Reaction of maize hybrids to ear rot caused by Fusarium graminearum Schwabe

Abstract

Ear rot caused by Fusarium graminearum Schwabe (teleomorph stage: Gibberella zeae (Schwein.) Petch) is a destructive disease of maize. In our experiment we tested twenty maize hybrids. Two inoculation techniques differing in the way of application of a macro-conidial suspension, were evaluated for their effectiveness in assessing maize resistance to ear rot. Based on the results of one season, highly significant differences in sensitivity to Fusarium ear rot between genotypes for all variants under mist irrigation and without mist irrigation, were detected.
