Resistance in susceptible maize to Helminthosporium carbonum race 1 induced by prior inoculation with race 2

1990-11-01

Abstract excerpt

Inoculation of leaves of susceptible maize genotypes with the nonpathogenic race 2 of Helminthosporium carbonum at least 10 hr before inoculation with the pathogenic race 1 prevented development of large lesions typical of the susceptible reaction. Appressorium formation, penetration, and hyphal growth by the pathogen were decreased. Addition of HC-toxin (the host-specific toxin produced by pathogenic race 1) to t...
