Generation mean analysis was carried out by in two cross NUK-15-02 × NUK-15-07 and NUK-15-02 × GU-1 of blackgram. The mean is partition in to additive, dominance and epistatis by using six parameter model. Magnitude of dominance gene effect was higher than the additive gene effect for most of traits in both the crosses. Among epistasis, additive × additive gene interaction was found to be significant in cross NUK-15-02 × NUK-15-07 for days to first flower, days to maturity, number of branches per plant, number of seeds per plant, 100 seed weight and seed yield per plant and in cross NUK-15-02 × GU-1 for days to first flower, days to maturity and 100-seed weight. Dominance × dominance component contributed significantly in cross NUK-15-02 × NUK-15-07 for branches per plant and100 seed weight and in cross NUK-15-02 × GU-1 for days to first flower, days to maturity, plant height, branches per plant and 100 seed weight. Hence selection should be carried out in later generation and it would be desirable to follow bi-parental mating followed by population improvement approach that take care of both additive and non-additive gene actions are more promising for the improvement of various characters studied.
