摘    要:对长江中、下游湖北石首、江西九江、安徽芜湖三江段鲢、鳙、草鱼、青鱼天然群体共365尾鱼的线粒体DNA(mtDNA)的ND5/6、Cytb基因和D-Loop区片段进行了限制性内切酶酶切片段长度多态(RFLP)分析。结果表明:(1)长江中、下游鲢、鳙和青鱼的遗传多样性丰富,草鱼不甚丰富。发现鲢、鳙和青鱼的mtDNA基因型分别有28、19、27种,草鱼mtDNA基因型仅见7种;鲢、鳙和青鱼的基因型多样性

关 键 词:长江      草鱼  青鱼  DNA  多样性  线粒体

Abstract:Louis Bernatchez (Department of Biology, University Laval, Canada) RELP analysis of the mtDNA segment encompassing the ND5/6 and cytochromone b genes and D Loopregion was performed in Silver carp ( Hypophthalmichthys molitrix ), Bighead carp ( Aristichthys nobilis ), Grass carp ( Ctenopharyngodon idellus) and Black carp ( Mylopharyngodon piceus) from three sections (Shishou in Hubei Province, Jiujiang in Jiangxi Province, Wuhu in Anhui Province) along the middle and lower reaches of the Yangtze River. It was revealed that:(1) Silver carp, Bighead carp and Black carp showed a higher genetic diversity, whereas garss carp showed a lowergenetic diversity; The numbers of mtDNA haplotypes and the haplotype diversity indices for Silver carp, Bighead carp, Grass carp and Black carp were 28, 19, 27, 7 and 0 681, 0 583, 0 890 and 0 231 respectively. (2) The populations of Silver carp showed a significnat genetic diversity and a visible geographical distribution of genotypes; The populations of Bighead carp and Black carp had a significant genetic diversity but no visible geographical distribution of genotypes; The populations of Grass carp had neither significant genetic diversity nor visible geographical distribution of genotypes.
Keywords:Yangtze River  Silver carp  Bighead carp  Grass carp  Black carp  mtDNA  RFLP  Diversity
