Abstract:
Any crop's genetic diversity is a requirement for choosing genotypes that are superior to the cultivars already in use. Knowing the yield's heritability, variability and contributory factors aids in choosing the best strategy for a breeding program aimed at creating superior varieties. As a result, the current experiment was carried out to evaluate the degree of variability in cotton for factors related to yield and fiber quality. Analysis of variance in the current investigation demonstrated the presence of significant genetic variability in the experimental materials, indicating significant variations for every characteristic among genotypes. The number of bolls per plant, plant height, lint index, seed index, and boll weight had moderate GCV and PCV whereas the seed cotton yield per plant had high GCV and PCV. The characters seed cotton yield per plant, number of bolls per plant, number of sympodia per plant, plant height and lint index showed high heritability estimates along with high genetic advance as percent mean, indicating the presence of additive gene action and suggesting that phenotypic selection may be more effective and efficient for desired genetic improvement.
