From different pollination combinations of cultivar Bagrina, seed germination, vitality and vigour of seedling, like theirs growth uniformity, were investigated in the beginning and at the end of vegetation. Cultivars Chardonnay, Smederevka and SV 12-375 were used as pollenizers, and besides controlled pollination, open pollination of cultivar Bagrina was examined, as well. From all 4 crossing combinations, seeds had relatively low germination (3.8%-12.4%), while seedlings vitality was high (84.5%-91.7%). In dependence of pollenizer, differences in vigour and uniformity of properties in obtained seedlings, were established. In crossing combinations Bagrina x Smederevka and Bagrina x Chardonnay existed very significant correlation between plant height at the beginning and at the end of vegetation, as well as between internode length at the beginning and at the end of vegetation, while it was not the case in other two combinations (Bagrina x SV 12-375 and Bagrina x Open pollination).
