Two tetraploid species, Gossypium hirsutum L. and G. barbadense L., dominate the world's cotton production. To better understand the genetic basis of cotton fibre traits for the improvement of fibre quality, a genetic linkage map of tetraploid cotton was constructed using sequence-related amplified polymorphisms (SRAPs), simple sequence repeats (SSRs)and random amplified polymorphic DNAs (RAPDs). A total of 238 SRAP primer combinations, 368 SSR primer pairs and 600 RAPD primers were used to screen polymorphisms between G. hirsutum cv. Handan208 and G. barbadense cv. Pima90 which revealed 749 polymorphic loci in total (205 SSRs, 107 RAPDs and 437 SRAPs). Sixty-nine F2 progeny from the interspecific cross of 'Handan208' 'Pima90' were genotyped with the 749 polymorphic markers. A total of 566 loci were assembled into 41 linkage groups with at least three loci in each group. Twenty-eight linkage groups were assigned to corresponding chromosomes by SSR markers with known chromosome locations. The map covered 5141.8 cM with a mean interlocus space of 9.08 cM. A 2 test for significance of deviations from the expected ratio (1 : 2 : 1 or 3 : 1)identified 135 loci (18.012aLin, Z.12aHe, D.12aZhang, X.12aNie, Y.12aGuo, X.12aFeng, C.12aStewart, J.
