| 摘 要： | 小偃麦山农87074-557是小麦一长穗偃麦草双体异代换系,它保留了偃麦草的许多优良特性,是小麦抗病育种和遗传改良的基础材料.本文利用接种鉴定法对山农87074-557的抗病性进行鉴定表明:其对白粉病和条锈病均表现免疫,其抗性基因来源于长穗偃麦草,且其白粉病和条锈病抗性均分别受1对显性基因控制.在592对小麦SSR引物中寻找到1个标记Xgwm344120/150与白粉病抗性基因和条锈病抗性基因连锁,推测白粉病抗性基因可能为新基因,条锈病抗性基因可能不同于已定位的抗小麦条锈病基因.

| Abstract: | Tritielytrigia Shannong87074-557, derived from the hybridization between wheat and decaploid Elytrigia elongata, is an alien disomic addition line. For its many useful traits originated from Elytrigia, Shannong87074-557 is a basic material for wheat disease resistance breeding and genetic improvement. In the presentation, the inoculation identification was employed test the disease resistance of Shannong87074-557. The results showed that Shannong87074-557 was immune to powdery mildew and yellow rust, its di... |
