DIRECTION OF CHANGES IN PLANT BREEDING TODAY
By
BOROJEVIĆ S., IVANOVIĆ M, ŠKORIĆ D., DOKIĆ P., ĐORĐEVIĆ S.
SUMMARY
Since intensive plant production has become too expensive - high prices and deficiency of mineral fertilizers, high costs of herbicides and pesticides and particularly of agricultural machinery, - it is necessary to develop sustainable agriculture, but with economic high yields.
Such a situation requires breeding of cultivars, which will be more economic in use of fertilizers and water, more resistant to prevalent plant diseases and insects, i.e. the breeding of low input cultivars.
It is also necessary to take into account the global climatic changes, which we are already facing, such as - pollution of air, soil and water, what has brought the rise of temperature, frequent droughts, etc. - in order to counteract negative changes, as well to make positive use of some factors.
Therefore, the main characteristics of low input cultivars should be: more modest plant type with smaller leaf area (in species where green parts do not represent the main yield), higher productivity and efficiency of photosynthesis, better absorption power of root system, increase of sink capacity, etc.
In this paper, the most important parameters and methods are outlined for wheat, corn, sunflower, sugar beet and some other field crops, to which the present and particularly the future breeding programs should be oriented.

ESTIMATES OF WHEAT HYBRID POPULATIONS IN F2 AND F3
GENERATIONS OBTAINTED BY BULK METHOD
By
JOVANOVIĆ B., PRODANOVIĆ S., MLADENOV N.
SUMMARY
Ten wheat populations in initial generations of mass selection were estimated by calculating mean values of recombinant genotypes developed as a result of dominant genes effects (Rd). Value of such recombinations:
Rd = (HP - fMp MP) / fRd
are used as a basic criterium in order to determine the importance of hybrid populations in selection. Based on the results, new superior wheat lines in Fe generations could be expected, from wheat hybrid populations (HP) Beogradanka x Skopjanka, Beogradanka x Zitarka, Skopjanka x Agrounija and Žitarka x Zemunka.

POP CORN HYBRIDS - DEVELOPMENT AND UTILISATION
By
PAJIĆ ZORICA, BABIĆ M.
SUMMARY
Pop corn is a special type of flints differentiating from the ordinary maize by formation of large "pop corns" after kernel explosion as a response to heating.
Pop corn hybrids have higher yield and high popping volume, so their production is economically justified.
In order to achieve the maximum popping potential it is necessary to perform harvest when the grain moisture is bellow 20%, to keep undamaged kernel pericarp and to enable grain moisture of 13-14% during popping.

THE SELECTION PROGRESS IN LOCAL SYNTHETIC POPULATIONS OF
MAIZE (Zea mays L.)
TRIFUNOVIĆ V. B., TRIFUNOVIĆ V., ROSIĆ K., IVANOVIĆ M.
SUMMARY
The purpose of this study was to determine selection progress for yield and other agronomic traits as well as to provide divergence in breeding material of maize synthesized from inbreds of a) local origin and b) local origin x exotic germplasm. Significant yield increase as a result of accumulation of favourable allels was determined in local synthetic populations and their test crosses. Incorporation of exotic germplasm significantly positively affected the level of these changes, especially for moisture content and stability of maize plant. A high combining ability in both synthesized germplasm with world-renowned testers (Lancaster and SSS) points to the fact that this breeding material has kept its divergence. Obtained results point out that new maize germplasm resources are convenient for improved hybrid combinations development by the choice of the appropriate selection procedure.

HOP (Humulus lupulus L.) BREEDING METHODS
by
GALOVIĆ VLADISLAVA
SUMMARY
The most important hop (Humulus lupulus L.) breeding methods were described in this paper. Traditional varieties have been bred by mass selection. Further improvement has been achieved by using individual selection. The most important crossing methods include single cross, three way cross, successive crosses, backcross and inbreeding. Backcross, similar to crosses between relatives, resulted in inbreeding depression. In contrary, success has been achieved by open pollination. Contemporary hop breeding is marked by application of poliploidy and biotechnological methods.

THE COMBINING ABILITIES FOR YIELD OF FIVE LOCAL AND THREE SYNTHETIC VARIETIES OF MAIZE
By
VANCETOVIĆ JELENA, DRINIĆ G.
SUMMARY
The combining abilities for yield of five local and three synthetic varieties of maize were investigated, using the method of diallel crossing without reciprocals. Yield trials were conducted in four locations, according to the complete randomized block design with four replications. The Method of 4 of Griffing (1956), Mixed Model B was applied for the analysis.
The results showed that additive genetic effect were of the primary importance for yield of these populations. Synthetic varieties had better GCA than domestic populations. No heterotic pattern was observed among domestic varieties.
Two opposite composites can be made from investigated populations. The best method of improvement with these composites would be: first mass selection, than 1 or 2 cycles of S1 family selection and finally reciprocal recurrent selection for yield.

GENETIC VARIABILITY ON THE YIELD OF GRAIN IN TOPCROSS
POPULATION OF MAIZE (Zea mays L.)
By
DRINIĆ G., VANČETOVIĆ JELENA
SUMMARY
The possibility of improvement of grain yield in a commercial maize hybrid by use of two genetically non related populations was observed. Two inbred lines (L82 and L15), components of a hybrid combination and synthetic populations (ZPEP and BS12C8C1) were used. The trials with studied top-cross progenies were set up according to Nested design in three locations.
The inbred L82 achieved higher average grain yield in a combination with BS12C8C1, while the inbred L15 achieved it with ZPEP. Genetic variances for all examined combinations were significant. On the base of obtained parameters, the populations ZPEP and BSlZC8C1 should be used as a source for improvement in the inbreds L82 and L15, respectively.

S2 TEST CROSS RECURRENT SELECTION OF SELF FERTILE SUGAR BEET GENOTYPES APPLYING RECESSIVE GENES OF NUCLEAR MALE STERILITY
By
KOVAČEV L., MEZEI SNEŽANA, ČAČIĆ N., SKLENAR P.
SUMMARY
Improvement of genetic potential for the most important quantitative characters of sugar beet is conditioned by the production of new genetic variability. It is simple to produce new genetic variability as well as to fix superior genotypes with the selection material possessing the gene of self fertility SfSf (dominant) combined with the gene of nuclear male sterility aa (recessive).
The results of our study indicate that 82 test cross recurrent selection increased successively the frequency of desirable genes for yield of sugar beet root and sugar although the selection was performed for sugar yield. The frequency of desired genes for sugar content was lower than for root and sugar yield.

COMBINING ABILITY FOR THE NUMBER OF PODS PER SOYBEAN NODY
JOCKOVIĆ D., HRUSTIĆ MILICA, BEKAVAC G., POPOV R., PURAR BOŽANA1
SUMMARY
Seven soybean genotypes were diallely crossed to study the combining ability and the gene effects for the number of pods per the next soybean genotypes: Krajina, Bačka, Kolubara, 315110, Drina, Sturdy, 32079. Analysis of variance of combining ability was performed according to Gtriffing (1956) method 2, model 1.
Significant differences between parents and their fi hybrids were obtained for the number of pods per nody (Tab. 1). The average number of pods per soybean nody was between 3,8 (line 32079) and 6,2 (variety Kolubara, Tab. 1). The average number of pods per nody in the fi generation ranged from 4,3 (315110 x 32079) to 7,1 (Kolubara x Drina).
Analysis of variance for combining ability showed that general combining ability was significant indicating the importance of additive gene effects in the inheritance of the summer of pods per nody. The best general combiners for the number of pods per nody was variety Kolubara.

SYNTHETIC POPULATIONS WITH HIGH OIL CONTENT AS SOURCES FOR EXTRACTING PARENTAL LINES FOR HIGH OIL HYBRIDS
by
SARATLIĆ G., ROŠULJ M.
SUMMARY
Phenotype (mass) recurrent selection for increase percent of oil was conducted on two maize (Zea mays L.) populations. Greater direct response to selection was detected in the DS7u population per se than in the YuSSSu population per se (15,13 vs. 12,80% cycle"1). The indirect response obtained in the interpopulation crosses was 14,35% cycle"1. An increase percent of oil was followed by grain yield reduction in the DS7u population and interpopulation crosses, while yield remained unchanged in the YuSSSu population. Inbreeding depression increased in the DS7u population and interpopulation crosses, but showed an inconsistent trend in the YuSSSu population.

CROPS IN NOVI SAD
By
VASIĆ MIRJANA, GVOZDANOVIĆ-VARGA JELICA, J. ČERVENSKI
SUMMARY
The scientist in the Institute of the Field and Vegetable Crops have been working on the breeding of coloured and white beans of determinative growth. The lines of coloured beans NSP-1 with gold-yellow grain and L-74 the greenish type are created. They are both early types, higher and have greater yield than Rozalia variety, and they are at the level of Slavonski zeleni. Among the lines with white grain the most interesting six ones belong to different varieties by the shape of the grain. The standard used in this trial was Galeb variety . The plants of newly developed lines are higher than the standard, and the first pods are formed at higher height. The duration of vegetation is almost equal to that of Galeb variety. Most of the lines have higher yield or at the level of Galeb variety as presented in the results of a few year investigation period.

NEW CLONES OF SPRING GARLIC
By
GVOZDANOVIĆ-VARGA JELICA, TAKAČ A., VASIĆ MIRJANA
SUMMARY
In our region, garlic growing has a long tradition. Domestic varieties and populations are most often used for the production. The paper presents three-year results of the comparative analysis of seven clones, obtained from clone selection from domestic populations, and the variety Piros. The elements studied are: morphologic characters of bulbs (Tables 1 and 2, Figure 1); bulb mass, number of cloves, mass of clove, dry matter percentage and yield of spring garlic (Table 2). All studied clones had significantly higher mass of buylbs, and more and larger cloves than the variety Piros. The average yield for three years of all clones was by 21.55% higher than the standard.

ANALYSIS OF GRAIN YIELD COMPONENTS IN RANDOM POLLINATION OF
ALFALFA SYNTHETICS
By
ĐUKIĆ D.
SUMMARY
Fight alfalfa synthetics were analyzed for the components of grain yield in polycross. Average inflorescence length was 2.63 cm and there were 26.6 flowers per inflorescence. Except in synthetic of Fl generation on cms basis, pollen fertility was night (71.8 %). The number of ovules per ovary was 9.7. The number of ripe pods per inflorescence was 8.2, with 2.92 seeds per pod and 1.98 g per 1000 seeds. Broad row alfalfa gave grain yield which ranged from 27.2 to 42.7 gm-2 in 1991/93. According to stem height and grain yield stability, the synthetic 7 Syn 1, a new prospective variety with high genetic potential for fodder and grain yield, gave the best results.

EFFECT OF SELF-POLLINATIONON POLLEN FERTILITY OF ALFALFA
By
KATIĆ S., LUKIĆ D.
SUMMARY
The S0, S1 and S2 generations of 11 alfalfa varieties were studied for pollen fertility. Self-pollination decreases pollen fertility and the number of fertile pollen grains. All studied varieties and all self-pollinated generations did not show decreased pollen fertility. Statistically significant correlation exists between pollen fertility and the number of fertile pollen grains, and both parameters can be used for the evaluation of pollen fertility.

NEW GENETIC APPROACH TO MULTIPLE RESISTANCE TO RUST DISEASESF IN WHEAT
By
BOROJEVIĆ KATARINA, WORLAND A.J., LAW C.N.
SYMMARY
Resistance of adult plants to rust diseases in wheat is controlled by a complex balance of genes promoting resistance and susceptibility. They are located at different chromosomes of wheat varieties, but most often in cited literature at 7D. The level of resistance is determining by balance of opposing set of genes, that either promote resistance or promote susceptibility. In this paper results of such research are described and possibility of applying them to breeding of wheat is discussed.

RESULTS IN WHEAT SELECTION ON RESISTANCE TO POWDERY MILDEW
by
STOJANOVIĆ S., STOJANOVIĆ JOVANKA
SUMMARY
Resistance of 969 new Yugoslav wheat lines to powdery mildew fungus was investigated in the period 1988-1992. The investigation showed that many lines, distinguishing in other positive agronomic characteristics, possess high resistance to powdery mildew. The total number of immune lines was 232 (Table 1). In the first year number of immune lines was 15 (7,62%) and in last one 47 (32,42%). This shows tendency of increasing resistance over years. Some of these wheat lines would be grown as varieties in future.

PEPPER DISEASES AND POSIBILITY FOR THEIR PREVENTION BY GROWING RESISTANT VARIETIES
By
STEVANOVIĆ D., MIJATOVIĆ MIRJANA, OBRADOVIĆ A., ZDRAVKOVIĆ M.
SUMMARY
A progressive decrease of yields in pepper production has been registered during previous years. Beside unfavorable ecological conditions (drought, high temperature, low relative humidity, etc.), virus diseases are the main reason for this yield reduction. In order to prevent appearance of these diseases a new breeding program was established in the Center for Vegetables from Smed. Palanka. This program is based on pepper selection on resistance to Tobacco mosaic virus (TMV) and Cucumber mosaic virus (CMV) by using, for the first time, some wild species as a gene resistance donors. As a result of 15 years long investigations we came up with pepper lines which possess a high level of resistance to TMV and CMV.

DETERMINATION OF SPRING WHEAT GENOTYPES SUITABLE FOR GROWING IN HILLY AND MOUNTAINOUS AREA
By
PRŽULJ N., BOGDANOVIĆ M, NINKOVIĆ V.
SUMMARY
There are considerable surfaces of agricultural land in hilly-mountainous region, where spring wheat can be more successfully cultivated than winter wheat. Spring wheat sowing on time and high yield realization is not possible every year because of unfavorable weather conditions during spring time and badly prepared soil. So, the more adaptable genotypes to the later sowing have to be chosen from the available germplasm. The evaluation of 29 lines of spring wheat originally from Mexico has been investigated for three years to determine their behavior under conditions in Sokolac place. At the later sowing time Mexican lines gave greater, and at the earlier sowing time lower yield than the check, variety Jarka. Resistance to a rust disease was satisfying, but to the Helminthosporium sp., Erysiphe graminis and Septoria tritici not. Some of genotypes can be used as donors of dominant Vrn genes and neutral photoperiod reaction, as well as of genes for tolerance toward stem and leaf rust in the spring wheat breeding program.
