Abstract excerpt

KEY MESSAGE: A novel locus for grapevine resistance to Plasmopara viticola (Rpv32) was identified on chromosome 14 in the East Asian wild species Vitis coignetiae and compared with other resistances. One of the most devastating diseases in viticulture worldwide is downy mildew, caused by an obligate biotrophic oomycete, Plasmopara viticola. While fungicides are widely used to prevent yield losses, their...
