Correlation and path analysis studies of yield and fibre quality traits in cotton (Gossypium hirsutum L.)

Correlation and path coefficient analysis was performed for fifteen quantitative traits of yield and fibre quality for ninety six diverse genotypes. The association analysis revealed significant positive correlation for seed cotton yield per plant with number of monopodia, number of bolls per plant, boll weight and lint index at phenotypic level. The path analysis indicated that boll weight and number of bolls per plant had highest direct effect on seed cotton yield per plant, whereas traits like plant height, UHML, fibre strength and lint index had direct negative effect on yield revealing that due weightage should be given in selection process with more number of bolls per plant and more boll weight and can be considered as principal yield determining components.
