Combining ability for yield and yield components through diallel analysis in okra [Abelmoschus esculentus (L.) Moench]

Combining ability analysis was carried out for fruit yield and its components in okra in a 8 x 8 full diallel cross. Both general a combining ability (GCA) and specific combining ability (SCA) variances were highly significant for all the characters indicating the importance of both additive and non-additive gene actions. The proportion of variance due to GCA/SCA was found to be less than unity for all the characters except for fruit length indicating predominance of non-additive gene action in determining these traits except fruit length which is determined by additive gene action. The highest gca effect for fruit yield per hectare recorded in Arka Anamika followed by Arka Abhay. | Combining ability for yield and yield components through diallel analysis in okra Abelmoschus esculentus L.
