As an important food and feed resource, legume crops play an important role in ensuring food security, improving soil fertility and promoting sustainable agricultural development. Rich germplasm resources provide a key genetic basis for high-yield breeding of legumes. This study systematically sorted out the diversity characteristics of the current main germplasm resources of legumes, covering their geographical distribution, phenotypic variation and genetic background, and focused on analyzing important agronomic traits related to high yield, such as pod number, grain weight, stress resistance and nitrogen fixation ability. It further explored the specific application paths of diversity resources in modern breeding, including the introduction of excellent alleles, the development of pre-breeding materials, and the integration of marker-assisted selection and genomic selection technology. At the same time, the actual value of diversity germplasm in improving breeding efficiency and yield performance was explained through typical high-yield breeding cases. Fully exploring and accurately utilizing the genetic diversity of legumes is one of the core strategies to promote high-yield, stable yield and green development of legumes. This study hopes to provide theoretical support and practical reference for the construction of efficient breeding systems and the creation of new germplasm in the future.
