Slk. Hsam et al., Genetic studies of powdery mildew resistance in cultivated oat (Avena sativa L.) II. Cultivars and breeding lines grown in Northern and Eastern Europe, HEREDITAS, 129(3), 1998, pp. 227-230
Cultivated oat (Avena sativa L.) varieties and lines grown in Northern and
Eastern European countries were tested for powdery mildew resistance using
eleven Erysiphe graminis f. sp. avenae 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 attributa
ble to either documented resistance or to disease response patterns previou
sly not vet detected. Five cultivars and lines showed the resistance of OMR
group 1, one cultivar possessed the resistance of OMR group 3, one line re
vealed the resistance of OMR 3 in combination with an additional resistance
and 3 cultivars exhibited a resistant response pattern not yet characteriz
