Abstract

A total 500 accessions were evaluated to determine the associationship among the traits along with their direct and indirect effects on seed yield. Observations were recorded on twelve traits viz., days to flower initiation, days to fifty percent flowering, days to maturity, plant height (cm), number of primary branches per plant, number of secondary branches per plant, number of capsules per plant, number of seeds per capsule, capsule length (cm), 1000 seed weight (g), seed yield per plant (g) and oil content (%). The experiment results revealed that Seed yield per plant exhibited significant positive correlation with number of seeds per capsule followed by capsule length and number of capsules per plant. Path analysis showed that number of seeds per capsule had the high positive direct effect on seed yield followed by number of capsules per plant. On the basis of correlation and path analysis number of seeds per capsule, number capsules per plant and capsule length were observed as t

Keywords

Sesame, correlation, path analysis.

Conclusion

Correlation coefficients and path analysis were computed on different traits viz.,days to flower initiation, days to fifty percent flowering, days to maturity, plant height (cm), number of primary branches per plant, number of secondary branches per plant, number of capsules per plant, number of seeds per capsule, capsule length (cm), 1000 seed weight (g), seed yield per plant (g), oil content (%). Results revealed that, on the basis of correlation and path analysis number of seeds per capsule, number capsules per plant and capsule length were determined the most critical traits. Selection of these traits can be helpful for a breeder to improve the crop yield.
