Although 19 bacterial blight resistance genes have been identified so far (Kinoshita 1991), precise information on their compatibility or incompatibility with local pathogen populations is essential for designing breeding programs for resistant varieties. We evaluated the effectiveness of known bacterial blight  resistance genes singly and in combination under field conditions against local populations of the pathogen in a trap nursery under irrigated conditions during the 1998 wet season.
