Abstract:

Generation mean analysis study in cowpea was undertaken to estimate the gene action operating in the inheritance of yield and its components using six basic generations viz. P1, P2, F1, F2, BC1 and BC2 of two different crosses namely PGCP-63 X Pant Lobia-1 and Pant Lobia-3 x Pant Lobia-1 were studied. For most of the studied traits, additive, dominant, additive x additive, additive x dominance and dominance x dominance were significant. Additive effect significantly contributed for number of pods per plant and 100 seed weight. Dominance effect was significant for the pod length in both the families. Additive x dominance type of interaction contributed significantly for days to flowering, days to pod maturity and seed yield per hectare. Duplicate type of epistasis was observed for days to flowering, and pod length in family1 and also in family 2.The findings suggested that the recurrent selection could be followed in cowpea improvement.
