摘要
目的分析长白山越桔遗传多样性及其亲缘关系。方法用随机扩增多态DNA(RAPD)标记方法对1种野生越桔和2种不同的栽培越桔进行遗传多样性检测和遗传分析。结果采用40个随机引物共检测72个位点,其中多态位点27个,占37.5%;相似系数矩阵表明野生越桔和栽培越桔Ⅰ、栽培越桔Ⅱ的遗传距离分别为0.764和0.809;聚类图表明野生越桔和栽培越桔Ⅱ亲缘关系较近。结论长白山越桔的遗传多样性水平较低,野生越桔和栽培越桔之间的遗传变异不大,遗传因素在越桔形态变异上的作用小于环境因素。
Objective Analyzes genetic diversity and sibship of blueberry from the Changbai Mountain.Methods Genetic diversity examination and the genetic analysis to one kind of wild blueberry and two kind of different garden blueberry by random amplified polymorphic DNA(RAPD)marker.Results From the forty random primers 72 sites were detected,of which 27(37.5%)were polymorphism.The Proximity Matrix indicates Genetic Proximity Values between the wild blueberry and the garden blueberryⅠ,the garden blueberryⅡrespectively...
