Diversity of Botryosphaeriaceae Species Associated with Grapevine Trunk Diseases in the Czech Republic

During a study of Botryosphaeriaceae species associated with grapevine trunk diseases in the Czech Republic, collection 22 Botryosphaeriaceae-like strains were isolated from four cultivars (Blaufränkisch, Pálava, Pinot Noir, and Welschriesling) distinct vineyards. Based on morphology DNA sequence data (ITS, tub2, tef), identified: Botryosphaeria dothidea, Diplodia mutila, D. seriata, Neofusicoccum parvum. These are reported for first time Republic. Relationships between vascular lesions particular highlighted this study. seriata was most frequently species, present all sampled cultivars, while mutila least frequent, only ‘Pálava’. The cultivar Noir tolerant host fungi.
