Fifty‐five isolates of P. antirrhini urediospores were collected from around the world. These isolates were used to inoculate the leaves of 10 cultivars of Antirrhinum majus. Two races of P. antirrhini were identified (α and β). None of the cultivars challenged exhibited resistance to isolates of Race β. Some cultivars were resistant to Race a. Resistance was inherited in a manner consistent with the existence of a dominant, nuclear allele at a single locus.
