The six generations (P1, P2, F1, F2, BC1 and BC2) of twelve cross combinations of pigeonpea (Cajanus cajan L.) were studied during 2003-2006 for days to 50 % flowering, days to maturity, plant height, number of primary branches, number of secondary branches, pods per plant, pod length, number of seeds per pod, 100-seed weight, harvest index and seed yield per plant. The means of six generations were subjected to detect main gene effects and interactions. The estimates of six parameter model revealed that both additive and dominant gene effects were important in all the crosses for almost all the traits. However, the relative contribution of dominant gene effects was much higher than additive gene effects for plant height, pods per plant and seed yield per plant. Higher frequency of duplicate type of epistasis also confirms the prevalence of dominance gene effects for above traits except for seed yield per plant.
