| 摘 要： | 利用徽卫星分子标记研究鄱阳湖15个日本沼虾(Macrobrachium nipponense野生群体的遗传多样性.结果表明:10个微卫星位点呈高度多态性,共检测到129个多态性位点；每个群体中至少有5个位点显著偏离Hardy-Weinberg平衡,表现出杂合不足；15个日本沼虾群体均表现出较高的遗传多样性,其中大坝外群体和星池群体遗传多样性较高,万户和湖口群体相对较低.瓶颈效应和突变-漂移平衡分析表明,鄱阳湖日本沼虾群体近期没有经历过瓶颈效应,群体数量也没有下降.群体间F统计量及AMOVA分析显示,鄱阳湖日本沼虾群体存在极显著的遗传分化程度(FST=0.04709,P＜O.01).综上所述,鄱阳湖日本沼虾群体具有丰富的遗传多样性,可作为日本沼虾选育的基础群.

| Abstract: | By the method of microsatellite analysis,an investigation was conducted on the genetic diversity of 15 wild populations of oriental river prawn(Macrobrachium nipponense) in Poyang Lake.The 10 microsatellite loci were highly polymorphic,and a total of 129 alleles were detected.The tests of departure from Hardy-Weinberg equilibrium indicated that at least 5 loci for each population were in significant heterozygosity deficiency.For all the populations,there existed significant deviation from Hardy-Weinberg equ... |
