Abstract: A seven parent diallel including reciprocals were made. The analysis of variance for combining ability revealed the importance of both additive and non-additive gene action in the inheritance of all the 11 traits studied. Reciprocal differences in the estimates of combining ability variances were recorded for all the 11 traits investigated. The parents were identified as good general combiners for most of the characters of interest. The hybrid namely, Varsha Uphar x Thunder portrayed high per se performance coupled with high sca effects for majority of the traits, also evinced high standard heterosis for fruit yield per plant. The standard heterosis was recorded upto the tune of 79.16 per cent by the hybrid Varsha Uphar x Pusa-7 for the trait fruit yield per plant. In the presence of both additive and non-additive gene action coupled with reciprocal differences, reciprocal recurrent selection may be resorted for population improvement.
