Abstract

Generation mean analysis in yard long bean was undertaken to estimate the gene action operating in the inheritance of quality characters pod protein (%) and  keeping quality (% weight loss). Six basic generations viz., P1, P2, F1, F2, BC1 and BC2 of two crosses, namely [VS 50 x VS 34]Kakkamoola Local x Githika (cross 1) and [VS 50 x VS 26] Kakkamoola Local x Vellayani Jyothika (cross 2) were studied. Significance of scaling test revealed the presence of epistasis for characters under investigation. The predominance of dominance component for the characters under study   indicates the improvement of the traits through heterosis breeding
