Combining ability analysis for yield and its components in groundnut (Arachis hypogaea L.)

Combining ability was studied among 24 crosses involving eight lines and three testers. The general and specific combining ability variances were highly significant for all the characters studied. The parent VRI Gn 6 proved to be a good general combiner for yield and yield components. Three crosses viz., VRI Gn 6 x GAUG 10, VRI Gn 6 x VRI 2 and VRI 4 x UG 9 exhibited desirable sca effects and also recorded higher per se performance. Most of the crosses involved parents with high x low gca effects which showed the involvement of non-additive gene action in controlling these characters.
