For the period of 2020, the species composition of winter wheat leaf blotch pathogens on the territory of the Central Chernozem region was studied. It is shown that the  Zymoseptoria tritici  species dominates in the pathogenic complex during all phases of wheat vegetation. Under the conditions of the year, the other two species - the pathogen of the disease:  Parastagonospora nodorum  and  Parastagonospora  avenae f. sp. triticea had no economic significance. The populations of the species  Zymoseptoria tritici , formed on winter and spring wheat cultivats according to morphological, physiological and pathogenic properties, were studied. It is shown that black corrugated colonies with an average growth rate and high sporulation predominate. Using monogenic lines, virulence phenotypes were determined in isolates taken from infectious wheat material. Seven virulence phenotypes were identified. All isolates hit the test lines from 2 to 4 points, therefore they were characterized by wide virulence and high aggressiveness. The information obtained is necessary for the development of a methodology for resistance breeding.
