Polyploidy, the condition of possessing more than two complete sets of chromosomes, has played a pivotal role in the evolution and diversification of cotton (Gossypium spp.). This study explores the impact of polyploidy on the genetic and phenotypic diversity of cotton species. By analyzing genomic data, historical breeding records, and evolutionary patterns, we elucidate how polyploidy has contributed to cotton's adaptability, stress resistance, and fiber quality. We discuss the mechanisms of polyploid formation, the evolutionary advantages conferred by polyploidy, and the role of polyploidy in the domestication and improvement of cotton varieties. Our findings highlight the significance of polyploidy in enhancing genetic diversity, which is crucial for future cotton breeding programs aimed at sustainability and resilience.
