Mean values of disease incidence (plain bars, left axis, small letters) and severity (pattern bars, right axis, capital letters) evaluated in nine different Vitis vinifera genotypes 7 days after inoculation with Plasmopara viticola. Bars represent standard error of the mean. Different letters denote significant differences according to the Tukey’s test (p ≤ 0.05). Grapevine genotypes: CHA = Chasselas, ALE = Aleatico, CAN=Canaiolo nero, TRE = Trebbiano toscano, ROS = Rossetto, ROM = Romanesco, SYL = accession of V. vinifera subsp. sylvestris, ISA = Isabella, SOL = Solaris
