| 中文摘要: |
| 本研究的目的在于认识兰州鲇染色体组特征,为兰州鲇的细胞遗传学和人工育种研究提供基础参考资料。以兰州鲇培养肾细胞为材料,采用空气干燥法,考察了兰州鲇的染色体组型。结果表明：兰州鲇的染色体数2n=58,核型公式为2n=20m 18sm 16st 4t,染色体总臂数(NF)为96。通过比较分析认为,兰州鲇在鲇属鱼类中属于较为原始的类群。 |

| This study aimed to understand the chromosome characteristics of Silurus lanzhouensis, therefore providing basic data for cytogenetic and artificial breeding studies of this species. The chromosomes of cultured kidney cells of Silurus lanzhouensis prepared by air-drying technique were elucidated. The results showed that: Silurus lanzhouensis has 2n=58 chromosomes; the karyotype formula is 2n=20m 18sm 16st 4t; the total number of arms (NF) is 96. Compared with the karyotype of other fishes, it was concluded that Silurus lanzhouensis is a more ancestral group among fishes of Silurus. |
