1) Plant genetic resources for food and agriculture (PGRFA) are important for further crop breeding and adaptation to changing environments. There is a long history of international exchange of PGRFA.
2) The International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) established a Multilateral System (MLS) in 2001 to facilitate access to PGRFA and ensure benefit sharing.
3) The MLS includes 64 major crops and consists of plant genetic resources held by governments and in public collections. It uses a Standard Material Transfer Agreement to allow access for research, breeding and training.
