玉米茎腐(青枯)病研究进展

Research Progress of Maize Stalk Rot Disease

玉米茎腐(青枯)病不仅在我国广泛发生,也是世界性的玉米病害,严重影响全球玉米的总产量以及种子品质。简要概述了该病的发生与危害,致病菌及发病成因和相应栽培措施;通过对已有的玉米抗病鉴定方法及病原菌鉴定方法总结分析,认为抗病育种与抗性鉴定之间存在一定的关联不够问题;着重介绍了玉米种质资源的筛选,玉米对茎腐(青枯)病抗性遗传规律和分子生物学领域的研究进展;并且对玉米茎腐(青枯)病的研究方向提出了一些参考建议。

Maize stalk rot is not only widespread in China,but also a worldwide disease,which seriously affects the yield and quality of maize.Its distribution and loses caused by the disease,its pathogenic microorganisms and their identification and the evaluation for resistant germplasm resources are briefly discussed.It is indicated that the linkage between the resistance evaluation and breeding is not sufficiently close.The research progresses in genetic regulation and molecular biology of the disease resistance in maize are introduced,and some reference suggestions for further research are put forward.
