Abstract

Disease response pattern of 127 TIB ·1RS translocation and substitution wheat cultivars, possessing powdery mildew resistance gene Pm8 and leaf rust resistance gene Lr26 located on rye chromosome arm 1RS, 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.
