AB  - The content of daidzein, genistein, formononetin, and biochanin A isoflavones was studied in natural populations of red and Hungarian clover, to estimate their impact on fodder quality and to determine directions in possible breeding programs. The study included 6 red clover (Trifolium pratense) and 6 Hungarian clover (Trifolium pannonicum) populations, collected in the central Balkans. The differences between the species and among the populations were analysed. The average content of total isoflavones was 1.393 mg g–1 and 0.487 mg g–1 of air dry matter in Hungarian clover, respectively. While the most prevailed isoflavone in red clover was biochanin A (46%), the Hungarian clover populations were rich in genistein (43%). The red clover leaves accumulated the highest content of isoflavones. The Hungarian clover flowers and leaves had an equal amount of isoflavones. The obtained values of the total isoflavones could not affect the overall nutrient quality and therefore, researched natural populations of two clover species could be considered for further breeding programs.

AB  - In limited growing conditions, intercropped field peas and oats can represent a significant source of forage rich in protein. If applied correctly, factors such as nitrogen fertilizer, the mowing phase, and sowing norms can significantly increase the productivity of these mixtures. Field trials were conducted to examine their productivity under different nitrogen levels (0, 40, 80 kg ha−1 ), different sowing norms/mixtures (field peas: oats—100:15%; 100:30%), and two stages of growth (full flowering, full pod formation). Nitrogen fertilizer and different sowing norms had a significant effect on the biomass, hay, and crude protein yields. On average, the highest hay yields were achieved with 80 kg ha−1 N (4.96 t ha−1 ), followed by 40 kg ha−1 N (4.27 t ha−1 ). The highest protein yields were achieved with 40 kg ha−1 N (CP—704.1 kg ha−1 ), followed by 80 kg ha−1 N (CP—637.6 kg ha−1 ). Sowing norm 100:30% achieved higher hay yields: 100:30%—4.82 t ha−1; 100:15%—4.44 t ha−1, while 100:15% achieved higher crude protein yields: 100:15%—730.4 kg ha−1; 100:30%—692.7 kg ha−1 on average. The costs were not significantly increased with the nitrogen fertilizer, but the net profits were increased by as much as 163%, depending on the nitrogen level and the mixture. Nitrogen fertilizer also achieves higher economic efficiency for the mixture 100:15% compared to the 100:30% mixture. Mixtures of field peas and oats outperform single-grown crops and provide cost-effective feed for a short time. Using optimal seed ratios and nitrogen fertilizer can significantly increase the productivity and profitability of the feed with minimal impact on the overall production costs.

AB  - Due to historical BACKGROUND:  of vegetation development, geographical position, climate and relief, Serbia represents one of the 158 world biodiversity centres, based upon the number of plant species and territory size (biodiversity index 0.72). Large areas in Serbia are under natural grasslands and pastures, composed of forage grass species, and important as source of natural plant genetic diversity and germplasm for breeding. These eco-systems represent basic prerequisites for sustainable forage production, but very low potential of them is utilized and genetic resources are not protected. Family Poaceae is present in Serbia flora with 70 genera and among them from the aspect of forage production and quality, the most important are perennial Festuca, Lolium, Dactylis, Phleum, Bromus, Arrhenatherum, Poa and Agrostis species. Most of these grasses have been bred in Serbia and lot of cultivars were released. These cultivars contain autochthonous Serbian material and represent great and important resource of genetic variability. Therefore, collecting of new samples which are acclimatised to local eco-geographical conditions and including them in plant ex situ gene bank is of exceptional importance for further utilization in different plant breeding programmes as well as genetic resources protection. These autochthonous populations have natural variability and very often have satisfactory yielding performance in comparison with introduced cultivars, which referred them for direct phenotypic selection for cultivars release. Broadening of forage grasses genotypes collection is permanent objective of Serbian scientists. Collected accessions are being characterized and evaluated for important phenological, morphological and agronomical traits. In this paper genetic resources of forage grass species, their diversity and potentials, state of the grasses gene banks, as well as possibility for breeding of new cultivars has been analysed.

AB  - Products of metabolism that are directly involved in growth, development and reproduction and also secondary products of metabolism were studied in 16 natural populations of three species of the genus Trifolium (T. repens - four populations, T. alpestre - three populations, T. pannonicum - nine populations), collected from the central Balkans region, i.e. territory of Serbia. Statistical analysis showed the presence of variability in all species of the test material. The best quality of dry matter, estimated by the ratio of crude protein and crude fiber, was achieved in the populations of white clover. In this species, average protein content was 216.4 g kg(-1) while the average content of crude fiber was 222.4 g kg(-1). The highest average content of total phenols (77.9 mg GA g(-1)), flavonoids (159.7 mg Ru g(-1)) and antioxidant activity (70.2 mu g ml(-1)) was measured in populations of T. pannonicum by phytochemical analysis of aerial parts of plants. The content of secondary metabolites and antioxidant activity in other species were extremely low. Populations of T. pannonicum were notable for fodder quality and antioxidant activity: CS091 with 186.2 g kg(-1) of crude protein and antioxidant activity of 55 mu g ml(-1); RA123 with 175.6 g kg(-1) of crude protein and a high level of antioxidant activity of 44.8 mu g ml(-1). It can be concluded that the selection of these populations may lead to creation of different varieties of fodder crops that could give safe animal feed and would be suitable for growing under adverse conditions of mountainous climate.

AB  - The aim of this study was to examine genetic variability, heritability and correlation of seed yield components and seed yield of progenies of autochthonous populations and cultivars of perennial ryegrass, and that on the basis of these results distinguish genotypes that would be later used in the creation of new local cultivars of perennial ryegrass. Research was carried out on experimental fields and laboratories of the Agricultural Institute of Republic of Srpska in Banja Luka in 2007. and 2008., on 6 natural populations of perennial ryegrass collected in Bosnia and Herzegovina and two cultivars, Maja and Calibra as standard. Following parameters were analyzed: number of generative tillers per plant, time of flowering, spike length, number of spikelets per spike, seed yield per spike and plant and 1000 seed weight. Analysis of the results of the number of generative tillers per plant indicates a statistically significant difference in the studied populations and cultivars of perennial ryegrass. The highest average number of tillers per plant was found in the cultivar Maja (193.8), and the least number was detected in population Dragočaj (78.9), so statistical differences were highly significant. The longest period to beginning of flowering was determined in cultivar Calibra (56.5 days) and the shortest in population Laminci (43 days). The average length of spike of perennial ryegrass in the studied population was 22.78 cm and was significantly lower than cultivar Maja. Statistically significant differences between populations and variety Maja in the number of spikelets per spike were detected. The average seed yield per spike of studied populations was in level with cultivar Maja and 37.5% higher compared with variety Calibra. In the studied populations of perennial ryegrass seed yield ranged from 5.21 g (Dragočaj population) to 15.40 g (Kupres population). Weight of 1000 seeds was highest in the variety Calibra (2.60 g) and lowest in population Maglajani (1.94 g). Proportion of genetic to phenotypic variance for time of flowering, the number of generative tillers, seed yield per spike and plant and 1000 seed weight indicate that the variability of these traits in this collection of genotypes, largely derived from plant genotype.

abstract = "The aim of this study was to examine genetic variability, heritability and correlation of seed yield components and seed yield of progenies of autochthonous populations and cultivars of perennial ryegrass, and that on the basis of these results distinguish genotypes that would be later used in the creation of new local cultivars of perennial ryegrass. Research was carried out on experimental fields and laboratories of the Agricultural Institute of Republic of Srpska in Banja Luka in 2007. and 2008., on 6 natural populations of perennial ryegrass collected in Bosnia and Herzegovina and two cultivars, Maja and Calibra as standard. Following parameters were analyzed: number of generative tillers per plant, time of flowering, spike length, number of spikelets per spike, seed yield per spike and plant and 1000 seed weight. Analysis of the results of the number of generative tillers per plant indicates a statistically significant difference in the studied populations and cultivars of perennial ryegrass. The highest average number of tillers per plant was found in the cultivar Maja (193.8), and the least number was detected in population Dragočaj (78.9), so statistical differences were highly significant. The longest period to beginning of flowering was determined in cultivar Calibra (56.5 days) and the shortest in population Laminci (43 days). The average length of spike of perennial ryegrass in the studied population was 22.78 cm and was significantly lower than cultivar Maja. Statistically significant differences between populations and variety Maja in the number of spikelets per spike were detected. The average seed yield per spike of studied populations was in level with cultivar Maja and 37.5% higher compared with variety Calibra. In the studied populations of perennial ryegrass seed yield ranged from 5.21 g (Dragočaj population) to 15.40 g (Kupres population). Weight of 1000 seeds was highest in the variety Calibra (2.60 g) and lowest in population Maglajani (1.94 g). Proportion of genetic to phenotypic variance for time of flowering, the number of generative tillers, seed yield per spike and plant and 1000 seed weight indicate that the variability of these traits in this collection of genotypes, largely derived from plant genotype. In this investigation, the presence of a highly significant positive genetic correlation was found between time of flowering and spike length (0.98), time of flowering and 1000 seed weight (0.97), number of generative tillers and seed yield per plant (0.91) and spike length and 1000 seed weight (0.98)., Cilj ovog rada je da se ispitaju genetička varijabilnost, heritabilnost i korelacije komponenti prinosa i prinos sjemena potomstava autohtonih populacija i sorti engleskog ljulja.

AB  - Due to specific climatic conditions, perennial ryegrass breeding in Serbia is focused on resistance or tolerance to abiotic stress factors, especially to drought and high temperatures. These traits should be associated with high dry matter yield and quality. Therefore, most frequently used initial material is autochthonous populations and ecotypes adapted to local agro-ecological conditions, but knowledge about their variability of important traits for breeding is missing. Pre-selection evaluation of ten populations of perennial ryegrass originating from Serbia is presented in this paper. Twenty five traits were investigated during the two-year period and processed using analysis of variance and multivariate statistical methods (cluster and principal components analysis). The goal was to determine diversity and genetic distances of investigated populations by phenotyping and to define traits considerably affecting the variability and discrimination of populations. On cluster diagram two groups of population are observed, but geographic origin of populations (lowland, hilly, mountainous habitat) was not influence to clustering of collection. Factor analysis has clarified that first seven principal components (PC) described almost 95%. The traits which show high correlation coefficients with first principal component were plant height in first cut, leaf length and width, DM of generative tillers, spike and spikelet length and 1000 seed weight, and with second principal component time of heading, terminal internode length, DM of vegetative tillers, spikelet number and FSU. It can be concluded that variability between populations was high and that differences of population were mainly affected by most important traits for breeding, such as components of dry matter production and some seed yield components.
AB  - Usled specifičnih klimatskih uslova, oplemenjivanje engleskog ljulja u Srbiji je fokusirano na toleranciju abiotičkih faktora stresa, posebno na sušu i visoke temperature. Stoga se kao početni materijal u oplemenjivanju najčešće upotrebljavaju autohtone populacije i ecotipovi prilagođeni lokalnim agro-ekološkim uslovima. Međutim saznanja o varijabilnosti najvažnijih osobina kod autohtonih populacija su vrlo ćesto oskudna. U ovom radu su predstavljena proučavanja varijabilnosti osobina deset populacija engleskog ljulja poreklom iz Srbija. Dvadeset pet osobina je ispitivano tokom dve godine, a podaci su obrađeni analizom varijanse i multivarijacionim statističkim metodama (PCA i klaster analiza). Cilj je bio da se utvrdi raznovrsnost i genetička udaljenosti ispitivanih populacija fenotajpingom i da se definišu osobine koje značajno utiču na varijabilnost i grupisanje populacija. Klaster analizom utvrđene su dve grupe populacija, ali geografsko poreklo populacija (ravničarska, brdska i planinska staništa) nije uticalo na pomenuto grupisanje. Faktorska analiza je pokazala da prvih sedam glavnih komponenti (PC) opisuje 95% varijabilnosti. Osobine koje pokazuju visok koeficijent korelacije sa prvom glavnom komponentom su visina biljaka u prvom otkosu, dužina i širina lista, suva materija generativnih izdanaka, dušina klasa i klasića i težina 1000 semena. Utvrđena je visoka varijabilnost između populacija koja uglavnom potiču od oplemenjivački najvažnijih osobine, kao što su komponente prinosa suve materije i neke komponente prinosa semena.
