Abstract
Taking into consideration the importance of alfalfa as a fodder plant breeding for increasing the genetic seed yield potential is necessary due also to relatively low and uneven seed yields. The aim of the paper was to based on the analysis of yield and yield components choose genotypes with differences in the characteristics examined in order to use them in further investigation as the starting material for hybridization for the purpose of increasing the seed yield potential. In five selected alfalfa genotypes the following was analyzed: the number of inflorescences per stem, the number of pods per inflorescence, the number of grains per pod and seed yield per plant as well as seed quality parameters (1000-grain weight, germination energy, germination and hard-grain percentage). The highest number of inflorescences per plant was registered in the genotype 9 (8.82), the highest number of pods per inflorescence (8.35) and the highest seed yield per plant (6.89 g) were recorded in the genotype 2. The number of grains per pod was relatively even in all genotypes. The genotypes examined were characterized by high germination energy, germination and 1000-grain weight. As the chosen genotypes (1, 2, 4, 6 and 9) had relatively high variability in the properties examined, they were selected to be parents for diallel crossing or the starting material for breeding of this species for increasing the genetic seed yield potential.
