Two-year trials indicated that the method ear inoculation by placing toothpick covered with fungus Fusarium graminearum into the silk channel 0.5-1 cm from the ear tip, proved to be the most effective for distinguishing resistant and susceptible genotypes to ear rot. Method of inoculation ear tip between husks using the syringe and ear inoculation by placing toothpick covered with fungus into the middle portion of the ear were too drastic for distinguishing resistant and susceptible genotypes. The method of ear inoculating into the leaf whorl did not appreciably differ from check, therefore as the check itself was not acceptable in breeding maize for resistance to ear rot.
