Abstract: Generation mean analysis study was carried out to estimate the gene action governing inheritance of yield and its components in blackgram using six parameter model. Six generations of a cross NUK-15-02 × NUK-15-09 was studied. Simple scaling test as well as joint scaling test were carried out to check the adequacy of additive-dominance model. Additive gene effect had lower magnitude than dominance gene effect in most of the characters. Additive × additive type of epistatis was found significance for days to first flower, plant height and branches per plant. Dominance × dominance gene interaction was registered significant by days to first flower, days to maturity and plant height. Hereby for the improvement of various characters studied in this cross, followed population improvement approach which takes in to account both additive and non-additive gene action.
