Economic crop plays an important role in the national economy and rural revitalization. Vegetables, fruit trees, tea trees, tropical crops, sugar and flowers are important economic crops. Due to human interference, climate change, population structure and the instability of ecological communities, the wild endangered resources are rapidly reduced, and some important rare resources are on the verge of extinction. However, the rare and endangered resources of economic crops such as vegetables are faced with bottleneck problems such as lack of collection and protection technology and imperfect protection system. It is urgent to carry out research and development of relevant technologies for rescue and protection. This paper mainly introduces the rare and endangered resources of the main economic crops including vegetables, fruit trees, tea, flowers and tropical crops about their protection, monitoring and utilization status, besides we also analyze their main endangerment mechanisms, put forward the protection strategies of the rare and endangered germplasm resources of the main economic crops.
