Abstract:

As an important medicinal and edible plant in China, Platostoma palustre possesses multifaceted value in the fields of medicine, food, and chemical industry, yet issues such as limited germplasm diversity, lagging elite cultivar improvement and extensive cultivation practices have hindered the further development of its industry. This review synthesizes global research progress on germplasm resource distribution, varietal breeding, and cultivation techniques of Platostoma palustre, while systematically analyzing the bottleneck problems such as lack of germplasm resources, bottleneck of breeding technology and non-standard cultivation management in the development and utilization of germplasm resources and large-scale planting in China. Based on the current research trends and industrial development needs, this paper proposes that the protection and utilization of the germplasm resources should be strengthened. It suggests innovating germplasm resources through techniques such as chemical mutagenesis and distant hybridization, establishing a germplasm resource evaluation system based on molecular markers, and conducting systematic phenomics analysis. Additionally, it advocates adopting multi-channel breeding strategies including traditional breeding and modern molecular breeding technologies, while formulating standard cultivation technical regulations. The study provides references for the innovation of germplasm resources, efficient breeding, and improvement of standardized cultivation techniques for Platostoma palustre in China.

Key words: Platostoma palustre, germplasm resources, variety breeding, cultivation techniques
