Interpretive Summary: This chapter summarizes the status of strawberry foundation plant material at two federal North American facilities. The Canadian Clonal Genebank (CCG), in Harrow, Ontario, is under the jurisdiction of Agriculture and Agri-Food Canada while the National Clonal Germplasm Repository (NCGR) at Corvallis, Oregon, is part of the United States Department of Agriculture, Agricultural Research Service National Plant Germplasm System. Both locations preserve wild and cultivated plants and seeds. The pathogen-negative plants are stored in aphid-proof screenhouses and propagated for evaluation in field collections. Tissue cultures for the most diverse plants in the collection are maintained for 3 to 5 years in refrigeration, re-propagating when necessary. Methods have been developed for preserving small plant parts in liquid nitrogen for the long-term. Strawberry plants are distributed freely to researchers and breeders throughout the world. Quarantine regulations are met. Rooted strawberry plants or runners are available during the summer. Seed and tissue cultures can be shipped at any time. Special arrangements can be made for pollen. Both of the facilities collaborate with each other whenever possible to enhance conservation efforts of this important crop.

Technical Abstract: This chapter summarizes the status of Fragaria germplasm at North American Genebanks. Two major genebanks, the Canadian Clonal Genebank (CCG), in Harrow, Ontario, is under the jurisdiction of Agriculture and Agri-Food Canada while the National Clonal Germplasm Repository (NCGR) at Corvallis, Oregon, is part of the United States Department of Agriculture, Agricultural Research Service National Plant Germplasm System. Both genebanks preserve wild and cultivated plants and seeds. The pathogen-negative plants are stored in aphid-proof screenhouses and propagated for evaluation in field collections. Tissue cultures of the Fragaria core collection are maintained for 3 to 5 years in refrigeration, re-propagating when necessary. Protocols have been developed for cryogenic preservation of meristems for the long-term remote base collection. Strawberry germplasm is distributed freely to researchers and breeders throughout the world. Importation phytosanitary regulations are met. Rooted strawberry plants or runners are available during the summer. Seed and in vitro cultures can be shipped at any time. Special arrangements can be made for pollen requests. Both of the genebanks collaborate with each other whenever possible to enhance conservation efforts of this important crop.
