“…In the data of F. Toreev et al [8] based on the analysis of fiber quality indicators of F5 simple and complex hybrids, T-150 and T-195 lines from F 5 simple hybrids and T-212 and T-215 lines from complex hybrids, fibers of F8 simple and complex hybrids based on the analysis of quality indicators, it was determined that the T-3 and T-31 lines from F8 simple hybrids and the T-46 and T-50 lines from complex hybrids meet the requirements of world standards of fiber quality compared to other simple and complex hybrids and model types. K. Khudarganov; M.Rakhmonkulov; In the scientific works of M.Umedova and others [6,7,9], valuable economic traits of cotton, disease and pest tolerance, fiber quality indicators were highlighted, and it was stated that valuable economic traits were superior to the model variety in new lines of cotton.…”

Among the strains derived from simple hybrids studied in the experiments, T-3 T-9, T-18 and strains T-43, T-53, T-57 and 60 from strains derived from complex hybrids were resistant to gommosis and wilt diseases. As a result of several years of research, it was found that the ridges obtained from complex hybrids were less affected by gommosis and wilt diseases than the ridges obtained as a result of simple hybridization. It was found that wilt disease was 3-4 times more resistant in the ridges created as a result of simple and complex hybridization compared to the model seed. Lines T-155, T-158, T-163, T-167, T-188 and T-208 from simple hybrids of cotton and lines T-212, T-215, T-220 and T-222 from complex hybrids are other It was determined that the quality of the fiber meets the requirements of the world standards in relation to the ridges and pattern type. In the studied samples, the families of ridges that do not have positive quality indicators such as fiber micronaire, yarn elasticity coefficient, fiber length, relative tensile strength and fiber uniformity are discarded, and experiments are carried out in the following years in order to incorporate new ridges that meet the requirements of the world standard with other economically valuable characteristics detached to continue.
