| 摘要: |
| 用37个SSR标记分析了新发现的琼海普通野生稻与三亚普通野生稻间的遗传关系。结果表明，SSR位点在三亚普通野生稻居群中的变异较其在琼海普通野生稻居群中的变异高。对琼海普通野生稻与三亚普通野生稻的聚类分析发现，两者在0.638 5处各聚为1类，由此可知，琼海普通野生稻和三亚普通野生稻之间具有较大的遗传分化。 |

| Genetic analysis on common wild rice Oryza rufipogon Griff.from Qionghai and Sanya by using SSR marker |

| Abstract: |
| The genetic relationship between common wild rices from Qionghai and Sanya in Hainan were studied by using 37 SSR markers. The result of the study showed that SSRs had more genetic variability in Sanya population than that in Qionghai. Based on cluster analysis,common wild rices in Qionghai and in Sanya were clustered together respectively at 0..638 5. These results showed that a litter more genetic differentiation existed between common wild rices in Qionghai and Sanlya. |
