The process of testing and eliminating viruses in fruit trees, grapevines and hops is time consuming. Only a certain number of cultivars from each commodity can be entered into the program each year.
Introductions accepted into the program can be
- Private Domestic
- Private Foreign
All introductions undergo virus testing and therapy if needed before they are released or put into our retention program.
“Public” refers to material that is freely distributed without license fees or restrictions. Submissions by public breeding programs from recognized state and federal institutions will also be considered “public” for these purposes. Each submitting sponsor or organization is limited to four introductions per year.

Fruit Tree Introductions
Public and Domestic Fruit Tree Varieties- For public and private domestic varieties, send four budwood sticks with 10 buds each, collected from a single tree in December–January (northern hemisphere) or in May-June (southern hemisphere).
Foreign Fruit Tree Varieties – To introduce foreign varieties, contact CPCNW Coordinator to obtain a copy of our import permit and a label for shipping the samples to USDA-APHIS in Beltsville, Maryland for inspection. This inspection is REQUIRED. CPCNW will not accept foreign material that has not been released by APHIS. Send four budwood sticks with 10-15 buds each, collected from a single tree (sticks should be the thickness of a pencil).
Required forms for ALL fruit tree introductions
Budwood and reference trees from varieties that test free of all targeted viruses in the first year of our testing may qualify for provisional release with the approval of the budwood recipient’s State department of agriculture (USDA-APHIS permission would also be required for foreign introductions). This allows the recipient to establish mother plants in their nursery block only. Full release permission (based on second- and third-year of testing) is required before plants can be distributed to grower by the nursery.
Please contact the CPCNW coordinator with any questions about the fruit tree introduction process.
On an annual basis the Clean Plant Center Northwest (CPCNW) allows for the limited introduction of new grapevine selections (public or proprietary) at a subsidize rate. Introduction requests are accepted from February 1 to November 30 annually.
The priority ranking for applications is:
- Public varieties
- Proprietary varieties owned/Sponsored by a Washington, Oregon or Idaho resident
- Proprietary varieties owned/Sponsored by a resident in the U.S. outside of Washington, Oregon or Idaho
“Public” refers to material that is freely distributed without license fees or restrictions. Submissions by public breeding programs from recognized state and federal institutions will also be considered “public” for these purposes.
Applications will be reviewed by the Foundation Block Advisory group for approval or rejection in January or February 2018, ten submissions will be selected for introduction at the subsidized rate. Successful applications will be notified by the CPCNW Coordinator in March 2018.
Introduction requests must be sent to the CPCNW at CPCNW@WSU.EDU. Requests must include:
- Submitter’s Name, Address and Phone Number
- Public or Proprietary Selection
- TTB Approved Prime Name
- Synonyms (if known)
- Clonal Number
On an annual basis, we allow for a limited introduction of new selections (public or sponsored). Selection nominations are due by the first Friday of January each year. For a reduced fee, anyone may propose a public selection, but approval will be given through the NCPN Tier 2 Hop committee. For a fee, sponsored selections can be submitted, but they are also subject to the approval of the Tier 2 committee. Approved sponsored selections will only be distributed with approval and direction from the sponsor.
If you would like to request a public or sponsored selection, please review and submit the Hop Nomination form. Prior to submitting the hop sample(s) for pathogen testing, a signed Introduction Agreement must be submitted.
