Keywords Cotton breeding; Genomics; High-throughput sequencing, Multi-omics integration; Synthetic biology 1 Introduction Cotton (Gossypium) stands as one of the most vital crops globally, playing a pivotal role in both agriculture and industry. As a primary source of natural fiber, cotton supports the textile industry, which is a significant economic driver in many countries. The plant's by-products, such as cottonseed oil and meal, are valuable for food and livestock feed. Cotton cultivation provides livelihoods for millions of farmers, particularly in developing regions, underscoring its socioeconomic importance. Enhancing cotton's yield, fiber quality, and resistance to pests and diseases can therefore have substantial economic and social benefits (Yang et al., 2020). Genome sequencing has revolutionized the field of plant breeding by providing comprehensive insights into the genetic makeup of crops. This technology enables the identification of genes associated with desirable traits, facilitating targeted breeding strategies. In the context of cotton, genome sequencing has been instrumental in understanding the complex genome of different Gossypiumspecies. By decoding the genetic information, researchers can identify markers for traits such as fiber quality, yield potential, and resistance to biotic and abiotic stresses (Huang et al., 2021). The integration of genome sequencing with traditional breeding methods accelerates the development of superior cotton varieties, ultimately enhancing agricultural productivity and sustainability (Ma and Cao, 2018). This study comprehensively analyzes the advancements in cotton species genome sequencing and its impact on cotton breeding. The research covers historical milestones in cotton genome research, the latest technological advancements, and achievements in sequencing different cotton genomes. Additionally, the study explores the practical applications of genome sequencing in cotton breeding, including case studies of successful breeding strategies. The challenges and limitations faced by cotton genome research are also discussed, along with suggestions for future improvements. By elucidating the transformative potential of genome sequencing in enhancing cotton breeding practices and meeting the global demand for high-quality cotton, this study provides a reference for continued investment in genomic technologies to achieve sustainable development in cotton agriculture.
