The application of genome-wide association studies (GWAS) in molecular breeding of leguminous crops has shown great potential, despite technical and methodological challenges. These challenges include the need to process and analyze large-scale genetic data, the difficulty of ensuring high-quality genotypic and phenotypic data, and the complexity of controlling the effects of population structure and genetic background. Future development directions of this study may focus on developing more efficient data analysis algorithms, utilizing machine learning and artificial intelligence technologies, developing high-throughput phenotyping technologies, and integrating multi-omics data to reveal deeper molecular mechanisms of trait formation. Elaborate. It aims to discover that advances in GWAS and molecular breeding technologies are of great significance for increasing global food production and promoting agricultural sustainability, especially in improving leguminous crop yields, disease resistance and adaptability. The development of these technologies not only accelerates the cultivation of new varieties, but also helps reduce the use of chemical fertilizers and pesticides and promotes the process of ecological agriculture.
