摘　　要：东北水稻种植区是我国粳稻的主产区,长期以来稻瘟病是生产中危害最严重的病害之一。本研究就近30年来东北稻区稻瘟病菌优势种群和优势小种变迁,主栽品种抗性进行了综述,分析了已鉴定的稻瘟病抗性基因在东北稻区的利用价值,同时对该地区稻瘟病研究存在的问题与今后的研究方向进行了讨论,以期为水稻抗稻瘟病的育种提供参考。Rice blast has an important economic impact during the past many years,causing significant yield losses in the northeastern rice growing region,where japonica cultivars have been widely planted.We have surveyed the predominant population and race changing of Magnaporthe oryzae,and the resistance of rice cultivars during the last 30 years.Moreover,the utilization values of the identified resistance genes,and the key research aspects in the future were also discussed.These results will supply some suggestion for the further research about effectively controlling rice blast in this region.
