Growth and sporulation of virulent and avirulent Plasmopara viticola isolates on susceptible and Rpv3 cultivars. Leaf discs of Rpv3–1 cultivars (a, e) ‘Cabernet blanc’ and (b, f) ‘Regent’, (c, g) the Rpv3–1/Rpv3–2 cultivar ‘Calardis blanc’ and (d, h) the susceptible cultivar ‘Müller-Thurgau’ were inoculated with the avirulent (avrRpv3+) (top) and virulent (avrRpv3ˉ) (bottom) P. viticola isolates. Pictures of representative leaf discs were taken at 6 days post inoculation (dpi). (I) Quantitative evaluation of sporulation of P. viticola isolates on leaf discs. Sporangia were counted 6 dpi. Bars represent the average of three independent experiments. Error bars show standard deviation. ANOVA was used to determine the effects of cultivar and treatment (the two isolates) on the amount of sporangia per ml*103 and then means were compared by Tukey’s HSD (Honestly Significant Difference) test. For ANOVA and Tukey testing, sporangia count data was transformed to log values to fulfill criteria of normal distribution. Means with different letters (a, b, c, d) are significantly different (P < 0.05)
