摘　　要：对由国际水稻研究所提供的全球水稻分子育种亲本材料进行了稻瘟病和白叶枯病的抗性鉴定,其中有26份材料对供试的6个混合稻瘟病小种表现出高抗;有4份抗病材料2年白叶枯病抗性鉴定结果一致。筛选出3个双抗性较好的材料,可以用作水稻抗性育种的骨干亲本,为今后的进一步研究和应用打下了基础。The resistance of the materials from Global Rice Molecular Breeding Program to Blast and Bacterial Blight were identified in Yunnan province. The results indicated that 26 rice materials showed high resistance to the Blast. The resistance of four rice materials to the Bacterial Blight were assessed in different year after inoculation many strains. The result showed that some materials such as Feng-Ai-Zan、Zhong413、Yunhui290, have high resistance to the two diseases and could be used as main materials in rice breeding for disease resistance. It will provide a foundation for the further study and application in rice molecular breeding.
