Abstract:

Generation mean analysis study in cowpea was undertaken to estimate the gene action operating in the inheritance of yield and its components. Six basic generations viz., P1, P2, F1, F2, BC1 and BC2 of five crosses, namely Pant lobia-1 x BRDCP-11 (cross I), Pant lobia-2 x GC-3 (cross II), Waghi local x W-203-1 (cross III), KM-5 x GC-3 (cross IV) and GC-3 x CDP-107 (cross V) were studied. Scaling test was applied to test the adequacy of additive-dominance model for the traits under investigation. The dominance component was higher in magnitude than additive component for all the characters studied along with duplicate type of epistasis in most of the cases. Both, additive and non-additive gene action contributes significantly in the inheritance of various quantitative characters in cowpea
