- Аннотация: Phytophthora infestans isolates were collected in the VIR potato plots (Pushkin, St. Petersburg) and in commercial potato stands in several provinces of the European Russia, from Leningrad in the west to Sverdlovsk in the east. Simple sequence repeat (SSR) patterns of these isolates and of monozoospore lines obtained from the Pushkin isolates definitely differed from the SSR profiles reported for P. infestans lineages in Western and Central Europe. The analysis of monozoospore lines suggested that the different pathogen strains cohabit one and the same potato leaf. We failed to relate SSR patterns of these strains to plant late blight resistance and the profiles of resistance genes (R genes) revealed with specific sequence characterized amplification region. SSR patterns of P. infestans genotypes poorly matched the variations in their mating type and such indices of potential and actual pathogenicity as the profiles of virulence factors assessed with the plant differentials, avirulence gene patterns and aggressiveness in the tuber test.
