A 6×6 diallel analysis of containing ability for 5 quality attributes, e.g. protein, tryptophan, methionine, fat and ash content suggested the importance of both additive and nonadditive gene actions in F1 and F2 generations for the control of these traits. The parental performance was a good indication of their gca. The cultivar 5742-1A was a good general combiner for protein, tryptophan and ash content, while CSV 4 and CSV 6 were good general combiners for methionine and fat content.
