| 摘 要： | 利用SSR分子标记分析了58份籼稻材料间的多态性,计算了各材料间的遗传距离,并以遗传距离为依据,通过UPGMA法聚类分析,把供试的籼稻材料划分为3个类群。杂种优势分析表明,群间优势大于群内优势,说明利用SSR标记划分籼型水稻杂种优势群是可行的。 |
| 关 键 词： | SSR标记 籼稻 杂种优势群 遗传距离 |

| Abstract: | The polymorphisms of 58 varieties in indica rice were analyzed by using SSR markers,and the genetic distance(GD) of them was assayed.By cluster analysis with UPGMA method,the tested varieties could be divided into three groups based on GD between them.The heterosis analysis showed that the inter-group heterosis was greater than the intra-group heterosis,which indicates the feasibility of dividing rice heterotic groups by using SSR markers. |
| Keywords: | SSR marker indica rice heterotic group genetic distance |
