"Results of scoring resistance of 35 selected spring barley varieties to powdery mildew in 307 variety trials of the Central Institute for Supervising and Testing in Agriculture exhibiting high powdery mildew severity were analyzed. The varieties can be divided into two groups: the varieties that could not induce changes in the pathogen population (the varieties with no effective resistance gene and varieties carrying the gene mlo) and the varieties possessing major resistance genes(a total of 12 Ml-genes: a1, a3, a6, a7, a9, a12, a13, at, k1, La, g and (Kr)) to which the pathogen population adapted in 1971-2000. The time slope of decreasing resistance of varieties is described. Importance of individual evolutionary forces (mutations, migration, direct selection, indirect selection and recombinations) on erosion of efficiency of respective major resistance genes and effects of the pathogen adaptation" . .
