Abstract: This paper deals with the results of conducted research on the issues of the inheritance and variability of boll weight in F1-F2 plants of fine-fiber local cotton varieties. According to the experiments, we have made that generation hybrids in F1, the trait of boll weight were inherited basically positive superdominance. Additionally, the determination of the general combining ability of fine-fiber cotton varieties of morpho-agronomic traits, and genetic-selection were further conducted the possibility of using Duru Gavkhar and Bukhara-7 varieties as a valuable primary source of cotton weight of boll. Furthermore, selection work in the population of the family O-449, depended on the basis of a combination of F2 Surkhan-9 x Termez-32 hybrids. Moreover, a new cotton variety "Marvarid" was created.
Key words: fine-fiber cotton varieties, hybrids, heterosis, combining ability, inheritance, variability, boll weight.
