Polyploidy plays a crucial role in crops of the Triticeae tribe (such as wheat, barley, and rye), significantly influencing their evolutionary history and agronomic traits. Through mechanisms such as genome duplication, gene rearrangement, and functional diversity, polyploidy has driven the adaptability and productivity of Triticeae crops. Understanding the genetic mechanisms of polyploidy is essential for improving these important crops. This study explores the genetic mechanisms underlying the formation of polyploidy in Triticeae and its impact on agronomic traits. By analyzing post-polyploidization genomic changes, epigenetic modifications, and gene expression regulation, this research reveals how polyploidy promotes the improvement and enhanced adaptability of Triticeae crops. Additionally, it summarizes the applications of polyploidy in modern breeding and discusses its potential role in crop breeding and climate change adaptation in the future. Polyploidy not only has profound effects on the evolution of Triticeae crops but also provides important genetic resources for crop improvement. By gaining a deeper understanding of the molecular basis of polyploidy, breeders can leverage its advantages to enhance crop yield, disease resistance, and drought tolerance. Furthermore, polyploidy holds great significance in addressing complex genetic patterns and optimizing breeding strategies, contributing to the solutions for the challenges faced by modern agriculture.
