摘　　要：采用人工接种和自然发病鉴定方法,评价了238份特用玉米杂交种对矮花叶病和211份特用玉米对粗缩病的抗病性。结果表明,高抗矮花叶病占41.0%,抗病占18.1%,中抗占19.3%;高抗粗缩病占10.4%,抗病占26.5%,中抗占26.9%。在不同区试类型品种中,高油玉米抗病性较强,达到中抗以上分别占93.3%和66.7%;糯玉米占78.3%和63.6%;青贮玉米占83.8%和47.7%;甜玉米对这2种病害抗性较差,分别占55.8%和46.5%。通过审定的30个品种中有17个品种兼抗这2种病害。Based on artificial inoculation and natural incidence, the resistances to virus diseases of 238 particular maize hybrids were identified and evaluated. The results of Maize Dwarf Mosaic showed that 41.0%, 18. 1%, 19. 3% and results of Maize Rough Dwarf showed that 10.4% ,26.5% ,26.9%. The resistances to Maize Dwarf Mosaic and Maize Rough Dwarf varied significantly with different type hybrids. Among maize hybrids, the percenta- ges of higher than moderate resistance hybrids were 93.3% ,66.7% ;waxy maize accounted for 78.3% ,63.6% ;si- lage maize accounted for 83.8% ,47.7% respectively;Sweet corn accounted for 55.8% and 46.5%. Seventeen of thirty certificated particular maize varieties showed moderate resistance of two virus diseases.
