Correlation and path coefficient analysis of yield contributing and fiber quality traits in Desi cotton (Gossypium arboretum L.)

In the present investigation, correlation and path coefficient analysis was carried out for fifteen different yield contributing and fiber quality traits in desi cotton (G. arboreum L.) using 39 genetically diverse desi cotton genotypes along with three checks. Correlation studies revealed significant and positive genotypic and phenotypic correlation of number of bolls per plant, number of sympodia per plant, lint index, boll weight, plant height, ginning percent, seed index and harvest index with seed cotton yield per plant. The path analysis studies revealed that, the traits viz., number of bolls per plant, boll weight, plant height, number of sympodia per plant, harvest index, days to 50 percent flowering, lint index, uniformity ratio and micronnaire exerted direct positive effect on seed cotton yield. Therefore, these characters should be given due emphasis for making selection for high yielding genotypes in desi cotton.
