In 1999, the National Clonal Germplasm Repository at Corvallis, Ore., was assigned to preserve the hardy Actinidia Lindl. resources for the U.S. Dept. of Agriculture, Agricultural Research Service, National Plant Germplasm System. The fuzzy kiwifruit [A. deliciosa (A. Chev) C. F. Liang et A. R. Furguson] and other less cold-hardy Actinidia species, remain at the Davis Repository. The hardy Actinidia, commonly called Chinese gooseberries or hardy kiwifruit, encompass two taxonomic sections, Leiocarpae and Maculatae, and include about 13 described species. These perennial vines are natives of Asia and have been developed and cultivated in Lushan, Wuhan, and Guilin, China; Motueka, New Zealand; Kagawa Prefecture, Japan; Vladivostok, Russia; and California, Maryland, Michigan, Minnesota, New Hampshire, and New York in the United States. Thus far, the Corvallis Repository has established representatives of six species, A. arguta (Siebold & Zucc.) Planch. Ex Miq., A. callosa Lindl., A. kolomikta (Maxim.&Rupr.) Maxim, A. melanandra Franch., A. polygama (Siebold & Zucc.) Maxim., A. purpurea Rehder and 60 cultivars. These clones will be preserved as potted plants under screen. They will also be fruited and evaluated as trellised plants in the field. The repository plans to expand the species diversity of the collections. Plant requests for dormant scionwood or spring softwood cuttings are available by contacting the Corvallis Repository Curator.
