Physiological Races of Phytophthora infestans in Korea

다국어 초록 (Multilingual Abstract)

A total of the 261 Phytophthora infestans isolates
collected from 2003 to 2005 in Korea were investigated
for their physiological race composition. Among the
isolates, we detected 18 physiological races and the
dominant races were R0.1.3.5.6.10.11 and R0.1.3.5.6.7.
10.11 with frequencies of 18.4% and 11.4%, respectively.
All of the P. infestans races carried multiple virulence
genes and showed virulence to the potato resistance
genes R1, R3, R5, R6, R7, R10 and R11, but not to R8
and R9. Therefore, it is likely that the physiological
races of P. infestans were diverse in Korea.
