Abstract
Disease response pattern of 127 T1B·1RS translocation and substitution wheat cultivars, possessing powdery mildew resistance gene Pm8 and leaf rust resistance gene Lr26 located on rye chromosome arm IRS, revealed that sixteen of these cultivars express Lr26, but not concomitant Pm8 resistance. The mode of inheritance studied in the F1, F2 and F3 generations, and involving hybrids of cultivars Agra, Florida, Olymp, Sabina and Tjelvar not expressing Pm8 resistance indicated inhibition of resistance gene Pm8 by a dominant suppressor.
