Powdery mildew caused by the fungal pathogen Erysiphe necator is a global disease that reduces yield and quality in grapes (Vitis vinifera L.). Most grape cultivars are susceptible to this pathogen and thus the selection of powdery mildew resistant cultivars is a major objective of grape breeding programs. In this study, we evaluated powdery mildew resistance of a diverse set of 28 commonly cultivated local and international V. vinifera cultivars after artificial inoculations with Erysiphe necator. Of these, 7 cultivars were found to be resistant while 10 and 11, were found to be moderately resistant and susceptible to powdery mildew, respectively. |
