Path co-efficient analysis was carried out in parents, F1s and F2s in rainfed sesame during kharif 1997. The parents viz., S.I. 75, S.I. 3012, S.I. 320, S.I. 5354, YLM 17, P.S. 201, Vinayak and Krishna were crossed in diallel fashion with out reciprocals and the resultant F1s and F2s were studied. The negative direct effect of days to maturity on seed yield in F2s is found advantageous for their earliness. The negative effect of plant height in F1s and F2s on seed yield also desirable to get dwarf plant types to avoid lodging. The positive direct effect of capsule number, 1000 seed weight and seed number/capsule on seed yield in F1s and F2s is useful in developing sesame ideotypes.
