Abstract
The purpose of the present investigation was to examine the relationships between seed yield and yield-attributing characters in sesame (Sesamum indicum L.) as well as evaluating their direct and indirect effects. Results indicated that number of capsules per plant (0.806) and 1000-seed weight (0.657) showed positive correlation with seed yield per plant . Path coefficient analysis indicated that number of capsules per plant (0.806) and 1000 seed weight (0.111) exhibited positive direct effect on seed yield. Positive indirect effect was observed through number of branches per plant via number of capsules per plant (0.657). Number of capsules per plant exhibited positive indirect effect via 1000 seed weight (0.111). Since, it showed strong correlation and direct effect on seed yield per plant, selecting for this trait may leads to improvement of seed yield per plant. Present study revealed that the traits viz., number of capsules per plant and 1000 seed weight association was highly desirable as the improvement in any of the yield components results into overall increase in seed yield. Selection among genotypes based on this analyses can be made for further improvement in seed yield per plant and its contributing characters.
