摘要
2012～2013年，应用田间人工接种的方法对目前辽宁省玉米生产中应用的55份玉米品种进行抗大斑病[Exserohilum turcicum （Pass．）Leonard et Suggs]鉴定与评价，筛选出对大斑病表现1级高抗（HR）的品种4份、3级抗病（R）的品种9份和5级中抗的品种16份。试验结果表明：辽宁省玉米生产上应用的玉米品种中，表现为中等抗病或感病品种占大多数，表现高抗的玉米品种较少。
During 2011 -2013, a total of 56 maize hybrids have been evaluated for resistance to Northern Corn Leaf Blight [ Exserohilum turcicum （Pass.）Leonard et Suggs ] by using an artificial inoculation in the field. Four highly resistant and nine resistant and sixteen moderately resistant hybrids were screened for the disease resistance. Amount of tested hybrids, most of them showed the moderately resistant or susceptible to Northern Corn Leaf Blight, and the highly resistant hybrids was very few.
