Creation of goods with high fiber quality from the selection of varieties belonging to G.Hirsutum L. species

Abstract

One of the important problems in cotton breeding is the creation of high-yielding, fast-maturing varieties with high fiber yield and quality and their wide use in production. In the world, the cotton plant occupies a key place in the world textile industry. The purpose of the study was to determine the effectiveness of these methods in creating genetically enriched selection materials based on a comparative study of the heredity, variability and formation of economic traits in cotton hybrids created by different methods of convergent hybridization. The analysis of the homogeneity index showed that the character index of convergent families based on the principle of transgressive recombination ranged from 86.7 % (O-329/30) to 88.3% (O-32/35). In families O-85/90 and O-325/26, it was 87.4% and 87.95%, respectively.
