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.
