This review provides a detailed discussion on the impact of comparative genomics research in Gossypium species on cotton improvement. Through high-quality genome assemblies and whole-genome comparative analyses, the study reveals the evolutionary history, domestication process, and the genetic basis of key traits, particularly improvements in fiber quality, yield, and stress tolerance. Genomic tools such as genome-wide association studies (GWAS) and quantitative trait locus (QTL) mapping have identified key genetic loci associated with important traits, promoting the application of marker-assisted selection and genomic selection. Moreover, advancements in gene editing technologies like CRISPR/Cas9 offer great potential for precision breeding in cotton, aiming to develop varieties with enhanced fiber quality, disease resistance, and environmental adaptability. In the future, integrating multi-omics data will provide a more comprehensive understanding of cotton biology and its response to environmental stresses, contributing to further advancements in global cotton yield and quality.
