Cotton (Gossypium hirsutum L.) is one of the most important plants worldwide because of its fiber that is used as raw material for the textile industry. Since the dyes used in dyeing process negatively affect the environment, many people prefer to use natural colored cotton products. The objective of this study was to establish the inter-relationship and direct and indirect effect of various quality traits on seed cotton yield in colored cotton genotypes. The F-3 and F-4 generations of the cross between Carmen (white) and Devetuyu-176 (brown fiber) were used for selection process in terms of seed cotton yield per plant and fiber color. The measured quality traits in the selected genotypes from F-3 and F-4 generations were micronaire, fiber strength, fiber length, uniformity ratio, short fiber index, fiber elongation. Phenotypic correlation and path coefficients were calculated separately for each generation. As results of the correlation analysis, seed cotton yield was not negatively associated with fiber quality properties. It may be concluded that the selection for seed cotton yield and fiber color should be applied in early generations and fiber quality properties of the selected promising colored cotton genotypes can be determined in further generations of Carmen x Devetuyu-176.
