摘要
采用AFLP分子标记技术,利用筛选出6对多态性较强的引物组合,构建了白花蛇舌草25份种质的AFLP指纹图谱.6对引物组合共扩增出888条谱带,其中多态带661条,占73%.聚类分析结果表明,来源地相同的白花蛇舌草居群多表现出较为密切的亲缘关系,不同来源地的白花蛇舌草居群间遗传差异相对较大,其中海南白花蛇舌草独自呈类,与其它省份的亲缘关系较远.
AFLP fingerprints of Hedyotis diffusa were established by AFLP technique and six primer pairs.There were 888 bands,of which 661 were polymorphic,accounting for 73%.The cluster analysis indicates： most of the population in the same area have the closer relationship,the heredity difference of the population from different areas is relatively big.And the population from Hainan being a kind alone is far with other population in relationship.
