摘要： 用13个条锈菌生理小种接种,冬小麦丰抗13抗40E8、104E9、108E9、108E141、171E138和109E9等生理小种。应用单体遗传分析确定丰抗13可能具有3个抗条锈病基因。在对生理小种108E141的抗性上,丰抗13同中国春有一对基因的差异,抗病性为显性,该基因位于染色体2A 上。抗该生理小种的基因也抗40E8、104E9和108E9。已知位于2A 上的抗

Abstract: The Chinese winter wheat variety Feng-Kang 13 showed resistance tosix British physiologic races of P.striiformis 40E8,104E9,108E9,108E141,171E138 and 109E9 when 13 yellow rust races of P.striiformis were inocu-lated separately at seedling stage.At least two genes for yellow rust re-sistance have bee
