Genetic analysis of yield and other quantitative traits was done through generation mean analysis. Simple additive-dominance model was found inadequate in all the crosses for most of the characters indicating importance of non-allelic interactions. Both additive and dominance gene effects were significant in most of the cases but magnitude of dominance component was more in general and negative, hence, decreasing the expression of characters. In addition, epistasis was also important in most of the characters in different crosses. Thus, to exploit all the three types of gene actions present in most of the cases, recurrent selection has been suggested. Epistasis was mostly and of duplicate type which will reduce variation in F2 subsequent generations and hinder the pace of progress through selection.
