Abstract

The structure of P. triticina populations collected in Northwest region of Russian Federation in 2007 was studied by virulence and DNA-markers. 35 virulence phenotypes and 37 DNA-phenotypes were detected among 139 isolates. It was determined that virulence diversity was much higher within the samples from Pskov and Leningrad populations collected on State Cultivar Testing Stations than within the group of isolates sampled from commercial fields in Novgorod region. Comparative virulence analysis revealed significant differences of Pskov population vs. Novgorod and Leningrad ones. Analysis with the molecular markers established similar level of diversity within all three populations, and did not reveal significant differences between the populations. No correlation between results obtained by virulence and molecular marker analyses was observed. Similarity of molecular marker profiles of isolates collected in the North-West Russia might be an evidence of their common genetic origin.
