Two varieties and 9 hybrids of black chokeberry have been studied for 2001-2005. The study was connected with phenology, number of berries in raceme, fruit size, crop yield, and biochemical compound of fruit. All the studying hybrids showed potential in the fruit weight, productivity, winter hardiness, large-sized, biochemical compound of fruit in the conditions of Belarus. Hybrids A-110, A-48, A-100 were marked. Among varieties with high yielding and raceme filling by berries variety Venisa has been marked. On average for research years on crop yielding the following hybrids were distinguished: A-48 (3,2 kg/bush), A-12 (2,4 kg/bush), A-18 (2,1 kg/bush). The average mass of 100 berries was higher than at hybrids A-46 (107,2 g), A-48 (103,6 g), a-12 (103,2 g), and raceme filling by berries – A-48 (13 units), A-100 (13 units ), A-46 (12 units), A-18 (12 units), A-12 (12 units). On the average for the research years the soluble dry matters content at varieties has been 14,21-14,97%. The same index at hybrids has been much more – 15,05 – 16,15%. In accordance with this index the hybrids A-110 (16,15%), A-100 (16,09%), A-48 (16,08%) were pointed out. Acid accumulation has been occurred within 1,03 up to 1,17%. Significant distinctions between varieties and hybrids were not found
