Genetic Diversity Research of Yam Germplasm Resources

Abstract

Yam (Dioscorea spp.), a versatile economic crop used both as food and medicine, is widely distributed globally, particularly in tropical and subtropical regions. Its abundant germplasm resources provide a crucial foundation for genetic diversity research. This paper reviews the latest advances in the genetic diversity study of yam germplasm resources, focusing on research methods and outcomes based on morphological traits, cytological markers, and molecular markers. By analyzing the application and effectiveness of these research methods, this paper summarizes key findings in yam genetic diversity research and proposes future research directions, aiming to provide theoretical support and technical guidance for yam genetic improvement and germplasm resource conservation.
