| 摘 要： | 开展鱼类核型分析对鱼类的遗传、变异、分类、系统演化、性别决定、杂交育种以及环境污染监测等研究具有重要意义。鲇形目鱼类在我国水产养殖中占有重要地位，同时也是研究鱼类染色体进化与性染色体分化的良好材料。本文综述了我国35种鲇形目鱼类及其杂交子一代和多倍体的核型研究进展，分析了不同类群中的核型特征，并对部分类群的染色体进化关系进行了探讨，最后展望了鲇形目鱼类核型研究的发展趋势。本文将为我国鲇形目鱼类的染色体与基因组进化等研究提供参考。

| Abstract: | Karyotype analyses of fish are of great significance for studies on genetics, variation, classification, systematic evolution, sex determination, cross breeding and environmental pollution monitoring. As an important aquaculture fish family in China, Siluriformes are the good models to study evolution of fish chromosomes and differentiation of sex chromosomes. In the present study, progresses of karyotype studies on 35 catfishes in China, including their hybrids and polyploids, were reviewed when characteristics of the karyotypes and evolutionary relationships of chromosomes among different taxas were analyzed. Finally, development trends of catfish karyotype studies were forecasted. This study will provide useful references for future studies on chromosomal and genomic evolution in Siluriformes. |
