Abstract: The article carry out information about combining ability of the parent varieties of fine-fiber cotton varieties. Information about combining ability of parents and crossings is crucial in breeding efforts. Genetic variety is crucial to the effectiveness of yield improvement efforts because it helps to broaden gene pools in any given cotton. The presence of statistical differences in total productivity trait indicators in some reciprocal combinations of F1 generation of fine-fiber cotton varieties suggests that cytoplasmic genes as well as nuclear genes are involved in the genetic control of these traits. In combinations F1 Surkhan-9 x Termez-32, F1 Surkhan-9 x Surkhan-10, F1 Surkhan-10 x Termez-32 and F1 Surkhan-10 x Duru Gavkhar, the positive heterosis effect on total productivity was 122.7-157.2%. These hybrid combinations can be use as a valuable resource for heterosis selections. It was noted that the nonadditive effect of genes on plant productivity in F1 plants of varieties was strong.
