Investigation of yields, yields component and lint quality traits inheritence in some cotton breeds (Gossypium hirsutum L.x Gossypium barbadense L.)

The study was carried out on the Nazilli Cotton Research Station fields during 2011 and 2012 cotton growing seasons. 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 in 2011. Hybrid combinations were compared in terms of yield, yield components and fiber quality parameters at F1 generations. In combination, fiber quality properties, yield and hereditary and heterotic effects on yield components were examined.Additive gene effects were highly significant for ginning out turn and plant height. Non-additive gene effects were highly significant for yields, number of bolls, sympodia per plant, fiber strenght, micronaire, short fiber index, monopodia per plant, 100 seed weight, single boll weight, fiber lenght and fiber uniformity index.Positif heterosis percentage was obtained in all hybrids for fiber lenght and fiber strenght and in eight hybrids for micronaire. Standart heterosis values was positif and significant for fiber lenght, fiber strenght 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 partial bulk selection in order to improve cotton lines having enhanced for fiber length with acceptable yield potentials.
