Collaboration for Plant Pathogen Strain Identification

“CPPSI is a science based, vegetable seed industry initiative developed to standardize the identification of plant pathogen strains and races based on sets of host differentials and reference pathogen strains.”

Pathotyping information is available at the Collaboration for Plant Pathogen Strain Identification website housed at the University of California. CPPSI described the pathogen strains and the differential host reactions in white papers:

• Melon Fusarium oxysporum f. sp. melonis: Guidelines for the Identification of races of Fusarium oxysporum f. sp. melonis using Differential Melon Lines
• Fusarium oxysporum f. sp. niveum: Guidelines for the Identification of races of Fusarium oxysporum f. sp. niveum using Differential Watermelon Lines
