Abstract


The genetic analysis for yield and its components was attempted using 4x4 diallel. The diallel analysis showed the importance of both additive as well as non-additive gene action for all the traits studied. Except for ear bearing tillers, SCA variances were higher than GCA variances for all the traits suggesting the predominance of non-additive gene action. In the case of ear bearing tillers, the GCA variance was greater than SCA variance indicating more of additive gene action. Parents with high combining ability have been identified
