Abstract: A wide range of average performance and genetic variability was estimated for F1 crosses of nine commercial varieties of cotton viz., CIM443, MNH147, FH-682, N. Krishma, SLS-1, CIM-446, CIM448, FVH-53 and MNH552 for bolls and seed cotton yield per plant, boll weight, staple length, ginning out turn (%) and virus infestation (%). The highest genotypic variability was recorded for virus infestation (94.61%) followed by bolls per plant (29.84%). The highest estimates of heritability associated with highest genetic advance for bolls per plant (97.8 and 60.78), virus infestation % (95.0 and 189.9) and boll weight (97.39 and 10.99) suggested selection for improvement of these traits due to presence of sufficient genotypic variability. However, low estimates of these parameters for staple length showed slow progress through selection.
