Diallel analysis for seed size on 10 varieties of pigeon pea or arhar Cajanus cajun L. Millsp., representing different maturity groups and wide range of variability in seed size, was conducted to determine genetic parameters. The D and H, components indicated a predominance of additive gene effects and the degree of dominance was in the partial dominance range. Seed size was simply inherited with a high heritability value of 0.82. The scatter of parental arrays in a W r' V r graph suggested that the genes controlling smaller seed size were dominant over the genes controlling larger seed size. The analysis indicated the possibility of improving seed size by simple selection procedures.
