摘要

The article analyzes our own data and data from the literature on the study of plant-pathogen interactions in the pathosystem of Puccinia triticina and host plants of the genera Triticum and Aegilops with different ploidy and genomes. We characterize the long-term variability of the Russian populations of the pathogen, caused by the cultivation of genetically protected cultivars of common wheat (T. aestivum). Differences of the pathogen's virulence on hexaploid species T. aestivum and tetraploid wheat (T. durum) are shown. Data on the pathogen's virulence on other hexaploid, tetraploid, and diploid relative species Triticum sp. and Aegilops sp. are presented. Adaptation and specificity to the host plant were shown as the key driving factors in the evolution and divergence of clonally propagating phytopathogens, which include leaf rust.
