| 中文摘要: |
| 为了解甘啤系列啤酒大麦品种（系）与国外引进品种间的遗传关系，利用SSR标记技术对10个甘啤系列啤酒大麦品种（系）和25个国外引进品种的遗传背景进行了遗传多样性分析。结果表明，所用49对SSR引物中，有32对有多态性。这些品种遗传相似系数（GS）的分布范围较小，处于0.0500~0.6667之间。通过聚类分析，在GS值为0.26的水平上，这些品种被聚为4大类，大多数甘啤系列品种（系）分在同一类中，表明其遗传距离较近，遗传基础较狭窄；国外引进品种的分布范围相对较宽，表明其遗传基础较广泛。 |
| 英文摘要: |
| The genetic relationship among 35 beer barley varieties, including 10 Gansu and 25 foreign varieties were investigated by SSR. The results showed that among the 49 pairs of SSR primers used, 32 pairs of SSR primers detected polymorphisms. Clustering analysis showed that the range of between genetic similarity coefficient (GS) located in between 0.0500~0.6667. At the level of 0.26 GS, these varieties could be clustered into 4 groups, the majority of Ganpi series varieties (lines) were located in the same group, indicated that the genetic basis was rather narrow. The imported varieties had relatively wide range, indicated that their genetic basis is more extensive. |
