The Collaboration for Plant Pathogen Strain Identification (CPPSI) is a science-based, vegetable seed industry supported initiative to standardize the identification of plant pathogen strains and races based on sets of host differentials and reference plant pathogen races and strains.
Benefits of CPPSI Membership
- Priority services for members as a center of plant pathogen strain resources and information and provides biannual overviews of these activities.
- Member logo displayed on CPPSI website with a link to member’s website.
- Provides a voice for members to address International Seed Federation (ISF) pathogen strain questions and input on international initiatives for consistent strain naming.
- Provides access to reference materials and any written overviews that facilitate the identification of plant pathogen strains and races
Available CPPSI Information
The web-based CPPSI system provides access to standardized reference strains, seeds of differential hosts and informative instructional guides for the use in identification of plant pathogen strains important in vegetable production. Visit our White Papers section for more information. These materials can also be used to start up disease resistance screening programs. The CPPSI director also provides information, insights and resources for the understanding of disease resistance terminology, pathogen coding in collaborations with the International Seed Federation, European Seed Association, GEVES-MATREF and Naktuinbouw.
