Abstract

Generation mean analysis was carried out to study nature and magnitude of gene effects for yield and its yield component in the cross of sesame (Sesamum indicum L.) The parents with their F1, F2, B1 and B2 were evaluated in replicated trail for ten quantitative traits. The analysis showed that scales A,B and C are highly significant for seed yield/plant and all the ten yield components, indicating the predominance of non-allelic interactions or epistasis of Additive x Additive (i) and Dominance x Dominance (l) for almost all the ten characters in the cross. Predominance of non-additive (dominance) gene action was prevailed in the expression of seed yield/ plant, its components with duplicate type of epistasis in both the crosses investigated. Hence, selection should be delayed until virtual homozygosity is attained to achieve the improvement in these traits.
