| 摘 要： | 我国玉米上发生的病害约30余种,引起病害的病原有真菌、细菌病毒和线虫等50余种.发生普遍危害严重的病害有大斑病、小斑病、丝黑穗病、青枯病、穗粒腐病、纹枯病、全蚀病、矮花叶病等.每年因各种病害造成玉米产量损失达10%.本文简要的论述了国内外对玉米品种的抗病性与病菌致病性的相互作用的最新研究概况.为掌握病菌的变异规律与今后应采取的选育抗病品种的策略和方法,提供了科学的信息及理论依据.

| Abstract: | About thirty corn diseases have been described in China. These diseases are caused by more than fifty pathogens of fungi,bacteria,viruses and nematodes. The most wide spreading and serious diseases include northern leaf blight, southern leaf blight,head smut, stalk rot,ear rot, rhizoctonia sheath spot, take all, dwarf mosaic virus etc. These various diseases may cause corn yield losses by some 10% in each year. The new researching advancement of the correlation of corn resistance and pathogenicity of the pathogens is discussed in this paper. It also provides scientific information and theoretic foundations so as to know well the variation patterns of the pathogens and the programme for the resistant cultivar selection in future. |
