Abstract

The study includes 41 sample sets of chum salmon from the northern part of its geographic range analyzed at ten microsatellite loci. In the northern part of the range of Asian chum salmon, the following groups of samples are clearly distinguished: “Magadan oblast,” “Northern Kamchatka,” “Penzhina River,” and “Anadyr River basin.” Populations of chum salmon from the Apuka River and the “Koryak Upland” group show low genetic differentiation from other groups. There is a positive relationship between the latitude and the average expected heterozygosity in this part of the range. Chum salmon of the Penzhina River shows close genetic relationship to chum salmon from the Anadyr River basin, probably because of gene flow.

基于微卫星标记的亚洲北春鲑（Oncorhynchus keta W.）的分化

摘要

该研究包括在十个微卫星基因座处分析的来自其地理范围北部的41种鲑鱼样品。在亚洲鲑鱼产区的北部，可以清楚地区分以下几组样品：“马达加丹州”，“堪察加北部”，“彭增纳河”和“阿纳迪尔河流域”。来自阿普卡河和“科里亚克山地”群体的鲑鱼种群显示出与其他群体的低遗传分化。在该范围的这一部分中，纬度与平均预期杂合度之间存在正相关关系。Penzhina河的鲑鱼与Anadyr河流域的鲑鱼有着密切的遗传关系，这可能是由于基因流动所致。
