Abstract: The pathogen fusarium moniliforme was Isolated with conventional tissue separation method.Maize was bred under natural environment.Inoculation was done using the method of double toothpick when the flowers were wilting.Investigation of morbidity was done after the maize were ripe and determining the resistance according to the evaluation standard of resistance. The results showed there was one variety that shows high resistance and account for 1.8% of total materials;there were 40 varieties that show resistance and account for 72.7% of total materials;there were 13 varieties that show sensibility and account for 23.7% of total materials;there was one variety that shows high sensibility and account for 1.8% of total materials. The experiment screen out 41 varieties that can be used as the resources against Ear and Kernal Rot of maize.It also provides the scientific basis for the selecting varieties of maize production in Shanxi province.
