CWR China is a collaborative project jointly funded by the UK Department for Environment, Food and Rural Affairs (Defra) and the Ministry of Agriculture of the People’s Republic of China (MOA) under the China–UK Sustainable Agriculture Innovation Network (SAIN, http://www.sainonline.org/English.html) initiative. The purpose of this three-year project is to develop conservation and use strategies for crop wild relative (CWR) species of China to secure and provide access to the genetic diversity of the most important wild plant resources needed for food security and sustainable development in China—in particular to mitigate the impact of climate change. The project involves representatives from five partner institutes—the Institute of Botany, Chinese Academy of Sciences (IBCAS), the China Agricultural University (CAU), the Institute of Crop Science, Chinese Academy of Agricultural Sciences (CAAS), Fudan University in Shanghai, and the University of Birmingham in the UK.
