The Clean Plant Center Northwest holds and maintains a foundation collection of virus-tested, G1-level Pome and Stone Fruit 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 Public Pome and Stone fruit 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.

- Actual shipping cost (calculated at time of shipment)
- Phytosanitary certificate (if applicable) at $175 per order shipped in the US, and $200 per order shipped internationally
Payment: Once the shipment is prepared, an invoice will be sent to the customer. This may be payed either by credit card via our secure payment link, or by sending a check for invoiced amount made out to CPCNW/WSU to 24106 N Bunn Rd, Prosser, WA 99350. Orders will not be shipped until payment has been received.
We have made every effort over the decades to insure access to our collection for the international community. Recently, there have been dramatic changes in the management of phytosanitary requirements for exports to the majority of countries around the world. The time, effort, and cost involved in ensuring that every shipment is in compliance with the receiving countries phytosanitary regime is becoming increasingly prohibitive.
As a result, the CPCNW will only guarantee distribution to the U.S. and Canada, and to countries whose phytosanitary requirements can be met in-house by the CPCNW. Requests to ship propagative material to counties that require additional testing and/or declarations for pests and diseases not tested for by CPCNW will be declined.
In addition, to ensure sufficient time to research and confirm the phytosanitary requirements the CPCNW requests that the customer send their import permit and list of additional declarations, in English, to the CPCNW no less than three (3) months prior to the end of the sale request period. Import permits and additional declarations sent less than three (3) months prior to the end of the sale request period will only be accepted at the discretion of the CPCNW Director.
