Irrespective of rice cultivar, isolate BLS 93 had shorter incubation period and latest period, higher ooze production and longer lesions than avirulent isolate BLS 37. BLS 102 had an intermediate reaction. In all isolate-cultivar combination, ooze production was directly related to lesion length, with longer lesions producing more ooze. However, the resistant cultivar had less ooze and shorter lesions than the susceptible. Comparison of latest period, ooze production, and lesion length could be important factors contributing to variation in virulence of isolates or components of BLS resistance. The latent period and ooze productiion might be used to compare virulence of different isolates on the same cultivar
