Leaves of rice variety Sasanishiki were previously inoculated with virulent race N-1 of rice blast fungus but were reinoculated with avirulent race C-3, pathogenic to variety Fukei 69 or Tachihonami after development of susceptible lesions.
Abstract
Leaves of rice variety Sasanishiki were previously inoculated with virulent race N-1 of rice blast fungus. After development of susceptible lesions, the infected leaves of Sasanishiki were reinoculated with avirulent race C-3. Conidia produced on the lesions contained a few conidia of race C-3 pathogenic to variety Fukei 69 or Tachihonami.
