Abstract
The gene lp, governing long raceme peduncle and great number of flowers in inflorescence, was used for improvement of seed yield potentials of Radius variety. The breeding stock of variety exhibiting superior pod and seed setting was back crossed to the donor of lp gene — mutant line No. 2002/1. After two cycles of back cross 7 long racemed lines were obtained. Five lines were selected to form the new synthetic variety RAH 100. Field trials demonstrated 15–20% higher seed yield of this variety in comparison with the best short racemed standard cultivars.
