Abstract: The experiment was undertaken to study the combining ability for fruit yield and its contributing traits in okra. The experimental material consisted of eleven parents (8 lines and 3 testers) and 24 F₁’s produced from line x tester mating design and evaluated in randomized block design for seven characters. The analysis of variance for combining ability revealed that the SCA variances were higher than their respective GCA variances for all the characters (except number of fruits per plant) confirmed the preponderance of non-additive gene action for most of the traits emphasized the utility of hybrid breeding approach to exploit existing heterosis in okra. The parents EC 169513, EC 30563 and VRO-6 were identified as good general combiners for most of the characters including fruit yield per plant and can be exploited well in further breeding programme. The estimates of sca effects revealed that the two cross combinations EC 169513 × GO-6 and EC 30563 × VRO-6 were observed most promising for fruit yield and some of its related traits which could be used as heterotic hybrids.
