Online published on 21 March, 2016. Abstract An experiment was conducted to analyse the combining ability effect on okra [Abelmoschus esculenta (L.) Moench] during the zaid season of 2012 at the Department of Horticulture, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. All the homozygous parents were sown and maintained by applying the standardized cultural practices. All the morphological characters of the landraces were studied. The experiment was conducted with 21 F1s and F2s developed through diallel hybridization technique excluding reciprocals along with seven parents in a randomized block design with three replications. Okra varieties, KS-387, FB-10 and Azad Krishna, showed good general combining ability(GCA) for yield which appeared to be worthy for exploitation in future hybrid development. It was recommended that the population involving these lines may be developed through multiple crossing isolating high-yielding varieties. The specific combining ability (SCA) effects indicated that choice of parents could be based on the per se performance. The selection in okra crop can be based on the combination of two characters, i e length of first fruiting node with length of fruit and length of fruit with width of fruit, and number of fruits/plant for higher yield over straight selection. The cross combinations of KS-401 × Azad Krishna showed high SCA effects as well as per se performance in F1 and F2 generations.
