The quality of the fiber in the lines of medium staple cotton in 2018-2020 was assessed. in Tashkent, Fergana and Kashkadarya regions of the Republic of Uzbekistan. 10 lines of different genetic origin were tested. The influence of the genotype and the environment on the manifestation of the qualitative parameters of the fiber (length, specific breaking load, micronaire) was studied. As a result of three years of experiments, it was found that the length of the fiber is equally affected by both the genotype and the environment (up to 40%). The genotype significantly affects the specific breaking load of the fiber (68%). The variability of the micronaire fiber was more dependent on the genotype from 35 to 48.4%, the contribution of the environment was from 2.6 to 16%.
Key words: Gossypium hirsutum / genotype / environment / fiber quality / selection
