A 6 x 6 diallel combining ability analysis in pigeonpea showed the predominant role of nonadditive gene action for seed yield perplant. Numberof pods and seeds/plant had equal importance of both additive and nonadditive genes. Genotypes No. 148 and T 21 exhibited significant and positive gca effects for seed-yield, pods and seeds/plant. Two crosses, ICPL 86007 x No. 148 and ICPL 86012 x No. 148, had positive and significant sca effect for seed yield, and pods and seeds/plant.
