Cause and effect relationship between seed yield and its components in sesame

摘要

Genotypic correlation and path co-efficient analysis were studied in 80 F_1 hybrids derived from 20 (lines) X 4 (testers) mating design for 10 quantitative traits. Significant correlation with seed yield was exerted by number of capsules, plant height, number of branches, test weight, days to maturity, days to 50 per cent flowering and oil content. Number of capsules had the highest positive direct effect on seed yield. The indirect effect of number of branches, plant height, days to maturity, days to per cent flowering and test weight on seed yield via number of capsules was maximum and positive.
