Abstract:
To facilitate marker-assisted selection, there is an urgent need to construct genetic map and identify QTL for agronomy traits in upland cotton (Gossypium hirsutum L.). Three upland cotton RIL populations (T586 × Yumian 1), (CCRI35 × Yumian 1) and (7235 × Yumian 1) were used to construct genetic map and identify QTL controlling agronomy traits. For population (T586 × Yumian 1), the genetic map contained 1609 loci and covered 4270.2 cM, and the identified QTL included 35 for fiber quality traits, 131 for seed traits, 48 for photosynthetic traits and 12 for lint percentage. For population (CCRI35 × Yumian 1), the genetic map contained 1069 loci and covered 3732.4 cM, the identified QTL included 48 for fiber quality traits and 19 for yield traits. For population (7235 × Yumian 1), the genetic map contained 1363 loci and covered 2887.7 cM, and the identified QTL included 43 for fiber quality traits and 11 for lint percentage.
