Combining ability analysis was carried out for fruit yield and its components in okra in a 6 x 6 diallel cross (excluding reciprocals). Both general combining ability (GCA) and specific combining ability (SCA) variances were highly significant for all the characters except days to first flowering and fruit diameter indicating the importance of both additive and non-additive gene actions. However, preponderance of additive gene action was recorded for the traits viz., number primary branches per plant, ridges/fruit and fruit diameter, preponderance of non-additive gene action was recorded for plant height, days to 50% flowering, number of fruits per plant, fruit length, fruit weight and fruit yield per plant. The parents BH-5, BH-1 and BH-2 were found to be the best general combiners and close correspondence between per se performance of parents and their GCA effects were observed. The cross combinations viz., BH-2 x BH-6, BH-1 x BH-3, BH-2 x BH-3, BH-2 x BH-4 and BH-1 x BH-5 showed significant SCA effects in desirable direction for fruit yield per plant and associated characters and were expected to produce transgressive segregants. Magnitude of heterosis over better parent, the best parent was highly significant for total yield per plant. Out of 15 crosses, three crosses over better parent, three crosses over the best parent exhibited positive and significant heterosis for total fruit yield per plant. The hybrid which exhibited maximum heterosis BH-1 x BH-3, BH-1 x BH-4 and BH-1 x BH-5 these hybrids can be commercially exploited after assessing its stability for yield.
