Abstract:
Genetic variation, Principle component analysis and Path analysis were analysed in sixty cotton (Gossypium hirsutum L.) genotypes and Randomized Complete Block Design was followed with three replications. A wide spread variation was observed among all the investigated attributes. Principle component analysis was worked out to identify the diverse genotypes. Bolls per plant, sympodia per plant and boll weight showed noteworthy positively association with seed cotton yields. Path analysis exposed uppermost positive direct consequence of number of bolls per plant on total yield whereas sympodia per plant and boll weight had maximum indirect positive effect through number of bolls on seed yield. The correlation analysis and path coefficient analysis and Principle component analysis together suggested that these attributes and genotypes should be given prime emphasis in effective selection to get better cotton seed yield.
