Favorable pleiotropic loci for fiber yield and quality in upland cotton (Gossypium hirsutum)

Abstract Upland cotton (Gossypium hirsutum L.) is an important economic crop for renewable textile fibers. However, the simultaneous improvement of yield and fiber quality in cotton is difficult as the linkage drag. Compared with breaking the linkage drag, identification of the favorable pleiotropic...
