Abstract:
In the present investigation, 39 desi (Gossypium arboreum L.) genotypes along with three checks viz., AKA-7, PA-08 and JLA-794 were studied to observe genetic variability, heritability and genetic advance for fifteen yield contributing and fiber quality characters. Analysis of variance showed significant differences for all the characters among genotypes indicating the presence of wide range of genetic variability in the experimental materials. The high GCV and PCV were observed for number of boll per plant, seed cotton yield per plant, number of sympodia per plant, lint index and plant height. High heritability estimates coupled with high expected genetic advance were observed for the characters number of boll per plant, seed cotton yield per plant, number of sympodia per plant, lint index, plant height and micronaire. It indicates the presence of additive gene action and phenotypic selection may be more fruitful and effective for desired genetic improvement.
