The article presents the results of the analysis of the formation of the traits "staple length" and "yield" of the fiber of collection samples with naturally colored fiber, in order to involve the best in breeding aimed at creating varieties with naturally colored fiber. According to the results of the analysis, the best samples were selected: - sample 02757 ssp.mexicanum beige fiber, staple fiber length 31.6 mm; - sample 101105 dark brown fiber has an advantage in terms of "fiber output", where M = 36.9 ± 0.84; δ=3.39; V% = 9.17 - accessions 02757 and 101105 should be used in breeding cotton varieties with naturally colored fiber and combining high yield and staple fiber length.
