| 摘 要： | 利用随机扩增多态性DNA标记(RAPD)技术对61份花椰菜品种进行了遗传多样性分析。从200个随机引物中筛选出10个引物,10个引物扩增的总位点数为69个,多态性位点数为44个,多态性达63.77%。UPGMA聚类分析揭示了各品种间的亲缘关系。RAPD标记说明花椰菜品种间有相同的遗传背景,但相互之间又存在一定差异。

| Abstract: | Random amplified polymorphic DNA(RAPD) was applied to detect the genetic diversity of 61 cauliflower samples.Ten RAPD primers produced 69 bands,of which 44 bands were polymorphic and accounted for 63.77% of the total bands.UPGMA clustering analysis displayed the genetic relationships among the varieties.RAPD markers indicated that,although cauliflower varieties had the same genetic background,there were certain differences among them. |
