The National Tropical Plant Germplasm Repository, supported by the Institute of Tropical Crop Variety Resources of the Chinese Academy of Tropical Agricultural Sciences (CATAS) and jointly constructed by 11 units including the Institute of Fruit Tree Research of the Guangdong Academy of Agricultural Sciences and Hainan University, aims to provide information and physical support for scientific and technological innovation in tropical crop seed industry, increase the income of farmers in hot regions, alleviate poverty, the "One Belt One Road" initiative and the National Tropical Agricultural Science Centre. The National Centre for Tropical Agricultural Sciences (NCTAS) provides information and physical support for tropical crop germplasm resources. The National Tropical Plant Germplasm Repository consists of a national medium-term tropical crop germplasm preservation repository, a medium-term tropical forage preservation repository and 12 national nurseries, covering 24 crops in nine categories, including rubber trees, tropical forage, tropical fruit trees, tropical oilseeds, tropical aromatic beverages, southern medicine, tropical grains, tropical flowers and tropical special vegetables, with more than 26,000 copies of resources, accounting for more than 90% of the total tropical crop germplasm resources in China. The resources account for more than 90% of the total amount of tropical crop germplasm resources in China. It has built an efficient management system and a stable human resources team, a conservation system that combines centralized conservation in germplasm banks and moderate distribution in germplasm nurseries, a technical specification system for the unified description of germplasm resources of major tropical crops, and an integrated system for the conservation and utilization of China's tropical crop germplasm resource information network, ensuring the efficient operation and sustainable development of the national tropical crop germplasm resource bank.
