Twenty-five accessions of Aegilops species were inoculated with Erysiphe graminis f. sp. tritici, f. sp. secalis, and f. sp. agropyri. The pattern of resistance/susceptibility was various and similar to that between cultivars and races. Genetic analysis using the gene-for-gene relationship suggested that accessions of Ae.bicornis and Ae. cylindrica carry Pml5, a gene for resistance to f. sp. secalis and f. sp. agropyri found in the D genome of common wheat. Evolutionary implications of these results were discussed.
