白叶枯病是亚洲水稻生产上的一种重要病害。近十多年来,世界各稻米产国重点转入选育抗病品种的研究。在我国围绕品种抗病性,着重开展病原菌系类型、地域分布及其致病力变异,抗性资源鉴定评价和利用以及杂交育种等研究,已取得了成效;对曾一度严重威胁杂交稻的凋萎型白叶枯病,也重点进行了研究、防治,有效地控制其蔓延扩展;长期以来,对争论较多的侵染源问题,通过进一步探索,也提出了一些新的见解。本文就1975年以来国内对稻白叶枯病研究的进展作一概述。一、病原菌系研究查清各地病原菌系的类型及分布,选择优势菌群代表菌株,进行抗性鉴定,并不断监测品种抗病性的丧失与病原菌的变异分化问题,
Bacterial blight is an important disease in Asian rice production. In the past ten years or more, the countries producing rice in the world have shifted their focus to the study of breeding resistant varieties. In our country, the disease resistance has been focused on the types of pathogenic bacteria, geographical distribution and variation of pathogenicity, evaluation and utilization of resistant resources and hybrid breeding and other research, and has achieved success; on the serious threat to hybrid rice Verticillium wilt disease, but also focus on research, prevention and control, effectively control its spread of expansion; For a long time, more controversial sources of infection, through further exploration, but also put forward some new ideas. This article gives an overview of the progress of research on rice bacterial leaf blight in China since 1975. First, the pathogen research to identify the types and distribution of pathogenic bacteria around, select the dominant strains of bacteria, identification of resistance, and continue to monitor the loss of varieties of disease resistance and pathogen differentiation and differentiation problems,
