The present investigation was made to study the combining ability and gene action in cowpea. Six lines and three testers were included as parental material. Eighteen hybrids were developed and evaluated in RBD at College of Agriculture, Latur during Kharif season 2019 for 10 characters viz., days to 50 percent flowering, days to maturity, plant height at maturity, Number of branches per plant, Number of pods per plant, Number of seeds per pod, Pod length, 100 seed weight, Harvesting Index, Seed yield per plant. In the investigation line, Kashi Gauri good general combiner for Days to 50% flowering, Days to maturity, Number of branches per plant, Number of seeds per pod, 100 seed weight, Harvesting Index, Seed yield per plant and line UV-5 was found good general combiner for plant height at maturity, Number of branches per plant, Number of pods per plant, Number of seeds per pod, Pod lenght 100 seed weight,. Seed yield per plant. Among the testers Konkan Safed was found good general combiner for Number of seeds per pod, Pod length, 100 seed weight, Harvesting Index, Seed yield per plant. Out of 18 hybrids the, the cross,UV-5 x Konkan Safed was found as best specific combiner for majority of the characters viz. seed yield per plant, number of pods per plant, 100 seed weight in desire direction. The high exhibiting SCA effect for seed yield cross Kashi Nidhi x Konkan Safed also exhibited average SCA effect for number of branches per plant, pod length, number of seeds per pod and 100 seed weight in desire direction. The variance component due to specific combining ability was greater in magnitude than that of general combining ability for all the characters except 100 seed weight, Harvesting Index, seed yield per plant, which indicated that non-additive gene action played important role for the inheritance of these traits and 100 seed weight, Harvesting index, seed yield per plant were governed by additive gene action.
