摘要/Abstract

摘要： 根据对16个国外和4个国内已知毒性基因的小麦条锈菌反应，结合系谱分析，研究了39个陕西、甘肃、四川省重要小麦品种所具有抗条锈基因。试验结果显示，已知抗病基因Yr1、2、3、7、9、10、SD、Su等分布在20个品种中，其中11个品种含有Yr9。3个品种对供试菌系均表现抗病反应，2个品种抵抗大多数供试菌系，表明它们具有主效的未

Abstract: The presence of genes for resistance to stripe rust (Puccinia striiformis) was studied in 39 wheat cultivars from Shananxi, Gansu and Sichuan provinces hased on determining their reactions to 16 alien and 4 Chinese strains with different virulent genes and analyzing their pedigrees. Only 8 known gen
