Abstract

In the progeny of a hybrid between monotelosomic line 3B of 'Chinese Spring' wheat and 'Chinese Spring' - Aegilops longissima ditelosomic addition line 'G' a cytologically stable strain was selected consisting of 20 wheat chromosome pairs, one pair of telosomic chromosome 3BL and one pair of telosomic longissima chromosome 'G'. Inoculating 'Chinese Spring' - Aegilops longissima addition and substitution lines with ten different powdery mildew isolates, partial resistance was observed. The infection grade as well as the number of spores/cm2 leaf area were significantly reduced.
