Abstract
Seed yield and seed yield components (stem height, number of stems per m(2), panicle branches) and quality of alfalfa seed (germination and mean seed weight), were studied for 3 years of research. Three cultivars of alfalfa from Serbia (NS-Slavija, NS-Medtjana and Zajecarska 83) and French cultivar Europe were observed. In the sowing year, the highest variability was determined for seed yield (CV=56.6%) and percent of dormant seed (CV=19%), while other traits showed low variability. The lowest variability was determined for seed germination (CV=0.2%). In the 2nd and 3rd year, the highest variability was determined for percent of dormant seed (B-1 CV=13.6% and 132 CV=13.7%) and for seed yield (B-1 CV=7.4% and B-2 CV=17.5%). Other investigated traits expressed low variability. The lowest variability was expressed in seed germination (B-1 CV=1.0% and B-2 CV=0.6%). Seed germination is in very strong positive correlation with yield (r=0.90). Number of secondary shoots in correlation with yi...eld showed almost complete negative correlation (r=-0.94).
