Abstract:
Thirty samples of soybean Cercosporidium sojinum were collected from 17 soybean production area in Heilongjiang Province in 2007，and a set of 6 differential cultivars were used to identify the physiological race types and the emergence rates in different areas.Seven physiological races of race 1，4，6，7，8，11，and 4 unknown physiological races were identified.The results indicated that race 1 was the dominant race with frequency of 39%，reduced 9%.The second one was race 7 with frequency of 28%，increased 7% compared with 2006.Based on the identification of main varieties in Heilongjiang province，four high resistance varieties of Kenfeng 16，Kenfeng 18，Suinong 22 and Suinong 25，and 14 resistance varieties were identified.
