Heterosis And Combining Ability For Yield Components And Fiber Quality Parameters In A Half Diallel Cotton (G. Hirsutum L.) Population^1, Hüseyi̇n Başal, İsmai̇l Turgut
Turkish Journal of Agriculture and Forestry
Combining ability and heterosis were determined in a population obtained from the half diallel crossing of 6 different cotton genotypes for yield components and fiber quality parameters. For breeding purposes, to improve the investigated characters some suitable parents were selected for different characters: DPL 5690 for number of bolls per plant, Acala SJ-5 for boll weight and fiber length; Nazilli-84 and Carmen for seed cotton yield and lint percentage; Tamcot CAMD-E for earliness and fiber fineness; and PD 6168 for fiber strength. When the crosses were evaluated for the investigated characters Tamcot CAMD-E x Carmen, Nazilli-84 x PD 6168, DPL …

The purpose of this study was to determine estimates of the general combining ability of parents and the specific combining ability of hybrids needed to develop high yielding cotton cultivars. Five cotton lines (Sure Grow 125, Sure Grow 404, Sure Grow 501, Sure Grow 1001 and Çukurova 1518) and 7 testers (PAUM 400, PAUM 401, PAUM 402, PAUM 403, PAUM 404, PAUM 405 and PAUM 406) were crossed in a line x tester mating system at Çukurova University, Cotton Research and Application Center, Adana, Turkey, in 2000. Twelve genotypes and 35 F_1 hybrids were sown in a randomized complete block …
