Certification levels.

All propagative material produced under this program must be derived from Generation 1 stock and grown under conditions that mitigate the risk of reinfection. Generation 1 level material is produced at the Clean Plant Center-Northwest (CPC-NW) at Washington State University, or other grapevine foundation facilities within the National Clean Plant Network (NCPN) and approved by the department. The accession numbers relating to the single grapevine source at CPC-NW or other approved facilities must be retained for tracking purposes. At each stage of propagation, progeny plants drop to a lower certification level.
