The pathogenic races of 450 cultures of Xanthomonas oryzae pv. oryzae, isolated from eight locations in the inland mountainous area of Hiroshima Prefecture during 2000 to 2003, were determined with a set of Japanese differentials. The rice cultivars infected with the bacterium are thought to be in the Kinmaze group, which does not have any resistance genes. Five Japanese races IA, IB, II, V, and VII occurred across the area, although the composition of the races in each location altered during the surveyed 4 years.
