Studies on combining ability analysis in okra

The present experiment was conducted with 21 F₁s and F₂s developed through diallel hybridization technique excluding reciprocals along with seven parents in RBD with three replications. Varieties KS387, KS-404 and Pusa Sawani showed good general combining ability for yield appear to be worthy of exploitation in future hybrid development. It is suggested that population involving these lines may be developed through multiple crossing isolating high yielding varieties. The specific combining ability effects indicated that choice of parents could be based on 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 per plant for higher yield over straight selection. The cross combinations of KS-401 x Pusa Sawani showed high specific combining ability effects as well as per se performance in F₁ and F₂ generations.
