Özet: Cotton plant (Gossypium spp.) has different natural fiber colors such as brown, green and gray with white. In this study which conducted in Kahramanmaraş conditions with randomized blocks design in 2014, representation rates of the single plants having brown fiber which selected from F9 combinations of them were determined in terms of seed cotton yield, gin turn out, fiber yield and seven fiber properties. As a result of the study, though the genotypic differences were determined insignificant in terms of fiber fineness, were found verry important in terms of other characteristics and the represent ratios of single plants were found minimum 80.6% (fiber uniformity) and maximum 93.8% (fiber strength). While the F9 generations that have brown fiber is located between Giza 45 (Gossypium barbadense L.) and other parents which having white fiber due to their gin out turn, negatively had differentiated from parents which having white fiber in terms of fiber length, strength, maturity and short fiber content. It was determined that all combinations having brown fiber could not compete not only Giza 45 but other parents having white fiber also in terms of gin out turn. Moreover, these combinations could not compete with Giza 45 in terms of fiber length, strength and uniformity ratio also. On the other hand, it was determined that while the Brown 233 hybrid was separated from other hybrids in terms of fiber content, length, strength, uniformity and seed cotton yield, the Brown 235 had separated due to seed cotton yield too.
