Abstract

By analyzing recent advances in sequencing technology, marker-assisted selection (MAS), and gene editing, this study highlights the potential for integrating genomics tools into modern cotton breeding programs. The results show that key fiber-related gene families and quantitative trait loci (QTLS) regulating fiber strength, length and fineness have been identified. The relevant case studies demonstrate the practical application of genomics in breeding programs, which have achieved significant improvements in fiber quality through marker-assisted selection. The study concludes that the use of evolutionary genomics in cotton breeding will accelerate the development of high-quality fiber traits, thereby enhancing the productivity and competitiveness of the cotton industry. The purpose of this study was to investigate the evolutionary history, genome structure and genetic diversity of cotton plants, and to analyze how these factors affect the improvement of cotton fiber characters.
