Abstract:During recent years, stalk rot and head smut have becoming two of the major diseases for the maize production in China. It was turned out that the disease-resistant breeding was the most effective approach to resolve the disease problem by the discovery and application of newly resistant germplasm. In this study, a set of resistant germplasm from introduced U.S. GEM materials for stalk rot and head smut were identified and selected under the condition of repeated inoculation, which was meaningful to the enhancement of disease-resistant maize germplasm of China.
