next high-yielding varieties in the production and application of new practice management in their growing.
In last time, there is a great interest for naked forms of oats. Up to date, Institute "Serbia" Center for small grains "Kragujevac" has five registered owned oats varieties: Rajac, Slavuj, Mediteran, Lovcen and Labud. In our institute, it is intensively working on breeding of naked forms of oats.

POSSIBILITIES OF HYBRID MAIZE SEED PRODUCTION IN FR YUGOSLAVIA
by
GRADINSKI, G., VIDOJKOVIĆ, Z., PAVLOV, M., SELAKOVIĆ, D., MIŠOVIĆ M.M.
SUMMARY
The hybrid maize seed production is an activity present in any country where maize is grown on large areas. However, there are certain specificities related to maize growing practices, such as crossing of parental components, drying, processing and preparation of seed for marketing, which can be a limiting factor for the final success. Therefore, small countries are forced to purchase hybrid maize seed from the countries which can organize such production.
As maize was and is one of the most important crops in Yugoslavia, paying great attention to the maize seed production is an absolutely reasonable activity. The annual production of hybrid maize seed in previous Yugoslavia was estimated to 60,000-90,000 tons.
The trend of the maize seed production development is continued in today Yugoslavia, as all facilities for seed processing are mostly maintained and majority of seed producers are located in FR Yugoslavia. Although, the territory of FR Yugoslavia decreased, maize crop is grown on approximately 1.5 M ha. The hybrid maize seed production is averagely organized on 10-12,000 ha with the total production of 20-30,000 tons of seeds. This indicates that we are still able to produce sufficient amount of seeds not only for our own needs, but also for export.
In order to utilize all possibilities that FR Yugoslavia have for maize hybrid production it is necessary to work more actively on selection and development of new hybrids of FAO 400-500, improve seed production technology, to grade the entire amount of produced seeds and to pack them according to the number of seed per planting unit, to determine an adequate parity between commercial and seed maize, to introduce a proper advertisement which will provide expanded seed marketing both in our and other countries, to aim seed marketing to already known as well as to new markets capable for payment. All these should contribute to a greater and more profitable production of hybrid maize seed, so important and prospective activity for Yugoslavia.

MORPHOLOGICAL AND GENETIC ANALYSIS OF CORN INBRED LINES
by
ZLOKOLICA, M., JOCKO VIĆ, D., SIMIĆ D., MILOŠEVIĆ, M, NIKOLIĆ, Z., POPOV, R.
SUMMARY
On the basis morphological and genetic analysis of grain and seeding the combination traits of selfpollinated group of corn lines were investigated. The certain morphological analyses of individual grains were determined for each line. Genetic traits of lines were studied on the basis of isozymes as genetic markers. The lines were analysed in the stage of seedlings on the basis of the following enzyme polymorphism: ACP, MDH, GLU, PHI, PGD, PGM, IDH, CAT, ADH, EST, AMP and GOT. Electrophoretic analysis was used for monitoring the expression of allelic variants of 18 identified loci, from which 10 were polymorphic, and eight were monomorphic. Allelic variants for polymorphic loci were of limited numbers. Because of that there were small genetic differences between certain pairs or group of lines. Some groups were genetically identical on the basis of all analysed loci. Lines Mo 17 and 659A were mutually the most divergent pair, and according to certain allelic variants and in relation to other lines. Unique allelic variants of several loci were found for Mo17 line. In some lines heterozygosity of certain loci was found which pointed out the genetic specifity and diversities of the given genotype in relation to other breeding material.

EFFECTS OF PLANTING DENSITY AND MINERAL FERTILISERS RATES ON YIELD AND KERNEL NUMBER IN SEED MAIZE
by
JOVIN, P., VESKOVIĆ M.
SUMMARY
The trials were carried out on the experimental field of the Maize Research Institute, Zemun Polje, in Krnjesevci during 1994 and 1995. The following parameters were observed:
1. planting density: 1-57,100 plants ha-1,11-71,400 plants ha-1, and 85,700 plants ha-1, 2. mineral fertilizers rates: I rate: 90 kg N ha-1, 72 kg P2O5 ha-1, 48 kg K2O ha-1, II rate: 120 kg N ha-1, 94 kg P2O5 ha-1, 62 kg K2O ha-1, III rate: 150 kg N ha-1, 120 kg P2O5 ha-1, 80 kg K2O ha-1.
Planting density did not significantly affected yield (1-4.56 t∙ha-1, II - 4.61 t∙ha-1, III-4.70 ha-1), while the highest yield (4.68 t∙ha-1), in relation to a fertilizer rate, was obtained with the medium rate (120 kg N ha-1, 94 kg P2O5 ha-1).
The highest 1000-kernel weight was achieved with the lowest density and the greatest fertilizers rate (225.3, 223.5 g).
The largest number of germinated seeds (23,843,000 ha-1) was obtained in the highest density while in respect to fertilizers the greatest number (23,794,000 ha-1) was achieved with the medium rate.
The fraction participation in seed mass was uniform over all three densities, while it varied over fertilizers rates.
Key words: crop density, mineral fertilizer, yield, mass of 1000 seeds, number of seeds per hectare, seed fraction

EFFECT OF HARVESTING DATE ON SOME QUALITATIVE TRAITS OF MAIZE SEED
By
BIBERDŽIĆ, M., LAZOVIĆ D.
SUMMARY
The investigations were conducted in the region of Kosovo. In this paper the effect of harvesting date on some of the maize seed traits was studied. The obtained results have shown that the seed qualities (germination energy and germination) are achieved very early - immediately after seed setting. Absolute mass is slowly increased reaching the highest value on 67th day from pollination. The high seed moisture level prevents maize seed to be harvested earlier.
Key words: maize, absolute mass, germination energy, germination, harvesting date

COMBINING ABILITY AND MODE OF INHERITANCE OF ACHENE DIMENSIONS IN F1
GENERATION OF CONFENCIONARY SUNFLOWER
(Hellianthus animus var. macrocarpus DC. (Ckll.))
by
DOZET, B., JOVANOVIĆ, D.
SUMMARY
The manuscript examined general (GCA) and specific combining ability (SCA) of selected confectionery inbred lines for length, width and thickness by line x tester analyses. The best GCA was observed in line CMS L-268 for seed length, in line CMS L-167 for width and in line CMS L-368 for thickness. From the restorer lines the best GCA was observed in Rf Rumenčanin for seed length and width and in Rf Ličanin for thickness. The best SCA was established in CMS L-286 x Rf Rumenčanin combination for seed length and in CMS L-268 x Rf Ličanin for seed width and thickness. The seed length and wide were intermediary in F1 generation in all hybrid combinations and in a three hybrid combinations expressed dominance and partial dominance by better parent for seed thickness.

INTERDEPENDANCE OF GRAIN YIELD AND CHEMICAL COMPOSITION OF SOYBEAN GRAIN IN IRRIGATION AND NON-IRRIGATED CONDITIONS
by
MILADINOVIĆ, J., HRUSTIĆ, MILICA and TATIĆ, M.
SUMMARY
During 1994 and 1995, 21 soybean varieties and lines have been tested in order to investigate the influence of irrigation on grain yield and chemical composition of soybean grain. In both years of investigation grain yield and protein content were higher in irrigation variant, while oil content was lower. However, both protein and oil total yield per hectare were higher in irrigation variant. Coefficients of genotypic correlation between investigated traits in irrigation were similar to those in non-irrigated variant. Coefficients of phenotypic correlation were different than those in non-irrigated variant, which points on strong influence on environmental factors on interdependence of investigated traits.
Key words: soybean, yield, protein, oil

THE INFLUENCE OF Pb-ACETATE ON THE SEED GERMINATION OF SOME VEGETABLE FARMING TYPES UNDER CONDITIONS OF EXPERIMENTAL INTOXICATION
by
ILIĆ, Z., MILANOVIĆ LIDIJA
SUMMARY
On the basis of our investigation we came to the following conclusions:
Sensitivity of the seed of certain vegetable farming types on higher concentrations of Pb-acetate is different which points to different genetic particularities of each plant specifically. Depending on concentrations of germination in different degrees, due to the plant type. High concentrations of Pb-acetate (10-2 M) in lettuce seed totally prevents germination while in seeds of the other types germinations decreased 26% in carrots, 17.1% in brussels sprouts while in radishes only 7,3% in relation to the control. Double higher concentration of Pb-acetate (2 x 10-2 M) causes considerably higher loss of germination almost in all the vegetable farming types while in some e. g. carrot and lettuce it is totally eliminated. The highest tolerance in regard to the increased concentrations of Pb-acetate is found in a seed of onion.
Acetic medium is a considerable precondition for a sooner penetration of Pb into the seed which inhibits germination. In order to reduce negative influence of Pb the use of different helator of heavy metals such as: Na and Cl salts acetic acid - EDTA is applied. EDTA is a helator which reduces toxicity of Pb as it combines with it and disables its inhibitory influence on the ermines responsible for the germination.
In a medium of high
concentration of Pb-acetate (2 x 10-2 M) + EDTA percentage of seed
germination is higher than in onion 17.6%, radishes 20.4%, brussels sprouts 42.6%
and peas for 77.9% in relation to the seed germination only in presence of
Pb-acetate. Other concentrations from 10-2 M to 10-5 M
Pb-acetate with presence of EDTA do not deviate much and are on the level of
seed germination in control variant (only EDTA). In carrot seed and brussels
sprouts, in concentration of Pb-acetate of
10-5 M and in the presence of EDTA decrease of seed germination in
relation to the control for 2.7% that is 2.3% in noticed.

EFFECT OF LENGHT OF STORAGE AND PROCESSING METHOD ON SEED QUALITY OF TOMATO (Lycopersicon lycopersicum Mill.)
by
TAKAČ, A., GVOZDENOVIĆ, D. and JOVIĆEVIĆ, D.
SUMMARY
This paper shows how the biological characteristics of tomato seeds change during seven years of storage. Standard and dehaired and non-dehaired first-reproduction seeds of the variety Novosadski jabuchar were studied. Each year seed vigor and total seed viability were monitored using the standard methodology. In dehaired seeds, a sharp fall in seed vigor was recorded after the fifth year of storage (26.5%), while in non-dehaired ones such a decrease occured after the sixth year (17.5%). After seven years of storage seed vigor in dehaired and non-dehaired seed decreased to 8.13 and 2.15%, respectively. Total seed viability decreased at a considerably lower rate: after seven years it fell to 73.0 in dehaired and 83.25% in non-dehaired seeds.
Key words: tomato, seed, germination

INFLUENCE OF SAWING TIME AND VEGETATION AREA ON POSSIBILITY OF PRODUCTION OF CARROT SEED THROUGH THE SYSTEM "SEED - SEED"
By
ILIĆ, Z.
SUMMARY
On the basis of our investigation in regard to the choice of sawing time and vegetation area on possibility of production of carrot seed through the system "seed - seed" in agroecological conditions in Kosovo and Metohija it can be said as follows:
The biggest crops is achieved in the first sawing period (from 28th VII) in the highest seeding area of 22,7 g per plant, with 12 primary and 35 secondary and tertiary flowers. In the smallest seeding space in the third feeding period (from 18. VIII) we have crops of only 7,3 g per plant and that of one primary (2.6) and 5 secondary (4,7) flowers.
Small vegetation area of 25 x 10 cm and big plants (286 000) prevent growth of a number of branches, secondary and tertiary, so that the biggest amount of seed is obtained from primary flowers which ripen simultaneously. The biggest crops is obtained in the first period of sawing time in the smallest vegetation area 25 x 10 cm (2948 kg/ha) and the least in the third cropping period with the largest vegetation area.
In addition to the height crop quality of carrot seed is also high (germination is above 90%).

THE INFLUENCE OF MATURITY STAGE AND PLACE OF FRUIT FORMATION ON A PLANT SOME OF THE QUALITATIVE DISTINCTIVE FEATURES OF PAPPER SEED
by
BIBERDŽIĆ M., ILIĆ, Z., MILENKOVIĆ LIDIJA
SUMMARY
When the Gold medal sort is concerned, seed obtained from fruits formed at all stages can be used for further reproduction, because germination goes from 67 percent at the fourth to 96 percent at the first stage. The greatest seed quantity is got from fruits at the third and fourth stage (1.17 and 0.95 g), and there are also significant different between seed quantities produced at the first and third stage. Fruit yield whose pericarp can be used for different kinds of treatment after taking out the seed is 69 t/ha.
The Soroksari sort, as a late-ripping one, gives fairly weak and uneven seed yield under the same conditions. Seed from fruits at the first stage alone has good qualities (93 percent germination), while it is quite different at other stages. The queatest seed yield per fruit is at the second stage (0.94 g) and the least at the fourth one (0.32 g). The average seed yield per plant is approximately 8 g, that is 642 kg/ha. As for this sort, sowing, i.e. planting out is recommended to be done somewhat earlier and with a greater plant density.

INTERDEPENDENCE OF FACTORS AFFECTING THE DEVELOPMENT OF THE OYSTER MUSHROOM MYCELIUM (Pleurotus ostreatus)
by
BUGARSKI DUŠANKA, GVOZDENOVIĆ, B., VASIĆ MIRJANA I JOVIĆEVIĆ, D.
SUMMARY
Changes in major environmental conditions that occur during the development of the mycelium will produce variations in this development. The objective of our study was to investigate the joint effect of the temperature, concentration, and pH value of the nutrient medium on the initial and final growth of the oyster mushroom mycelium (strain NS 77). The trial was established in five climatic chambers, each with a different temperature. Three different concentrations of carbohydrates and five pH values of the medium were used to grow the mycelia and there were five replicates. The medium following combination of the three factors proved to be the best for initial growth: the highest concentration of carbohydrates, 35 °C, and pH 5.5. The medium with the highest concentration of carbohydrates was also shown to be the best for final growth, but the temperature had to be at 25 °C and the pH at 7.0 (after the first reading, growth at 35 °C ceased completely).
Key words: different temperatures, pH value, nutrient medium, grow

by
LUKIĆ, D., MILOŠEYIĆ, M., ZLOKOLICA, M., VASILJEYIĆ, S.
SUMMARY
Portion of blind seeds in alfalfa was studied in laboratory in 1996. Seeds were germinated in Petri dishes in a thermostat at a constant temperature of 20 °C for 10 days. The seeds which failed to germinate in 10 days were considered as blind seeds. The analysis included five lines of each M. sativa L. and M. media Pers. and five populations of M. falcata L. The average populations were 7.1%, 13.1% and 48.6%, respectively. Large seeds with the largest mass had the smallest portions of blind seeds (5.7, 12.9 and 25.9%, respectively), while small seeds had much larger portions (12.5, 18.5 and 47.1%, respectively). The pronouncedly kidney-shaped seeds and oval kidney-shaped seeds had 4.7, 11.2 and 26.7% of blind seeds, respectively. Angular seeds had larger portions of blind seeds (12.1 – 16.1%) and oval seeds the largest (45.5%).

CHANGES, ACHIVEMENTS AND DIRECTIONS IN TOBACCO BREEDING
by
DRAŽIĆ, S.
SUMMARY
Our results achieved in tobacco breeding so far (Nicotiana tabacum) are pretty modest. Assortment is mainly presented by the varieties obtained from populations created by hybridization and F1 hybrids (hybrid varieties). Besides that, some of authentic varieties are presented in production.
The future of tobacco as industrial plant will depend on several factors which determine the most important directions of breeding of this plant species.
Inside the genus of Nicotiana and species N. Tobacco there is a great variability concerning the most of the traits. By using appropriate breeding methods (classical methods and methods of genetic engineering) genotypes satisfying different demands can be created.

EFFECT OF SOIL FERTILITY ON SEED PRODUCTION POSSIBILITES
by
SEKULIĆ P., HADŽIĆ V., ĆIROVIĆ M.
SUMMARY
Hundred-twenty-seven soil profiled have been opened within the framework of realization of the Basic Program of Protection, Management and Use of Agricultural Land in Bački Petrovac Municipality. Three samples from each profile have been analyzed for soil fertility and contamination. The results obtained have shown that the soils in the Backi Petrovac municipality are in general highly fertile.
High soil fertility is a prerequisite of a successful seed production. We have established the following minimum requirements for seed production establishment: pH in KC1 - 6,0-7,5; Humus > 2%: AL-P2O5 - 10-50 mg/100 g; AL-K2O - 10-50 mg/100 g; Cu - 5-50 mg/kg; Mn – 10-100 mg/kg; Zn - 5-15 mg/kg; Co - 1-5 mg/kg; Mo - 0,15-0,5 mg/kg; Ni < 50 mg/kg; Cr < 100 mg/kg i Pb < 100 mg/kg.
The results have shown that only 19 out of the 127 profiles analyzed meet the established requirements. The acceptable profiles belong to the chernozem soil type, the most frequent type being chernozem on loess and loess-like sediments, calcareous, gleyed, medium deep.
Key words: fertility, seed production, soil type, chernozem
