The present investigation was conducted with twenty-one genotypes following RBD with three replications during kharif
, 2017. Data on morpho-physiological and yield traits were recorded on six randomly selected plants. The analysis of variance revealed significant differences among the genotypes for each character, indicating the presence of considerable variability among the genotypes for the characters studied. Correlation studies indicated that harvest index, productive capsules per plant, number of seeds per capsule, number of branches per plant, productive branches per plant, biological yield, 1000 seed weight and plant height showed significant positive association with seed yield per plant as well as among themselves at phenotypic and genotypic level. Hence, selection for any one of these characters would bring in simultaneous improvement of other character and ultimately seed yield. The traits viz.,
plant height, number of branches per plant, days to maturity, number of seeds per capsule, biological yield and harvest index had positive direct effect on seed yield. Path analysis revealed that high positive direct effect was exhibited by number of branches per plant, biological yield and harvest index with positive and significant correlation for seed yield; hence, selection based on these characters would be more effective for yield improvement in sesame.
