Mitochondrial DNA analysis of the blunt-snouted and sharp-snouted lenoks of the sympatric zone (Amur basin) and blunt-snouted lenok of two allopartic populations (North-Eastern and Southern Primorye) as well as taimen was carried out with 12 restriction endonucleases. Nine mtDNA clones were resolved: in fours for each form of lenok and one for taimen. Estimation of the average percent of nucleotide differences of mtDNA (tau) obtained for one sample of sharp-snouted lenok was 0.51 + 0.17. For blunt-snouted lenok the similar value of tau (0.52 + 0.21) was reached by comparison of three geographically farthest populations (divided by approx. 1000 km) with each other. Two forms of lenok showed essential genetic differences--tau = 1.86 + 0.56. Estimation of tau between lenoks and taimen amounts to 3.25 + 0.89. Phylogeny of lenok and taimen and relationships between two forms of lenok on the East of the area are discussed.
运用12种限制性内切酶对同域分布区（阿穆尔河流域）的钝吻细鳞鲑和尖吻细鳞鲑、两个异域种群（东北和南滨海边疆区）的钝吻细鳞鲑以及哲罗鱼进行了线粒体DNA分析。解析出9个线粒体DNA克隆：每种细鳞鲑各4个，哲罗鱼1个。对一个尖吻细鳞鲑样本测得的线粒体DNA核苷酸差异平均百分比（τ）为0.51 + 0.17。通过比较三个地理距离最远（相距约1000公里）的钝吻细鳞鲑种群，得出其相似的τ值（0.52 + 0.21）。两种细鳞鲑表现出显著的遗传差异——τ = 1.86 + 0.56。细鳞鲑与哲罗鱼之间的τ值估计为3.25 + 0.89。文中讨论了细鳞鲑和哲罗鱼的系统发育以及该区域东部两种细鳞鲑之间的关系。
