玉米茎腐病研究进展

Advances in Studies of Maize Stalk Rot

茎腐病是国内外玉米生产中的重要病害之一,近年来,随着机械收获和籽粒直收,茎腐病已成为玉米生产中最具威胁性的病害,利用抗病品种是防治玉米茎腐病最为经济、有效的措施。因此,本文从茎腐病的发生与为害、病原菌种类、抗茎腐病种质资源筛选、抗性遗传和抗病基因发掘与定位等几个方面阐述了国内外玉米茎腐病的研究进展,旨在为该病害的综合治理奠定重要的理论基础。

Maize stalk rot is one of the important diseases,which are occurring in corn cultivating regions of China and abroad.Due to increasing mechanical harvesting and grain direct harvest,stalk rot has become the most threatening disease in maize production.The cultivation of resistant varieties is the most economic and effective measure to control stalk rot.This paper reviews the research progress of stalk rot on aspects of the distributing regions,pathogenic species,resistant germplasm screening,resistance inheritance and disease resistance gene discovery and localization,which will lay an important theoretical foundation for IPM of this disease.
