Puccinia triticina isolates from North Caucasus and Leningrad region were compared in regard to the genetic structure, phenotypic composition as well as frequency of occurrence of RAPD-phenotypes and polymorphous major fragments with the help of Rogers index. Did not demonstrate any significant differences according to their genetic structure and occurrence of major fragments of DNA-polymorphism. The difference of isolates from given regions was determined with high degree of confidence according to the phenotypes of virulence and RAPD-phenotypes
