Abstract：In this research，17 Phytophthora infestans isolates collected in Harbin in 2005, 2006 and 2008, and 46 isolates（all A1 mating type）collected from 8 sites of Heilongjiang Province in 2006 were used as experimental material. Clustering analyses were conducted on the relativity between P. infestans strains isolated in different years and from different geographical sources by 21 EST-SSR primer pairs, respectively. The results indicated that there was certain relativity between P. infestans strains collected in the same locality with the collecting year, and also there was certain relativity between P. infestans strains collected in the same year with geographical sources.
