The Clean Plant Center Northwest holds and maintains a foundation collection of virus-tested, G1-level Grapevine accessions at Washington State University’s Irrigated Agriculture Research and Extension Center in Prosser, WA. These accessions are maintained in insect-proof screenhouses to prevent reinfection, and are regularly tested to ensure their cleanliness. Accessions held in the foundation collection are available for sale and distribution to growers and nurseries across the United States.
All available accessions have undergone a series of diagnostic assays to ensure that they are free of economically important viruses and virus-like organisms. Please click on the following link for a list of currently available Grapevine accessions.
Please note that this list contains only accessions that have reached full release status and are presently available; accessions that are in progress, or accessions that have been removed, are not shown.
