Foundation Plant Services, University of California, Davis


Foundation Plant Services (FPS) is a self-supporting service department in the College of Agricultural & Environmental Sciences at the University of California, Davis.  The FPS grape clean plant program was created in 1958 as a cooperative effort between the university, the USDA-ARS, and the wine and grape industry of California. 

FPS produces, tests, maintains and distributes premium disease-tested grapevine propagating material in the U.S.  FPS is also the home of the largest grape importation facility in the U.S., using state-of-the-art pathogen testing and disease elimination technology to successfully advance foreign grape selections through quarantine. 

FPS’ current Classic Foundation Vineyard collection contains the germplasm for the California Grapevine Registration & Certification Program. FPS plant material serves as primary source material for commercial increase of grapevines for the grape industry. The program is primarily geared toward the distribution of small quantities of commercially-important propagating stock to nurseries and others, who increase the stock for sale to commercial producers of grapes and grape products. The FPS collection currently contains over 750 grape varieties and 1200 clones (selections), which represent all regions of the United States and the world.

FPS is the headquarters for the NCPN for Grapes and in 2010 began development of the primary NCPN foundation vineyard collection at a site on the UC Davis campus called ‘Russell Ranch’. Plant material for this new foundation vineyard is qualified using guidelines specified in the ‘2010 Protocol’, which adopts a new stricter standard recommended in 2009 by the Board of the NCPN for Grapes.

The Russell Ranch vineyard is 100-acres on the UC Davis campus. All vines planted at Russell Ranch must go through a testing scheme designated “PROTOCOL 2010” which set a new, rigorous level for grapevine foundation material in the United States. To qualify as Protocol 2010 plant material, vines must be generated using microshoot tip culture and tested for an extensive list of pathogens. The first vines to qualify as Protocol 2010 vines were planted in 2011. There are now over 1000 vines planted at Russell Ranch that produce plant material for grapevine nurseries which provide clean planting material for growers nationwide.

NCPN LogoThe National Clean Plant Network (NCPN) is a voluntary association of specialty crop networks that have joined to promote the use of pathogen-tested, healthy plant material for food crops in the United States. The NCPN operates under the auspices of three agencies within the United States Department of Agriculture - Animal and Plant Health Inspection Service (APHIS), Agricultural Research Service (ARS) and National Institute of Food and Agriculture (NIFA).
