The crop wild relative Fragaria vesca as source of resistance against strawberry anthracnose.

ABSTRACT: The genetic diversity of Fragaria species in situ has great potential for breeding resistance in cultivated strawberries against anthracnose disease. In this study, we investigated the host-pathogen interactions of 72 F. vesca genotypes of various German origins to identify new resistance to Colletotrichum, one of the most economically important genera of pathogens in F. × ananassa cultivation. The host-pathogen interactions were monitored by symptomatic scoring after spray-inoculation of F. vesca genotypes with monoconidial Colletotrichum isolates of different species recently determined in German strawberry fields. We observed significant variation in host-pathogen interaction, ranging from host genotypes exhibiting resistance to a single pathogen strain, to those demonstrating broad-spe
