An 8 x 8 diallel cross mating design with the parents and F1s was used to estimate gene action and combining ability for yield and yield attributing traits in sesame (Sesamum indicum L.). Combing ability analysis revealed predominance of non- additive gene action for all traits viz,. days 50% flowering, days to maturity, plant height, number of branches per plant, number of capsules per plant, length of capsule, width of capsule, 1000 seed weight, yield per plant and oil content which can be improved by bi-parental mating or reciprocal recurrent selection. The parent AKT-306, LOCAL and G-1 were found as good combiner for seed yield per plant. The highest SCA effect for seed yield per plant was exhibited by cross G-1 x IC- 204025 along with superior SCA effect for five characters like plant height, number capsule per plant, seed per capsule, capsule length and capsule width. The character test weight had fixable additive genetic variance which can improve by simple selection. The crosses AKT-306 x YLM-17 and LOCAL x AKT-101 with significant SCA effects indicating the predominance of additive gene action for seed yield hence progeny selection in the segregating generation is more useful.
