Association and Path Studies for Seed Cotton Yield and Lint Quality Characters in Cotton (Gossypium hirsutum L.)

摘要

Twenty nine upland cotton (G. hirsutum L.) genotypes were studied to work out correlation and path coefficients for sixteen characters. The association analysis revealed that due to significant and positive association of seed cotton yield~(-1) with the traits viz., plant height, number of sympodia as well as number of monopodia plant~(-1), seed weight boll~(-1), lint index, seed index and boll weight, selection would be worthwhile for these traits. Selection for lint weight boll~(-1) can also be effective as it exhibited a positive association with lint index and boll weight, which were positively associated with seed cotton yield plant~(-1). The path analysis indicates that direct selection can be preferred for days to 50 per cent flowering, plantheight and number of sympodia plant~(-1).
