The experimental material Claudia, Candia, Şahin 2000, BA 308, Naz 07 and Fantom (Gossypium hirsutum L.) were used as a female parents and Giza 45 and Avesto (Gossypium barbadense L.) used as a male parents. The selected cotton genotypes were crossed by line tester method. An experiment was carried out in randomized complete block design with four replications to assess hereditary and heterotic effects on yield components and fiber quality traits. The research was carried outat Cotton Research Station Nazilli during the year 2011. Positive heterosis percentage was obtained from all hybrids for fiber length and fiber strength. Standard heterosis values were positive and significant for fiber length, fiber strength and micronaire.The performance of all combinations for yield and fiber quality traits at F1 generations showed that Claudia x Giza 45, Candia x Giza 45, Şahin 2000 x Giza 45, BA 308 x Avesto, Naz 07 x Giza 45 and Fantom x Avesto hybrid populations would be used for improve cotton lines having enhanced for fiber length with acceptable yield potentials.
