Abstract

This article presents an analysis of the variability of fiber yield of F2 hybrids obtained with the participation of US and Mexican cotton samples. In this case, in F2 hybrids, the highest indicators (42.2%) were obtained when S-4727 was taken as the mother, and in other combinations, when varieties were taken as the mother, the hybrids had positive indicators. In the hybrid combination F2 (Chimboy-5018 x 011656), the fiber yield indicator was 39.9%, and when the Chimbay-5018 variety participated as the mother, the fiber yield indicator was 35.5%, that is, in this case, the indicator was 4.4% higher than the Chimbay-5018 variety, and 2.8% higher than the sample No. 011656, which participated as the father.
