Almost all cotton fibers produced in the world are white; however some tetraploid cottons produce naturally colored lint ranging from brown to green which can help to reduce the use of toxic dyes in the textile industry. Fiber color is a genetically inherited feature resulting from the presence of pigments intermingled with cellulose in the cotton fiber. The present study was conducted at the Agricultural Research Station, Dharwad Farm during Kharif, 2018 and 2019 to understand the inheritance pattern of the brown color in color-cotton. The F2 population was considered to study the gene action and to reconfirm the same, the F2:3 populations were also investigated. The variation observed for the color was quite high with different shades of brown lint color in the two populations studied. According to the χ2 test, the F2 and F2:3 populations segregated into colored fiber and white fiber lines which fit well into the expected 1:2:1 ratio, indicating incomplete dominant gene action.
