With the advancement of molecular breeding technologies, genetic maps have become a crucial tool in un-covering the genetic basis of cotton fiber quality and have played a key role in trait improvement. This study reviews the applications of genetic maps in the research of cotton fiber quality traits, highlighting the pro-gress in quantitative trait locus (QTL) mapping, genome-wide association studies (GWAS), and mark-er-assisted selection (MAS). It also explores how genetic maps reveal the genetic mechanisms related to cot-ton fiber quality and enhance breeding efficiency. The study finds that genetic maps provide essential tools and methods for understanding and improving cotton fiber traits. Through precise localization of genes con-trolling fiber traits, genetic maps offer valuable molecular markers for molecular breeding in cotton, advanc-ing the development of high-quality cotton varieties. With the development of high-density genomic maps and genomic selection (GS) technologies, genetic maps are expected to play an even more significant role in future cotton improvement. The integration of genetic maps with gene editing technologies could further ac-celerate the precision and efficiency of cotton breeding.
