Correlation and path coefficient analysis in sesame (Sesamum indicum L.)

Correlation and Path coefficient analysis was done on 81 genotypes of sesame (Sesamum indicum L.) for eleven characters. ANOVA revealed highly significant differences among genotypes for traits, except seed weight per capsule. Seed yield per plant had significant positive association with capsules per plant, capsule length, plant height, days to maturity, branches per plant and seeds per capsule. Path coefficient analysis revealed maximum positive direct effect of capsules per plant on seed yield followed by seed weight per capsule and plant height, while negative direct effect on capsule length, oil content and days to maturity was observed. Selection for the traits with positive association and direct effects will be useful for the improvement in yield of sesame through breeding programme.
