Abstract:
Correlation coefficient analysis and path analysis were carried out to determine the effects of fourteen traits as components of seed yield in thirty white seeded sesame genotypes. The genotypes were evaluated in Randomised Block Design with three replications during summer season 2019-2020 at the ORARS, Kayamkulam. Correlation among the traits revealed that seed yield per plant was positively associated with number of capsules per plant, dry matter production, plant height, number of capsules per leaf axil, leaf area, primary branches per plant, number of seeds per capsule, capsule length and days to 50 per cent flowering suggesting that selection made on the basis of these characters will assist in enhancing the seed yield. The path coefficient analysis of different characters contributing towards seed yield per plant showed highly positive direct effect by characters viz., number of capsules per plant, number of seeds per capsule, number of capsules per leaf axil and plant height. Indirect positive effect was showed by number of capsules per plant via plant height, primary branches per plant, number of capsules per leaf axil, capsule length, leaf area and dry matter production.
