New Cladosporium races on tomato

Writtern by contributeur

Following the epidemiological study under the umbrella of ISF (link to the website:, in which GEVES was a partner, 5 new races of Passalora fulva (ex Cladosporium fulvum) were identified. These new races break the resistance conferred by the Cf-9 resistance gene, which is frequently used in commercial tomato varieties because it has not been overcome in the field until now. This work also provided an opportunity to define a new harmonised coding system. 

These new races are now available in MATREF, and resistance evaluation tests are possible at GEVES.
