Abstract
When the cultivars Mokoto, Sasanishiki and Toyonishiki, differing in field resistance to blast, were inoculated with mixtures of strs. of P. oryzae resistant to kasugamycin and/or IBP, no difference was observed between the cultivars regarding the isolation frequency of fungicide-resistant strs.
