Generation mean analysis was employed in two crosses viz., MDU 1 x Mash 114 and MDU 1 x Mash 1008 of balckgram to partition the mean into various components viz., additive, dominance and epistasis. Traits viz., number of clusters per plant, pod length, and number of seeds per pod were controlled by additive gene action in the cross MDU 1 x Mash 114. The additive as well as additive x additive type of gene action were in control of seed yield per plant, MYMV disease scores and most of yield components in the cross MDU 1 x Mash 114. Hence selection at later generation is effective to improve these traits. In case of MDU 1 x Mash 1008 also, most of the traits except seed yield per plant, number branches per plant and number of cluster per plant had epistatsic model. Hence selection needs to be postponed to later generation. Hence based on gene action, the cross MDU 1 x Mash 114 may be utilized to evolve high yielding plants with MYMV disease resistant genotypes.
