PRODUCTION AND SEED CROPS CONTROL IN F.R. YUGOSLAVIA
by
DOKIĆ P., MIHALJEV I., ĆIROVIĆ M., DINOVIĆ A., PAVLOV M.
SUMMARY
Number of climate and soil investigations, as well as gained experiences has shown that there are favorable climatic and soil conditions (rainfall, temperature, soil, sunshine etc.) for production of almost all field and vegetable plant species in Yugoslavia.
Besides favorable natural conditions, scientific-expert and technical-technological potentials are at the level, which enable us to produce much more quality seed and planting material, not only for domestic use, but also for exporting to those countries not having such favorable conditions for seed production. In the last 50 years the value of exported seed and planting material accounted for 1.6 million dollars. During the time sanctions were imposed upon our country the value of exported seed accounted for 80 million dollars.
In this paper the area of average yield of seed per hectare and total quantity of processed seed of main field crops in Vojvodina and Yugoslavia such as: wheat, maize, sugar beet, sunflower and soybean seed, as well as the need for seed in SR Yugoslavia are shown. The special attention is given to the need for greater seed crops control with the aim of preserving genetic purity especially in production of hybrid seed F, generation.

STRATEGIC MARKETING IN AGRICULTURE AND SEED SERVICES
By
ILIĆ V. and MIRIĆ M.
SUMMARY
The study encompasses lack of the marketing approach in the past, its neglecting today and its exclusive necessity in the immediate future of the Yugoslav seed production and seed services. The radical changes of social and economic relations in the county and abroad, requiring market adjustments of seed companies, are especially emphasized, as well as defining of the managing the seed companies in order to undertake the urgent marketing activities.
Seed production has a pronounced strategic and developmental importance due to its nourishing and ecological dimensions. Through the seed, seed production results in the reproduction of a variety, a principal agro-innovation, on which field production, processing and national diet are based. Therefore, there is on prospects of seed production without the acceptance of a business philosophy founded on marketing. Administrative agencies and bodies of management are the leading agents of marketing transformations of seed companies.
Key words: agriculture, seed science, strategy of marketing, variety, seed

THE ROLE OF BIOTECHNOLOGY IN CROP BREEDING ON THE END OF XX CENTURY
by
G. DRINIĆ, SNEŽANA MLADENOVIĆ DRINIĆ
SUMMARY
Global food demand is forecast to at least double and possible triple, by the year 2050 when the world population is expected to reach 11 billion people. In order to ensure increased nutrition for a growing population it will be necessary to expend food production faster than population growth. From the first transgenic tobacco have been planted in 1992 and the first approval for commercial sale of trans-genie tomato in 1994 in USA, to now more than 48 transgenic crops product have been approved for commercialization. During the twelve year period 1986 do 1997, approximately 25,000 transgenic crop field trails were conduct globally on more than 60 crops with 10 traits in 45 countries. Of this total 60 percent was conduct during the period 1986-1995, and 40 percent in the last two year period 1996-1997. The most frequent crops tested in trails were corn, tomato, soybean, canola, potato, and cotton and the most frequent traits were herbicide tolerance, insect resistance, product quality and virus resistance. During 1997 transgenic crops all around world were grown on 12.8 ha.
Key words: transgenic crops, field trails, biotechnology, insect resistance, herbicide tolerance

DEVELOPMENT AND APPLICATION OF TRANSGENIC PLANTS RESISTANT TO
INSECTS
by
SNEŽANA MLADENOVIĆ DRINIĆ, G. DRINIĆ
SUMMARY
Despite all efforts to prevent pre and post harvest crop losses, insects are destroying 20-30% of all world production. New option to control insect losses is growing of insect resistent crops. The ability to move genes encoding "natural" insecticidal proteins from soil bacteria Bacillus thuringiensis into plants is permitting the development of crops intrinsically resistent to insect attack, with advantages over conventional insect-control agents. Induced resistance through Bt is one of the first crop biotechnology applications where products have already reached market. Twenty one of the 80 crops approved or pending approval is Bt transgenic crops dominated by corn and followed by potato and cotton. In 1997, the global area of transgenic was 12.8 million ha with Bt crops on 4.,0 million ha.
Key words: insects, Bt, resistance, transgenic plants, biotechnology

HETEROSIS IN CORN BREEDING
by
M. STOJAKOVIĆ, Đ. JOCKOVIĆ, G. BEKAVAC, ALEKSANDRA NASTASIĆ
SUMMARY
The term heterosis has been introduced to explain an increase in vigor of crosses between genetically divergent garnets (Shull, 1952).
Numerous hypotheses have been developed to explain the nature of this phenomenon. Partial or complete dominance on additive manner contribute to the heterosis in corn predominantly Hence, heterotic effect depands on frequency of dominant alleles dispersed over the genome (Lonnquist, 1980). It doesn't preclude overdominant effect at some loci, but the role of overdominance in corn heterosis is of minor importance.
Before the hybrid seed is produced inbred lines should be classified into the heterotic groups according to their hybrid performance. European dent or flint type by USA dent type are common het erotic pair in Europe, while the Reid Yellow Dent by Lancaster Sure Crop is the most frequently used heterotic pair in moderate climate in the world.
Heterotic effect in hybrid crosses is caused by genetic differences of the parents. Genetic distances between corn inbred lines were detected by molecular markers. A close correlation between inbred line RFLP diversity analysis and pedigree analysis were established, but reliable method for hybrid yield potential prediction hasn't been found yet (Lee et all., 1989; Melchinger et all., 1990).
Key words: Zea mays, heterosis and heterotic groups, hypothesis, heterotic pattern

AN INVESTIGATION ON MAIZE SEED VITAL FUNCTIONS BY NON-INVASIVE METHODS - RESONANCE RAMAN SPECTRA OF CAROTENOIDS IN THE MAIZE
KERNEL MEMBRANE
by
Č. RADENOVIĆ, M. JEREMIĆ, G.V. MAXIMOV, M. MIŠOVIĆ and D. SELAKOVIĆ
SUMMARY
Vital functions of foundation and hybrid maize seeds under atypical agroecological growing conditions, such as the ones in the northern countries or mountainous regions were studied by the resonance Raman spectroscopy. This method is suitable for estimation of maize seed resistance to unfavourable environmental factors at planting.
A characteristic resonance Raman spectrum for maize seed - the kernel was experimentally in vivo determined. The four principal spectral bands of the resonance Raman spectrum of different intensities were formed at four various frequencies. Vital functions of the investigated maize seeds were evaluated by the analysis of these spectral bands.
According to presented results and results of the previous studies it is possible to discuss vital functions not only from the aspect of injuries, but also from the aspect of conformational changes the carotenoid molecule of the maize seed membrane leads to the estimation of seed injury intensities at planting. Critical temperatures were also determined: 11 °C, 13 °C, 14 °C and 16 °C for SL, SHj, SH2 and SL9, respectively.
Key words: seed, maize, resistance, stress, temperature, spectroscopy, spectral band, raman's frequency, structural changes

POSSIBILITIES OF UTILISATION OF MODIFIED INBRED LINES IN HYBRID
MAIZE SEED
by
PAVLOV M.
SUMMARY
Nowdays Yugoslavia is one of the most important hybrid maize seed producers in the world. Single-cross hybrids are prevalent in this production. The seed production in these hybrids is very difficult and risky, especially under unfavorable conditions, due to lower yielding of a female component. This study is an attempt to answer the question whether the high and stable seed production can be obtained by the utilization of modified inbred lines through the yielding increase of female components.
Based on the gained results it can be concluded that the sister lines and bac crosses are much bet ter in the hybrid seed production. On the average, the yield increase of sister lines and back crosses in relation to inbred lines amounts to 30.71% and 20.49%, respectively
The average yield of F1 hybrids amounted to 12.82 t/ha, 13.16 t/ha and 13.36 t/ha for standard, sister and hybrids derived by back cross of female components, respectively
According to obtained results, it can be concluded that Fj hybrids developed by utilization of modified inbreds as female components, maintain the yield and phenotypic properties of the original hybrids with significant economic advantage in the seed production.
Key words: maize, inbred lines, sister lines, back crosses, hybrids, hybrid seed, yield

GENE EFFECTS ON OIL CONTENT IN MAIZE (Zea Mays L.)
by
ROŠULJ M., SARATLIĆ G.
SUMMARY
Two inbred lines with different oil content were used in the study: The inbred line Du809 with high and the inbred line B73 with low oil content. The effect of additive, dominant and epistatic gene for oil content in seed was investigated by the generation mean analysis method related to two parents and their progenies (F1, F2, BC1 and BC2). Comparative field trials with parents and their progenies were planted at Zemun Polje and Inđija during 1994, in randomised complete block design with six replications and a density of 62,111 plants ha"1. According to obtained results, the additive gene effect was highly significant in both locations. The dominant gene effect was significant and several times lower than the additive gene effect. Epistasis did not contribute significantly to the inheritance of the oil content. Comparing gene effects in different environments shows no significant genotype x environment interaction.
Key words: maize, oil content, generation mean analysis, gene effect

EFFECT OF GENOTYPE ON THE LENGTH DEVELOPMENTAL STAGES AND DRY MATTER ACCUMULATION ON MAIZE KERNEL (Zea Mays L.)
by
LOPANDIC DRAGISA
SUMMARY
Grain filling and dry-down rates maize inbreds and hybrids of different length of the growing season were observed in this study. Seven inbreds of different genetics base and FAO maturity group 200-500, crossed according to the HS method (with A 654 as a common parent) were selected for the study. Analyses of dry matter content in grain were during different stages of milk line formation and after physiological maturity (appearance of black layer on kernel) the analyses were done every ten days till the harvest. Obtained results point out that the inbred A 654 had highest rate of dry matter accumulation during grain filling, while A 654 x M 432 ranked first among hybrid combinations. The determined dynamics of daily accumulation of dry matter in studied genotypes proves the lessen the risks from maize growing under stress conditions (drought, earlier occurrence of autumnal frost, shoter growing season).

THE EFFECT OF ENDOSPERM TYPE ON SEED GERMINATION
OF MAIZE (Zea Mays L.)
by
PAJIĆ ZORICA, POPOVIĆ RADMILA, ŠATARIĆ I.
SUMMARY
Studies were performed under field and laboratory conditions to determine the effect of favorable and unfavorable factors on germination and emergece rate of maize seed, i.e. viability of seed of different endosperm. Five genotypes of different endosperm textures were used in the studies: standard grain quality hybrid (dent), pop corn hybrid, sweet corn hybrid with sugary (su) gene and sweet corn population with shrunken-2 (sh-2) gene or a "super-sweet" population. The obtained results indicate differences in seed germination capacities of observed genotypes. The best germination and early emergence were detected in the standard grain quality hybrid, while the worst germination was determined in the "super-sweet" population. These differences are probably a result of endosperm texture (type), grain weight, sugar and starch content in endosperm, thickness and structure of pericarp.
Key words: endosperm type, standard grain quality hybrid, pop corn, sweet corn, "super-sweet", germination

EFFECTS OF HERBICIDES ON QUALITY OF MAIZE INBRED LINE SEEDS
by
MILIVOJEVIĆ M., ŽIVANOVIĆ M., ĐUKANOVIĆ LANA, STEFANOVIĆ LIDIJA, DRINIĆ G.
SUMMARY
The effect of applied herbicide combinations on quality of maize inbred line seeds was observed in the present study. The thirteen maize inbred lines (PL-Ill, 110, 16, 80, 121, 82, 106, 46, 146, 159, 143, 8 i 12) were treated by the following herbicide combinations: EPTC- dihlormid + atrazine (Eradicane-6E+Atrazin) (T-l), alachlor + linuron (Afalon combination) (T--2), prosulfuron + primisulfuronmetil +adjuvant (Ring + Extravon) (T-3), rimsulfuron + pyridate + atrazine + adjuvant (Tarot + Clap + Citovet) (T-4). The fifth variant was a non-treated check (K). The trials were set up in a randomised complete-block design experiment with three replications in the fields of the Maize Research Institute in Zemun Polje. After harvest, seeds of treated and non-treated maize inbred lines were analysed in the laboratory according to the ISTA Rules. Obtained results were analyzed by the three factorial analysis of variance, while the significance of differences for certain factors and their interactions were determined by both F and t-tests.
Reductions of 1000-kernels weight and germination viability due to the effect of applied herbicide combinations were on the average highly statistically significant for all 13 inbreds. Germination viability varied significantly over all inbreds except in the inbred PL-80, in which Ring affected all traits very adversely. Significant differences were also detected these genotypes, locations, as well as over interactions between genotypes and locations and genotypes and herbicides.

YIELD STABILITY OF MAIZE HYBRIDS FAO 100-300 GROUP OF MATURITY
by
DRAGICA SIMIĆ, BOŽANA PURAR, D. JOCKOVIĆ, G. BEKAVAC and R. POPOV
SUMMARY
Yield stability of early maize hybrids FAO 100, 200 and 300 group of maturity was studied on 3 locations in 1996. Stability parameters were performed according to the model of Eberhart and Russell, 1966. Sperman's rank correlation between grain yield and regression coefficient bi and standard error of arithmetic mean of regr^ sion coefficient bi were calculated. Significant differences of grain yield and stability parameters were obtained among hybrids of different groups of maturity, hybrids of the same group of maturity and locations.
Middle early FAO 300 hybrids achieved higher yields (average 11.96 t∙ha-1) than very early hybrids FAO 100 (average 10.43) and early FAO 200 hybrids (average 10.63 t-ha-1). Hybrid NS 300 gave the highest grain yield (14.14 t∙ha-1), the same hybrid was better adapted to the favourable growing conditions and the coefficient of regression was higher than unit.
Taking in consideration the yield and stability parameters the hybrids: NS 184, NS 251 and NS 303 were the best u FAO 100, 200 and 300. On the basis of values of standard error average regression coefficient (bi) the highest heterogeneity of values (Sbi) were obtained for FAO maturity group of 100 (Sbi=0.635), while heterogeneity of values Sbi for hybrids FAO 200 and 300 were smaller (Sbi-0.469 and 0.412).

ASSESSMENT OF POTENTIAL VIGOUR AND PRODUCTIVITY
OF AIR-DRIED CUCUMBER SEEDS BY THE APPLICATION
OF LUMINESCENCE METHOD
T. V. VESELOVA1, V. A. VESELOVSKY2 and E. A. LEONOVA3
ABSTRACT: Delayed luminiscence (DL) from air-dried seeds of different plants has been already observed. It has been noticed that the seed DL level increases with the moisture content decreasing. The seed DL level also increases with the decreasing germination percentage. Therefore it seems reasonable to suggest that the DL level rise with seed ageing is induced by the moisture content reduction. Within the range of 12 to 85% RH all equilibrated viable seeds have high water content and low DL level. Dead seeds have low water content and a high DL level. As the DL method is highly sensitive, it allows measuring of the DL level of both individual seeds and seed lots and therefore allows construction of the seed distribution according to their DL level. There are three maxima (three seed fractions) in the distribution of a seed lot, containing seeds of various germination percentage. The first fraction is the fraction of viable seeds. The second fraction involves viable seeds with a lower vigour; while the third fraction encompasses only dead seeds. The distribution of seedlings according to their root length has two maxima (long and short root length fractions). The shape and position of these two maxima coincides with that of the distribution curve (the first and the second fractions) of air-dried seeds according to their DL level. The correlation between the potential productivity and the DL level of air-dried seeds has been established in cucumber seeds.
Key words: accelerated ageing, delayed luminiscence, potential productivity, seeds, unusual (paradoxical) effect
Abbreviations -DL- delayed luminiscence, RH - relative humidity

EFFECT OF SELFING ON SEED AND POD SET IN ALFALFA
by
S. KATIĆ, V. MIHAILOVIĆ, I. PATAKI
SUMMARY
In the period from 1984 to 1996, a large number of alfalfa varieties were studied for reaction to selfing.
Pod set per flower seed set per pod, and seed number per flowers were monitored in field conditions in the S0, S1, S2 and S3 generation of selfing. The highest values of pod and seed setting were obtained in the non-inbred plants (S0). The corresponding values in the S1, S2 and S3 generation were significantly lower. Differences in the values of seed and pod setting among the S1, S2 and S3 generation were insignificant. Inbreeding depression was most pronounced in the first generation of inbreeding (S0). The depression did not increase progressively in the subsequent generations.
Significant correlation were found in the inbred alfalfa between pod number and seed number per flower and between seed number per pod and seed number per flower

THE ROLE OF BREEDING AND SEED PROCESSING IN FIELD CROPS QUALITY
ASSURANCE
by
B. VULIĆ, BRANKA BUKVIĆ
SUMMARY
Quality is the category which is to be strategically planed for agriculture. An aspect of agricultural products quality assurance gives a very important role to the breeding and seed processing in customer-supplier chain. Guidance of breeding is aimed by customer’s requirements (food industry, processing industry, users - consumers, nutritionists, society etc.). The role of breeding includes all functions of an institution in quality management and process of customer’s requirements satisfying begins 10-20 years before the product meets the buyer. Successful models for systematizing necessary activities and managing their quality are offered by series of international standards ISO 9000. This way, by correct long-term planning, breeding becomes a part of agricultural and food strategy.
Seed processing, as a continuation of a breeding process, provides enough seed for agricultural production. But, not just enough, but quantities of exact quality, adequate to customer’s requirements. This way, seed processing becomes a part of agricultural strategy too, unavoidable link of customer -supplier chain.
This paper describes the role of field crops breeding and seed processing in quality assurance of agriculture.
Key words: quality assurance system, breeding, seed processing
