引言在 Sears 将叶锈抗性由小伞山羊草(Aegilops umbellutata)转移到普通小麦的经典工作以后,一些研究者已经成功地将异属抗病基因加入到六倍体小麦中去。虽然一些研究者在硬粒小麦上已发现异属的附加系,但还没有关于异属基因转移到四倍体小麦上的报道。如果能诱发这种转移,在野生的和栽培的小麦亲缘中这种有用的抗锈基因对硬粒小麦育种将是很有价值的。在本研究中,将抗秆锈的基因由长穗偃麦草(Agropyrn elongatum)和黑 INTRODUCTION Following the classic work of Sears on the transfer of leaf rust resistance from Aegilops umbellutata to common wheat, some researchers have successfully introduced heterologous resistance genes into hexaploid wheat. Although some researchers have identified heterologous lines on Durum, there has been no report of heterologous gene transfer to tetraploid wheat. If this transfer can be induced, this useful rust-resistance gene in wild and cultivated wheat relatives would be valuable for durum wheat breeding. In this study, the genes for resistance to stalk rust were composed of Agropyrn elongatum and black
