Cultivated oat ( Avenu sativa L.) varieties and lines grown in Northern and Eastern European countries were tested for powdery mildew resistance using eleven Erysiphe graminis f. sp. avenue isolates, which possess the ability to differentiate the five oat powdery mildew resistance (OMR) groups. About 5%) from a total of 207 accessions possessed resistance which was attributable to either documented resistance or to disease response patterns previously not yet detected. Five cultivars and lines showed the resistance of OMR group I, one cultivar possessed the resistance of OMR group 3, one line revealed the resistance of OMR 3 in combination with an additional resistance and 3 cultivars exhibited a resistant response pattern not yet characterized.
