摘　　要：本研究首次探讨了中国23个小麦条锈菌鉴别寄主抗条锈基因状况。推导出Trigo Eureka、阿夫、丹麦1号和水源11分別含有抗条锈基因YrBastion、YrA、Yr3和YrSu,洛夫林10和洛夫林13含有Yr9,碧蚂1号,抗引655、西北54、北京8号含有Yrl。证实了其中14个品种含有目前国际上所未知的抗条锈基因。本文讨论了不同抗病基因分析方法的优缺点,对今后如何进一步开展这一方面的研究提出了看法。The component varieties of Chinese differential hosts for wheatstripe rust are totally different from those of the European and theworld sets.The resistance genes of the Chinese differentials are firstlypostulated.It is shown that Trigo Eureka,Funo,Danish 1 and Suwon 11possess Yr Bastion,Yr A,Yr 3 and Yr Su respectively;Lovrin 10 andLovrin 13 possess Yr 9;Bima 1,Kangyin 655,Xibei 54 and Beijing 8possess Yr 1.14 of the differentials are conformed possessing resistancegenes which are unknown in the world so far.It seems that most ofthe designated Yr genes are not in these differential hosts.The meritsand demerits of different approaches for gene analysis are discussed.
