Eighteen disease-tested, black currant cultivars ( Ribes nigrumL.) and one jostaberry ( R. x nidigrolariaBauer) were released in December 1998 from the U. S. National Plant Germplasm Quarantine Office (NPGQO) in Beltsville, Maryland. These cultivars were received at the quarantine office between 1989 and 1993 from collaborators in Poland, Russian Federation, Switzerland, and the United Kingdom. Foreign Ribesfrom Europe are prohibited to enter the United States except when processed through this quarantine facility. These 19 cultivars passed the rigorous Animal and Plant Health Inspection Service (APHIS) testing protocol and were released to the U. S. Department of Agriculture, Agricultural Research Service, National Clonal Germplasm Repository (NCGR) in Corvallis, Oregon, for long term preservation in their Ribescollection. Plant material can be requested for research and evaluation by contacting the Curator at the Corvallis Repository.
