| 中文摘要: |
| 为了更好地利用我国小麦种质资源和丰富小麦抗白粉病基因库，利用4个不同来源和毒力的小麦白粉菌株对六个小麦生产品种（武都白茧、天选45、周98165、偃展4110、中梁9589和中麦629）进行苗期抗白粉病基因的遗传分析。结果表明，武都白茧对菌株MX20的抗性由1对隐性基因控制；天选45对菌株HY5的抗性由1对隐性基因控制；周98165对菌株HX4的抗性由1对显性基因控制；偃展4110对菌株HX4的抗性由1对显性基因控制；中梁9589对菌株HY5的抗性由2对隐性基因独立作用控制；中麦629对菌株CCQ15的抗性由2对隐性基因独立作用控制。 |

| To make better use of wheat germplasm and enrich wheat powdery mildew resistant gene pool,four strains with different sources and virulence were used to identify F1 and F2 generations derived from six commercial wheat cultivars Wudubaijian,Tianxuan 45,Zhou 98165,Yanzhan 4110,Zhongliang 9589 and Zhongmai 629 crossed with susceptible wheat cultivar Mingxian 169 at the seedling stage under controlled greenhouse conditions.The genetic analysis results showed that the resistance of Wudubaijian to MX20 and that of Tianxuan 45 to HY5 was controlled by one recessive gene,respectively; the resistance of Zhou 98165 and Yanzhan 4110 to HX4 was controlled by one dominant gene,respectively; and the resistance of Zhongliang 9589 to HY5 and that of Zhongmai 629 to CCQ15 was controlled by two recessive genes,respectively. |
