Abstract Common oat (Avena sativa L.) cultivars and breeding lines grown in Western Europe and North America were tested against twelve Erysiphe graminis f. sp. avenae mildew isolates collected in Germany and Denmark. These isolates were selected for their ability to produce differential response patterns permitting characterization of five oat mildew resistance (OMR) groups. From a total of 259 cultivars and lines tested 173 accessions showed susceptible responses, 48 accessions were characterized by susceptible or intermediate responses and 38 accessions revealed isolate-specific resistance response patterns. Eight cultivars and lines had resistance patterns of OMR group 1, six cultivars of OMR group 2, and eleven cultivars of OMR group 3. Two cultivars, each possessed resistance patterns corresponding to OMR groups 1 + 3 and 2 + 3 in combination, respectively. Three cultivars exhibited the response pattern of OMR group 3 in association with an additional unknown resistance. Eight cultivars and lines showed a resistance response pattern not yet detected in the documented OMR groups.
