Genotypes which were grown under rainfed conditions differed significantly in their developmental pattern. Genotypes, Sel. U24 X A1 and Sel 554 x A2 which produced maximum number of flowers 25 days after flower initiation, produced maximum yields. Seed yield was significantly correlated with total number of flowers produced during 21 to 30 days after flower initiation (r-0.885), maximum pods set (r=0.871), and pods at harvest (r=0.969).
