Combining ability studies for yield and quality characters in blackgram under different environments

Additive and non-additive gene effects were found to be important in the expression of seed yield and quality traits, i.e., protein content, water absorption and dal recovery when studies conducted at three locations through a 10 X 10 diallel cross of blackgram. Interaction mean squares of gca and sca with environments were significant, indicating their inconsistency over environments. On the basis of per se performance and gca effects, the parents GU 1 and RBU 38 emerged as good general combiners for seed yield per plant, protein content, water (absorption g/g seeds) and dal recovery.
