Abstract:
　 By using American soybean hosts(Harosoy ,Harosoy63,Sanga, Mack, PI171142,Aitona)of Phys-iological Races of phytophthora megasperma , 120 strains were identified ,which came from six soybean eco-regions of Heilongjiang Province .Among them 40strains had been purified .The results showed 7 raceswere identified, they were race -1, race -3 ,race -9, race -11 ,race -17 , race -21, race -24.The distribu-tion frequency of race -1 was 60 %, of race -3,race -11 and race -17 together were 15%, and of race -9,race -21 and race-24 together were 5%.
