Genetics of protein content in 9 diverse varieties of pigeon pea (Cajanus cajan L. Millsp.) was studied through diallel analysis of F, and F2 generations. The study revealed that both g.c.a. and s.c.a. variances for protein content were highly significant The magnitude of additive and non-additive components of variance further confirmed the importance of additive as well as nonadditive gene action In F1 the non-additive component was predominant while in F2 the additive and nonadditive components were of equal importance. This showed that predominance of nonadditive gene action in F, analysis may be due to upward bias due to linkage Out of the parents, Baigani showed the highest protein content (23–22 and 23–25%) in the two seasons and had the highest g.c.a. effects
