Abstract:Isolates of powdery mildew were subjected to recurrent selection on partially resistant barley cultivars for 76 inoculation cycles over three years. Previous intermediate tests on up to 32 cycles for adaptation to overcome the host resistance revealed a trend towards adaptation to the cv. 7204 recurrent host in infection frequency data but not towards cv. Golden Promise or 9319, Subsequent cycles demonstrated adaptation to these latter hosts also. Copyright © 1992, Wiley Blackwell. All rights reserved
