Study of inheritance of color lint genes in cotton (Gossypuim sp.), by using 2 white lint cultivars, Takfa 2 and Kaset 2, 3 brown lints cultivars were B624, B651 and New Hairy Brown and 1 green lint cultivar. Green as parental for crossing. Used white lint cotton was female parent, brown and green lint cotton were male parent. The F1 hybrid seeds were grown for selfing and the F1 hybrid cross seeds and F2 hybrid seeds were harvested for test about counting number color lint from F2 hybrid cross plants to compare the ratio among white lint cottons with brown lint cottons and white lint cottons with green lint cottons, that followed Mendel's law of segregation. And using statical analyses by Chi-square test. The result showed that the phenotype ratio of F2 hybrid between cotton plants with white lint and green lint was not 1:3 which was not agreeable with Mandel's law of segregation. On the other hand, the phenotype ratio of F2 hybrid cross between cotton plants with white lint and brown lint was 1:3 which was agreeable with Mendel's law of segregation where the dominant gene had completely dominated over the recessive gene.
