| 摘 要： | 用"中国春"单体系和抗锈品种"丰抗2号"杂交,对其抗病基因进行染色体定位。结果表明,丰抗2号对条锈菌小种25号的单显性抗病基因位于5B染色体上;对叶锈菌小种38号的单显性抗病基因位于5A染色体上。位于5B和5A染色体上的两个分别抵抗条锈和叶锈病的基因可能是新的抗病基因。

| Abstract: | A set of 21 monosomics of Chinese Spring wheat was used to locate the rust resistance genes of Fengkang 2, developed by the Chinese Academy of Agricultural Sciences. The resistance to yellow rust race CY25 was controlled by a dominant gene located on chromosome 5B and resistance to leaf rust race CL38 was controlled by a dominant gene located on chromosome 5A in Fengkang 2. Most likely these two genes are new. Its reliability, high yielding potential and effective disease resistance have made Fengkang 2 an attractive cul-tiver to both farmers and breeders for a relatively long periodin winter wheat areas of China. |
