近几十年来，由于栽培方式和气候的变化，长江中下游和黄淮冬麦区小麦纹枯病日益严重。为了获得小麦生产和育种中使用的抗纹枯病种质资源，对中国等80份材料进行了田间和大棚抗纹枯病鉴定。结果表明，所选材料间差异显著，抗源有效。筛选出大田和温室均表现抗纹枯病的材料14份，分别为CI 12633、力麦16、ARZ、Cooker 983、FHB 143、意大利-2GUADALYPE、Ovontun、白火麦、荆州黑麦、陕红麦、山农12、小研22、紫甘子等材料用于抗纹枯病亲本等抗病育种。
During last decades,wheat sharp eyespot has become more severe in the middle and low Yangtze River and Huang-huai winter wheat region due to the change of the cultivation methods and climate.To obtain some germplasms with resistance to sharp eyespot used in wheat production and breeding,80 materials from China and other countries were evaluated for the resistance to sharp eye spot in field and greenhouse.The results indicated that there were significant differences among selected materials,and the resistant sources were efficient.Fourteen materials with resistance to sharp eyespot both in field and greenhouse,were screened,i.e.,CI 12633,Limai 16,ARz,Cooker 983,FHB 143,Italy-2,GUADALYPE,Ovontun,Baihuomai,Jingzhouheimai,Shanhongmai,Shannong 12,Xiaoyan 22,and Ziganzi.These materials were used in breeding of resistance to sharp eyespot such as resistance parents.
