Correlation and path analysis for seed yield in sesame (Sesamum indicum L.)

Character association was studied to assess the relationship among yield and its components for selection criteria to be followed while developing varieties.Correlation and path analysis of 45 hybrids and 14 parents for the characters, Days to maturity, plant height, number of branches per plant, number of capsules per plant capsule length, number of seeds per capsule, Thousand seed weight, oil content and seed yield per plant. Character association analysis revealed strong positive association of seed yield per plant with number of branches and number of capsules per plant. Path coefficient analysis revealed that number of branches and number of capsules per plant had high positive direct effect on seed yield per plant. Hence number of branches and number of capsules per plant may be good selection criteria for seed yield per plant.
