The occurrence of chestnut blight (Cryphonectria parasitica) was studied in 2011–2012 at 13 locations in the main chestnut growing areas of Romania. Infections were detected at four localities. The symptoms and the fungus were detected on European chestnut (four localities) and also on oak trees (two localities). A total of 89 isolates of C. parasitica were isolated and characterised. Based on canker and isolate morphology (culture morphology and the Bavendamm test), both virulent and hypovirulent samples were isolated; hypovirulent isolates were found at only one locality. Two vegetative compatibility types corresponding to EU-12 and EU-2 were identified among isolates. Both mating types were found, with a dominance of MAT-1 in southern Romania and MAT-2 in northern Romania.
