Abstract:
In the present investigation, fifty desi cotton (Gossypium arboreum L.) genotypes including six checks viz., AKA 7, AKA 8, JLA 794, JLA 505, PA 255 and PA 402 were studied to observe genetic variability, heritability and genetic advance for thirteen yield contributing and fiber quality characters. The analysis of variance revealed that the sufficient variability was present in the material for all the characters. The phenotypic coefficient of variation was higher than genotypic coefficient of variation. High estimates of GCV and PCV were observed for seed cotton yield per plant and moderate GCV and PCV for number of bolls per plant, plant height, lint index, seed index and boll weight. High heritability coupled with high genetic advance over mean was observed for the characters seed cotton yield per plant, number of bolls per plant, number of sympodia per plant, plant height and lint index indicating the presence of additive gene action in the inheritance of these traits. Whereas high heritability with moderate genetic advance was observed for fibre strength, fibre fineness, upper half mean length, seed index and boll weight.
