| 摘 要： | 目的]探讨4个鲤鱼群体的形态学差异。方法]综合传统形态学（可数性状、可量性状）数据和框架测定数据,通过多元变量统计分析,对黄河鲤鱼、野生四鼻须鲤鱼、养殖四鼻须鲤鱼和吴淞江苏州段鲤鱼的形态差异和种系关系进行了研究。结果]4个群体在可数性状方面无显著差异（P〉0.05）;判别分析表明,4个群体的单一群体判别率分别为87.5%、78.1%、73.5%和96.8%,用优选的几项比例变量进行判别,综合判别准确率为83.7%;聚类分析表明,黄河鲤鱼群体和野生四鼻须鲤鱼群体聚为一支,养殖四鼻须鲤鱼群体和吴淞江苏州段鲤鱼群体聚为另一支;主成分分析表明,4个群体间形态差异主要系头部、尾部及鱼体垂直轴方面差异所致。结论]为四鼻须鲤鱼这一珍贵鲤鱼品系的提纯复壮提供了理论依据。

| Abstract: | Objective] The aim was to discuss the morphological differences of four carp populations.Method] Based on traditional morphological data（including countable and measurable characters） and framework data,the morphological differences and phylogenesis of Yellow River carp population（YR）,wild four-naris carp population（WF）,farmed four-naris carp population（FF） and carp population from Suzhou section of Wusong River（WR） were studied by means of multivariate analysis.Result] There was no significant difference（P〉0.05） in countable characters among four carp populations.Discriminant analysis showed the discriminating accuracy of YR,WF,FF and WR population were 87.5%,78.1%,73.5% and 96.8% respectively,and the synthetic discriminating accuracy of four populations was up to 83.7%.In addition,cluster analysis revealed that YR population and WF population clustered together,while FF population and WR population clustered together.Principal component analysis indicated that the morphological differences among four populations mainly came from the head,tail and vertical axis of fish.Conclusion] The study could provide theoretical foundations for the purification and rejuvenation of rare four-naris carp. |
