Description
  • National barley powdery mildew virulence surveys were co-ordinated through COST817 on a European scale from 1993 to 1999 to allow comparison of results across national borders. The frequencies of virulence matching resistance genes Mla1, Mla3, Mla6, Mla7, Mla9, Mla12, Mla13, Mlk, MlLa and Mlg were moderate to high in most years and countries. Generally, no increase in aggressiveness against Mlo-resistance was detected, but change may be under way as particular isolates of British origin gave higher infection levels on Mlo-resistant varieties than did other groups of isolates. Multi-location field trials were established in 1998 and 1999 in order to study powdery mildew resistance in barley genotypes in different environments. The trials showed large interactions of location and phenotypic expression of the resistance.
