【摘要】 为了揭示河南省不同黄河鲤养殖群体之间的遗传差异,本研究通过线粒体COI基因对5个黄河鲤群体的遗传多样性进行了研究。5个群体中单倍型数最多的为荥阳水产良种场群体,最少的为洛阳水产技术推广站群体,其它群体的单倍型数均为3;各个群体的基因多样性从0.200到0.750不等,最高的为河南省水产良种繁育场的群体;各群体的核苷酸多样性范围为0.00063到0.00228,最高的为荥阳水产良种场群体,最低的为洛阳市水产技术推广站群体。分子方差分析表明黄河鲤将近90%的变异来自于群体内,说明整体上群体间分化较小。该项研究为黄河鲤增殖放流、新品种培育和资源保护等研究提供一定依据。更多还原

【Abstract】 The mitochondrial COI gene of five Yellow River carp populations was sequenced to reveal their genetic diversity. In the five populations, the maximum number of haplotype was the population of Xingyang Aquatic Breeding Farm. The least was the population of Luoyang Aquatic Technology Promotion Station. The other haplotype number was 3. Genetic diversity of the populations ranged from 0.200 to 0.750. The highest was the population of Henan Aquatic Breeding Farm. The population of Luoyang Aquatic Technology Promotion Station was lower than other populations. Nucleotide diversity of the populations was in the range of 0.00063 to 0.00228. The highest was the population of Xingyang Aquatic Breeding Farm and the lowest was the population of Luoyang Aquaculture Technology Promotion Station. Analysis of molecular variance shew that nearly 90% of the variation came from the interior of the populations and genetic differentiation was small between different populations. The study provided some basis for artificial releasing, breeding new varieties, and resources protection of the Yellow River carp.更多还原
