| 摘 要： | 大豆品种早熟18是抗疫霉根腐病的有效抗源。本研究鉴定和分子标记早熟18的抗疫霉根腐病基因，以期为该品种的有效利用及分子辅助育种奠定基础。以感病大豆品种Williams与早熟18杂交建立分离群体。抗性遗传分析表明，早熟18对大豆疫霉菌抗性由1个显性单基因控制，该基因被定名为RpsZS18。SSR标记连锁分析表明，RpsZS18位于大豆分子遗传连锁群D1b上的SSR标记Sat_069和Sat_183之间，与这两个标记的遗传距离分别为10．0cM和8．3cM。RpsZS18是D1b连锁群上鉴定的第一个抗疫霉根腐病基因。 |

| Abstract: | Soybean cv.Zaoshu 18 had been identified as an effective source resistant to Phytophthora root rot of soybean.The objectives of this study were to identify and map the Phytophthora resistance gene in Zaoshu 18 in order to facilitate its utilization and marker-assisted breeding.Zaoshu 18 was crossed with susceptible cultivar Williams to develop mapping populations.Genetic analysis of F_2 and F_(2:3) progenies indicated that resistance to Phytophthora sojae in Zaoshu 18 was controlled by a dominant single gen... |
