摘要： 1997~1999年对204份参加河北省和国家黄淮海区域试验的玉米杂交种，进行了1428份次玉米大、小斑病、矮花叶病、茎腐病、黑粉病、眼斑病人工接种鉴定和玉米粗缩病的病区自然发病鉴定。鉴定出能兼抗4种以上玉米病害的杂交种有户单961、承玉5号、郑94-2、邯95-4、衡单10号、遵单1号、遵单3号、中原单32、邢抗2号、冀玉8号、石97-1等11份，占所鉴定材料的5.4%。

Abstract: From1997-1999, 204 corn hybrids which have been selected to join Hebei provincial and National Huanghuaihai zone testing were used to evaluate their resistance to Southern Leaf Blight, Northern Leaf blight, Maize Dwarf Mosaic, Smuts, Satlk Rot and Curvularia Leaf Spots by using artificial inoculation method and to Maize Rough Dwarf in the field. The result showed that11 corn hybrids, which account for5.4% of all the tested hybrids, can resist more than4 diseases. They are Hudan961, Chengyu5, Zheng94-2, Han95-4, Hengdan10, Zundan1, Zundan3, Zhongyuandan32, Xingkang2, Jiyu8, and Shi97-1.
