The nature of genetic architecture for four yield components were studied in six crosses of sesamum during Kharif, 1978. The results revealed that the component of additive and dominance had played an important role in the expression of these characters. However, among epistatis, additive X additive component was observed important for the characters under study. The additive gene action was found to be predominant for plant height.
