| 摘 要： | 籼稻地谷是我国杂效裟育种上重要的稻瘟病抗源之一。利用我国稻区的稻瘟病菌系ＺＢ１３和ＺＢ１５对地谷与感病品种江南香糯的杂效Ｆ１、Ｆ２和Ｂ１Ｆ１群体，以及地谷与感病品种丽江新团黑谷、冈４６Ｂ和８９８７的Ｆ２群体进行接种鉴定，根据抗病性的分离确认地谷对ＺＢ１３和ＺＢ１５的抗性受显性基因控制。利用菌系ＺＢ１３接种地谷和１０个具有已知抗病基因的鉴别品种及其杂交Ｆ１和Ｆ２群体，进一步证明了地谷的抗温性受１对显 |

| Abstract: | Digu is one of the important genetic resources in rice breeding for resistance to blast disease in China. In this study, the disease resistance identification in the parental varieties and the population F1, F2 and B1F1 from the crosses involving Digu and four susceptible varieties was carried out by inoculation with two Chinese blast strains, ZB13, and ZB15. The results demonstrated that Digu had one dominant gene Pi-d(t) to ZB13, which had been reported by Li SG .The F2 populations of Digu and other ten different varieties with known resistance genes were inoculated with strains ZB13 and the results further demonstrated that blast resistance of Digu to strain ZB13 was controlled by one dominant resistance gene. |
