Abstract: A field experiment was conducted during the 2013 in kharif season with 40 genotypes of sesame representing different geographical regions of India to study the correlation and path analysis for 14 characters. The estimate of correlation coefficient revealed that the genotypic correlations were higher than their corresponding phenotypic correlation for all the characters. It was observed that days to maturity, number of branches per plant, number of capsules per plant, number of seeds per capsule, 1000- seed weight and protein content showed significant positive association with seed yield per plant at genotypic as well as phenotypic levels. Plant height showed positively and significantly correlated with number of branches of per plant, number of capsules per plant, days to maturity, internode length and number of leaves. The results pointed out that more emphasis should be given on days to maturity, plant height, number of branches per plant, number of capsules per plant, number of seeds per capsule, protein content and1000- seed weight to improve grain yield. The results of path analysis showed that the characters viz., days to maturity, capsule length, number of branches per plant, protein content, number of branches per plant, number of capsules per plant, number of seed per capsule, 1000-seed Weight and leaf length had positive direct effect with seed yield, while plant height, internode length and number of leaves per plant and days to 50% flowering were having negative direct effect. Based on correlation and path analysis, it is suggested that emphasis should be given on number of branches per plant, number of capsules per plant, number of seed per capsule, 1000-seed weight for selecting the elite genotypes for further breeding program.
