More than20 countries are involved in the survey of national collections, the elaboration of the different descriptors fortheir documentation, and the development of the European Prunus database (EPDB). At present, the permanentcollections gathered more than 8000 accessions for which passport and characterization data are registered in theEPDB. EPDB has been made available on the Internet.
