Identification of Candidate Genes for Lint Percentage and Fiber Quality Through QTL Mapping and Transcriptome Analysis in an Allotetraploid Interspecific Cotton CSSLs Population.

Upland cotton () has long been an important fiber crop, but the narrow genetic diversity of modern limits the potential for simultaneous improvement of yield and fiber quality. It is an effective approach to broaden the genetic base of through introgression of novel alleles from with excellent fiber quality. In the present study, an interspecific chromosome segment substitution lines (CSSLs) population was established using cultivar Pima S-7 as the donor parent and cultivar CCRI35 as the recipient parent.
