Abstract
Ninety isolates collected from five different provinces and cities (Hebei, Yunan, Sichuan,Chongqing, Inner Mongolia ) during 1997 -1998 were tested with potato clones possessed 8 dominant mono-genes R1, R3, R4, R6, R7, R9, R10, R11 and the combination of R1-R4 of the international late blight dif-ferential host. It concluded that: (1) in the 90 isolates tested 21 different races were detected, of which the 1.3. 4. 7. 9. 10. 11 was very common with frequency of 32.2%, followed by 1. 3. 4. 6. 7. 9. 10. 11 and 3.4. 7. 9. 11 with frequency of 10.0%; (2) all tested resistant genes were compatible to the virulent gene of iso-lates of Phytophthora infestans assayed, which indicated that the virulent genes were very common in thetested population of Phytophthora infestans.关键词
