This study presents a meta-analysis of yield-related genetic markers in cotton, focusing on their historical development, current applications, and future prospects. Advances in genetic marker technologies, including the use of SSRs, SNPs, and high-throughput sequencing, are explored, alongside their association with key yield traits such as boll size, lint weight, and plant height. Marker-assisted selection (MAS) and genomic selection (GS) are evaluated for their roles in improving breeding efficiency. A case study highlights the successful implementation of MAS in cotton breeding programs and the associated challenges. This analysis identifies significant markers and consistent quantitative trait loci (QTLs) across diverse studies, providing insights into emerging trends and practical applications. The study concludes by emphasizing the integration of advanced technologies, the importance of collaborative research, and actionable recommendations to enhance the role of genetic markers in sustainable cotton breeding. These findings offer valuable guidance for researchers and breeders aiming to address future challenges in cotton productivity.
