The role of interspecific introgression in the adaptation of Gossypium species is crucial. Gossypium species exhibit rich diversity and wide geographic distribution, with adaptability being key to their survival and development. Interspecific introgression, the process of gene flow between different species, has played a significant role in the adaptation and evolution of Gossypium species. This study reviews the applications and adaptive advantages of interspecific introgression in Gossypium species, including enhanced abiotic stress tolerance, improved biotic resistance, increased yield and fiber quality, and broadened genetic diversity. By analyzing the taxonomy, geographic distribution, and evolutionary history of Gossypium species, this study explores the genetic basis of introgression, mechanisms of gene flow, and methods for detecting and analyzing introgressed genes. Additionally, historical and modern cases are examined to illustrate hybridization events and their impacts. On the molecular and genomic front, the study employs genomic tools to identify key genes and pathways involved in the introgression process. Although interspecific introgression shows great promise in breeding programs and genetic engineering, its implementation faces challenges. This study aims to guide future research by leveraging interspecific introgression to promote the conservation of Gossypium species and sustainable agricultural development, offering potential solutions for climate change adaptation.
