Introgression from Gossypium hirsutum is a driver for population divergence and genetic diversity in Gossypium barbadense

Interspecific introgression from Gossypium hirsutum has reorganized the genomic architecture of Gossypium barbadense. In this study, the genetic basis of population differentiation and the genetic diversity were deciphered and the introgression events and haplotype selection affecting associated fiber quality and environmental adaptation traits were illuminated in Gossypium barbadense. This study provides new insights into the breeding history of Gossypium barbadense and will guard the breeding programs of modern cultivated Gossypium barbadense.
