| 摘 要： | 利用基因推导法和分子标记对我国主要麦区的小麦品种(系)进行了抗白粉病基因的鉴定。结果表明,南30-10等15个品种(系)含有Pm8,新麦2号等9个品种(系)含有Pm4,中植4号等9个品种(系)含有Pm21,郑麦113含有Pm4b+5b,杨09-111和新紫1号含有Pm2+mld。研究发现,基因推导和分子标记相结合,可大大提高小麦品种(系)抗白粉病基因鉴定结果的准确性,鉴定结果可为抗病育种和品种布局及白粉病的防治提供依据。 |

| Abstract: | Powdery mildew resistance genes in wheat cultivars (lines) from major Chinese wheat regions were studied by using gene postulation and molecular markers. The results indicated that Pm8 was the most postulated or detected genes carried by fifteen cultivars (lines). Pm4 presented in nine cultivars (lines). Pm21 presented in nine cultivars (lines). Zhengmai113 was postulated to possess Pm4b+5b. Yang 09-111 and Xinzi No.1 was postulated to possess Pm2+mld . The results showed that the combination of gene postulation and molecular markers can greatly improve the accuracy of the identification to powdery mildew resistance gene in wheat cultivars (lines). The identification results can provide the basis for disease resistance breeding, cultivar deployment the prevention and control of powdery mildew. |
