Growth and sporulation of avrRpv3− and avrRpv12−/3−Plasmopara viticola isolates on susceptible and resistant cultivars. Leaf discs of susceptible cultivars ‘Müller-Thurgau’ and ‘Riesling’, Rpv3-cultivars ‘Cabernet blanc’ and ‘Regent’, Rpv12-cultivars ‘Merlot Khorus’ and ‘Fleurtai’, Rpv12/Rpv3-cultivars ‘Soreli’ and ‘Sauvignac’ and the Rpv10-cultivar ‘Muscaris’ were inoculated with P. viticola isolates. Quantitative evaluation of sporulation of P. viticola isolates (A) avrRpv3− isolate and (B) VB (avrRpv12−/3−) isolate on leaf discs. Sporangia were counted 6 days post inoculation (dpi). Bars represent the average of three independent experiments (n = 63). Error bars show standard deviation. Kruskal-Wallis and Steel-Dwass-Critchlow-Fligner test was used for multiple pairwise comparison of the effect of the two different isolates on different cultivars. Means with the different letters (a, b, c) show significant differences for infection (p < 0.05). C Pictures of representative leaf discs of susceptible cultivar - ´Riesling´; Rpv3-cultivar - ´Cabernet Blanc´; Rpv12-cultivar - ´Fleurtai´; Rpv12/Rpv3-cultivar - ´Soreli´; Rpv10-cultivar - ´Muscaris´ were taken at 6 dpi with the avrRpv3− (top) and avrRpv12−/3− (bottom) isolate
