Four hundred and seventeen single-uredinial isolates of Puccinia triticina collected from wheat in seven regions of Russia in 2007 were tested for virulence with 24 near-isogenic wheat differential lines and molecular variation with six RAPD and one UP-PCR DNA markers. Seventy-nine virulence phenotypes and 71 molecular genotypes were identified. The P. triticina isolates varied for virulence on resistance genes Lr1, Lr2a, Lr2b, Lr2, Lr3a, Lr3bg, Lr3ka, Lr14a, Lr14b, Lr15, Lr16, Lr17, Lr18, Lr19, Lr20, Lr21, Lr24, Lr26, Lr28 and LrB. All isolates were virulent on Lr10, Lr11 and Lr30, and avirulent on Lr9. THTTTJ was the predominant phenotype in all regions with frequency ranging from 25 to 63%. Diversity analysis of the regional collections demonstrated inconsistency of results obtained with virulence and molecular markers. According to the virulence data, the North Caucasian and Central collections of P. triticina were the most distant from all the other regional populations. The most similar were collections from West Siberian and Ural regions, which may be a result of growing genetically similar wheat cultivars. According to the molecular marker data, the Central, Central Black Earth, and Ural populations clustered distinctly from the North Western, North Caucasian, and West Siberian collections.
