Generation mean analysis was carried out to study nature and magnitude of gene effects for yield and its yield component in a cross of sesame (SesamumindicumL.) 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 the cross investigated. Hence, selection should be delayed until virtual homozygosity is attained to achieve the improvement in these traits.
