摘要:
近年来,随着耕作制度的改变和气候的变化,纹枯病在我国黄淮冬麦区和长江中下游冬麦区广泛发生,并呈逐年加重的趋势。为了筛选出可在生产或育种中利用的抗病材料,本试验对从国内外收集到的79份小麦材料及1份小麦近缘材料荆州黑麦,同时在温室和大田进行纹枯病抗性鉴定,结果表明,品种间存在纹枯病抗性差异,在小麦品种中进行小麦纹枯病抗源选择是有效的,温室和大田同时抗性表现较好的有14份材料:CI 12633、丽麦16、ARz、Cooker 983、FHB143、Italy 2、GUADALYPE、Ovontun、白火麦、山红麦、山农12号、小偃22、紫秆子和荆州黑麦,为纹枯病抗病育种提供稳定可靠的抗源。

Screening of Resistance to Sharp Eyespot in Wheat
Abstract:
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.
