Abstract:

Combining ability analysis was carried out for earliness, fruit yield and its related traits in okra in a 6 × 6 full diallel fashion. Both general combining ability (GCA) and specific combining ability (SCA) variances are highly significant for all the characters indicating the importance of additive and non-additive gene actions. The highest significant negative GCA effect for earliness were recorded by the parents Arka Anamika, Parbhani kranti and for fruit yield per plant the best general combiner were found to be Parbhani kranti. The highest significant positive SCA was in the cross combination Arka Anamika × Parbkani Kranti for fruit yield per plant. The cross combination Arka Anamika × Parbkani Kranti recorded earliest flowering. Highest heterosis percentage for fruit yield per plant was observed in the cross combinations Parbkani Kranti × EC-305626 and Arka Anamika × Parbkani Kranti and for earliness it was observed in Arka Anamika × EC-305626.
