Evaluation of Northern Grape Hybrid Cultivars for Their Susceptibility to Anthracnose Caused by <i>Elsinoe ampelina</i>

Fig. 6. Relative resistance of grape cultivars to Elsionoe ampelina as assessed in potted plant assays. The value of each bar represents the average number of lesions on 36 inoculated leaves. The bars with the same letters are not significantly different according to the Tukey test at the 0.05 level of confidence. The categories of susceptibility were based on the cluster analysis.
