According to the results of phytopathological evaluation and progeny testing of winter wheat strains collection of different origin some donors and sources of septoria leaf blotch (Septoria tritici Rob. ex Desm) resistance have been found under the environment of the South of Ukraine. Among them there are several winter hard wheat varieties and the winter bread wheat lines obtained from interspecific hybridization with Aegilops cylindrica,Triticum dicoсcoides, Triticum erebuni. It was determined that the resistance to S.tritici is controlled by two dominant complementary acting genes or by a single dominant. Indexes, characterizing resistance and tolerance of wheat plants to the pathogene have been defined to estimate breeding material.
