Abstract:

The study was conducted during kharif, 2018 at experimental block of Agricultural College, Bheemarayanagudi to evaluate twenty upland cotton genotypes for 15 characters in a Randomized Complete Block Design. Analysis of variance revealed significant differences for all traits revealing a high degree of variability among the genotypes. Number of monopodia per plant, sympodial length at fifty per cent of plant height and number of bolls per plant showed high GCV and PCV. While upper half mean length, fibre strength, ginning outturn and micronaire showed comparatively low GCV and PCV. High heritability coupled with high genetic advance as per cent of mean were observed for plant height, number of sympodia per plant, sympodial length at fifty per cent plant height, inter-nodal length, number of bolls per plant, boll weight and lint index, indicating the existence of additive gene action hence selection on phenotypic basis might be productive. Variability studies help to determine the selection criteria for the improvement of yield and quality traits.
