 In order to test the possibility of the presence of additional gene(s) other than previously identified ones in Japanese and Philippine differentials, a series of inoculation tests were carried out using seven Japanese standard isolates and 13 Philippine isolates. The purpose of the tests is to develop near-isogenic lines with monogenic base for establishing international differentials of rice bacterial leaf blight pathogen as well as to confirm the relationship of differentiation systems in Japan and in the Philippines.
 From the results obtained, it is possible that Japanese differentials, Chugoku 45 and Java 14, have additional gene(s) responsible for the resistance to the Philippine isolates. It is also possible that IRRI differentials (IR20, IR1545-339 and DV85) and two resistant cultivars (Zenith and Sateng) have additional gene(s). These cultivars should be analyzed genetically using Japanese and Philippine isolates to confirm the number of resistance genes.
 Kogyoku and Te-tep (Japanese differentials), and Cas 209 (IRRI differential) have no possibility of possessing an additional gene responsible for the resistance to Philippine or Japanese isolates.
 IR8 was considered to have an unknown resistance gene from its reaction to some Japanese isolates. This gene was found to be the same one as Xa-11.
 From the inoculation test using rice cultivars to seven Japanese and four Philippine bacterial groups, the existing host-parasite relationship reported by several researchers was reconfirmed.
