中文摘要:
      为研究淇河鲫种质状况,采用了聚类分析、判别分析、主成分分析3种多元统计分析方法,对黄河、海河2个水系的淇河鲫、沁河鲫、金堤河鲫和北运河鲫4个鲫群体的可数、可量和框架形态性状进行了比较研究。结果表明:(1)与其它3个鲫群体相比,淇河鲫形态特异性比较显著。其侧线上鳞、侧线下鳞和臀鳍条数均值,均显著高于其它3群体鲫,其侧线鳞数均值低于金堤河鲫,淇河鲫在体厚、背鳍长度、躯干部长度和尾部长度、高度方面占有明显优势,在臀鳍长度、头部大小及体高方面有明显的劣势;(2)淇河鲫与北运河鲫有着较近的亲缘关系,金堤河鲫与沁河鲫有着较近的亲缘关系。相对于沁河鲫,淇河鲫与金堤河鲫亲缘关系更近;淇河鲫仍然有着较为独特的种质特征,外来种质的影响尚不显著。
英文摘要:
      In order to inquire into the genetic state of the C.aurutus in Qihe River, three multivariate statistics analysis methods including cluster analysis, discriminant analysis and principal component analysis were applied to study comparatively on meristic morphological characters, measurable and truss frameworks morphological characters of the four colonies C.aurutus in Qihe River, Jindihe River, Beiyunhe River and Qinhe River which belonged to Yellow River system and the Haihe River system respectively. The results showed: (1) Compared with the other three C.aurutus colonies, C.aurutus in Qihe River had significantly morphological specificity. The means of the scales above the lateral line, scales below the lateral line and the anal fin numbers of the C.aurutus in Qihe River were all significantly higher than that of the other three colonies C.aurutus, and its means of the scales of lateral line were lower than that of the C.aurutus in Jindihe River. The C.aurutus in Qihe River had significant advantages on its body width, length of dorsal fin, length of trunk, length and height of cauda, meanwhile it had significant disadvantages on the length of anal fin, the size of the head and the body depth. (2) There was close relationship between C.aurutus in Qihe River and the C.aurutus in the Beiyunhe River, C.aurutus in Jindihe River had close relationship with C.aurutus in Qinhe River. Compared with the C.aurutus in Qinhe River, the C.aurutus in Qihe River had a closer relationship with the C.aurutus in Jindihe River. The C.aurutus in Qihe River still preserved special genetic character, which had not significant influence from the exotic genetic.
