Abstract
The improvement of cotton fibre quality has become more important because of changes in spinning technology. Stable quantitative trait loci (QTLs) for fibre quality will enable molecular marker-assisted selection to improve fibre quality of future cotton cultivars. A simple sequence repeat (SSR) genetic linkage map consisting of 156 loci covering 1,024.4 cM was constructed using a series of recombinant inbred lines (RIL) developed from an F2 population of an Upland cotton (Gossypium hirsutum L.) cross 7235 × TM-1. Phenotypic data were collected at Nanjing and Guanyun County in 2002 and 2003 for 5 fibre quality and 6 yield traits. We found 25 major QTLs (LOD ≥3.0) and 28 putative QTLs (2.0 < LOD < 3.0) for fibre quality and yield components in two or four environments independently. Among the 25 QTLs with LOD ≥3, we found 4 QTLs with large effects on fibre quality and 7 QTLs with large effects on yield components. The most important chromosome D8 in the present study was densely populated with markers and QTLs, in which 36 SSR loci within a chromosomal region of 72.7 cM and 9 QTLs for 8 traits were detected
