Abstract:
Fifty-three strains of Phytophthora sojae have collected from eastern district of Heilongjiang from 2007 to 2008.Race1 1，13，17 and three pathotypes were identified with a set of international universal differential hosts(taking along with Gene Rps1a，Rps1b，Rps1c，Rps1d，Rps1k，Rps3a，Rps6 and Rps7，respectively).We found that the pathogenic bacteria can be divided into 4 virulence types and primarily ascertained the situation of virulence distribution.
