Quantitative Trait Loci (QTL) mapping has proven to be crucial in understanding and improving fiber quality in cotton, with the genus Gossypium attracting significant attention due to its economic importance in the global cotton industry. This study extensively discusses the genetic foundations of cotton fiber quality, including the main fiber quality traits, their genetic variability, and heritability. By comparing early and recent QTL mapping studies, this research illustrates progress and the identification of key QTLs, as well as how these QTLs perform under different environmental conditions. The study also explores the integration of QTL mapping into breeding programs and its impact on the cotton industry, highlighting successful case studies and identifying challenges and future directions. By identifying and locating the main genetic loci that affect fiber quality, this research aims to provide a scientific basis and technical support for cotton breeding, making the breeding process more precise and efficient.
