摘要: 利用SSR 分子标记对羽叶金合欢( Acacia pennata) 的野生种和栽培种进行了分析, 利用改良的CTAB方法优化了其总DNA 的提取方法, 并优化了PCR 扩增条件。从已有的金合欢属植物的82 对SSR 引物中筛选出多态性高, 稳定性好的12 对引物作为羽叶金合欢的SSR 分析引物, 为进一步对其进行遗传多样性研
究提供了依据。

关键词: 羽叶金合欢, DNA 提取, SSR 引物筛选

Abstract: The total DNA of wild Acacia pennata and cultivated variety were analyzed using SSR markers . We improved CTAB DNA isolation method and PCR amplified conditions . 12 primers were screened from 82 primers existing in Acacia genus, which had high polymorphism and stability. The results provided references for genetic diversity research of Acacia pennata using SSR marker.

Key words: Acacia pennata
