AB  - Continental halophytic grasslands are known for performing of range of ecosystem services especially remarkable in the regions where they are much distributed – in arid and semi-arid areas. Continental halophytic grasslands of the Central and South-East Europe are not considered as favourable for arable farming, however, traditional animal husbandry plays a crucial role in maintaining biodiversity and preserving these natural habitats. The particular interest of this study is the assessment of the chemical composition of biomass and the quality of insufficiently studied halophytic grassland communities of the central Balkans. In addition, the differences in pastoral value were monitored along the geographical gradient, i.e., between grasslands situated in the Pannonian plain (grasslands of Alliance Puccinellion limosae) and those distributed on the south Serbia (Alliance Festucion pseudovinae). The study was carried out at 18 representative sites, focusing on the saline grasslands of the two distinct regions – on the north and on the south of Serbia. The obtained results show that the halophytic grasslands have satisfying quality characteristics (average values: dry matter - 93.67%, crude protein - 8.66%, cellulose - 30.36%, crude fat - 2.27%) compared with other studied grasslands of saline habitats. There were no significant differences in quality and chemical composition of grasslands of the two regions, despite differences in floristic composition, indicating that salinity is the key determinant for pastoral value of the halophytic vegetation. The certain variations were attributed to the specific floristic composition related to ecological conditions and halophytic community characteristics.

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  - The aim of this paper was to evaluate the agronomic value of red clover (Trifolium pratense L.) wild populations. The analyzed material was gathered on the territory of Serbia and it was estimated which populations could be involved in the breeding program. 17 red clover populations were included in the research. Investigation was carried out at the experimental field of the Institute for forage crops, Krusevac, Serbia. The field trial was performed during three years (2008 - 2010) when data about morphological (green mass, dry mater, plant height, number of stems, number of lateral branches, number of internodes, length and width of a middle leaf lamina) and basic chemical parameters (quantity of crude proteins, crude fiber, ash, fat, NFE) were collected. In this paper, results of the research were processed by application of analysis of variance (ANOVA) and multivariation methods. Cluster analysis based on morphological traits resulted in formation of three clusters and the traits with the largest influence on grouping were: green mass, plant height, length and width of a leaf. Principal component method confirmed this separation and resulted in even more clear grouping of populations. Cluster analysis and PCA method were also applied to the traits of dry matter quality, when four clusters were formed, and the traits with the largest influence on grouping were percentages of protein, fat and fiber. Using both set of traits and several types of analyses contribute to grouping of populations which promise most and whose positive traits such as: high green mass yield, number of stems as well as the percentage of proteins can be combined for the purpose of getting synthetic varieties.

AB  - In a two-year field trial, four alfalfa cultivars grown in all combinations with five strains of Sinorhizobium spp. were assessed for N-2-fixing potential and compatibility of symbionts with the aim to co-select plant and rhizobia as alternative approach to symbiotic N-2 fixation improvement. It was found that rhizobial strains, host cultivars and interactions between them had a highly significant effects on shoot dry weight (SDW), total and fixed N content of alfalfa. A significant variation in N-2 fixation effectiveness of rhizobial strains, from ineffective to significantly effective depending on cultivars and year of utilization was detected. Effective strains increased SDW by 49-114% (2010) and 35-86% (2011). In the first year the highest effectiveness had strain L5 with cultivars K-28 and BL-88 and strain L3Si with BL-88 while in the following year all applied strains were effective with different extent. Only one strain (L5) was effective with most of alfalfa cultivars over a two-year period. Percentage of N-2 fixed in plant mass for strain L5 was 33% in 2010, and 38% in 2011. In addition, one cultivar (BL-88) was identified to have superior symbiotic performances, exhibiting its high capacity for N-2 fixation. Results indicate that simultaneous selection of both symbionts should be applied for improvement of N-2 fixation in alfalfa.

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.

abstract = "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., 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.",
