The biotrophic oomycete Plasmopara viticola is the causal agent of downy mildew, one of the major grapevine diseases.We report here a successful strategy to cross compatible strains of this pathogen and obtain a large viable progeny.We used this method to Belt study the offspring between two P.viticola strains able to overcome Play Equipment two major grapevine resistance factors (Rpv3, Rpv10).

Thanks to the genomic resources now available, we will genotype this progeny to build an unprecedented linkage map and uncover the genomic bases of grapevine resistance breakdown displayed by P.viticola virulent strains.
