Abstract
Important microevolutional processes have taken place in the wheat powdery mildew population over the last thirty years. There has been a considerable change in the race composition of the pathogen population and in the prevalent races. Of the 78 races identified, only eleven have “lived” for more than 15 years. Many races were only isolated in one or two years. The number of virulence genes rose from 2.03 in 1973 to 5.63 in 1993. On the basis of race composition and virulence the wheat powdery mildew population between 1971 and 1999 can be divided into four distinct groups. A large proportion of the powdery mildew isolates are virulent to most resistance genes. Complete resistance is provided by resistance genes Pm4a (Khapli) and partial resistance by Pm2+Mld (Halle st. 13471), Pm4b+ (TP 315/2) and Pm1+2+9 (Normandie). The majority of cultivated varieties carry the resistance gene Pm8 due to the presence of the 1B/1R translocation.
