Present study was conducted to estimate combining ability and type of gene action for fibre quality parameters in desi cotton genotypes. Ten genotypes (six lines and four testers) and twenty-four crosses were evaluated in randomized block design with three replications during kharif 2012-13. The characters viz., ginning outturn, 2.5% span length, fibre fineness, fibre strength, uniformity ratio and short fibre index were included under the study. Predominance of non-additive gene action was obtained for almost all the characters under study. The mean squares due to males were non-significant for all characters studied. The female lines exhibited significant differences for fibre strength only. Mean square due to crosses was significant for all the six characters indicating the importance of the studied traits. The estimates of GCA effects revealed that among lines, PA-08 was highest performing line for more number of characters followed by PA-720 and PA-255 while, among testers GAM-162 was the highest performing for more number of characters. These lines and testers being good general combiners can be used as donor parent for desirable genes regarding the mentioned traits.

Key words: Kharif, GCA, Cotton, Fibre.
