In the past 20 years (1999-2019), the Ministry of Agriculture and Rural Affairs (MARA) had coordinated researchers in agricultural environmental protection agencies, universities and institutes to carry out the activities on the field surveys, collections, constructions and monitoring of in-situ conservation, information system establishment etc. Several major achievements have been made, including: (i) accomplishing national-wide survey of 80 crop wild relatives, such as discovering the distribution zones of wild orchid and wild tea trees; (ii) collecting 44737 germplasm accessions of 60 important wild relatives, which have subjected for the conservation in ex-situ Genebank and which are monitorable using a GPS/GIS information system; (iii) Establishing 205 in-situ conservation sites which refer 65 species in 28 provinces, as well as the technical monitoring and early warning system on the dynamic analysis of the collected data from 15 in-situ conservation sites. However, there are some problems remained in the conservation of agricultural wild plants. Only lower proportion of species/germplasm resources have been investigated without an overview coordinate. The technique issues on management have become the bottleneck restricting the in-situ conservation. Therefore, we suggest the development of management techniques of in-situ conservation sites to support local managers in application. The techniques should be feasible for different plants and different sites respectively, which indicates that the in-situ conservation will be changed from increasing the quantity to improving the quality.
