| 摘 要： | 以肾细胞作材料,采用秋水仙素- -低渗- -空气干燥法对达赉湖野生银鲫的核型进行了分析,肾细胞染色体的数目统计分析表明,达赉湖野生银鲫染色体组是由150条基本染色体和6条小的超数染色体组成.染色体组型按着丝粒位置156条基本染色体可分为四组.银鲫的中部着丝点染色体(m)19对；亚中部着丝点染色体(sm)14对；亚端部着丝点染色体(st)9对；端部着丝点染色体(t)36对,染色体数目为156,核型公式2n=156,2n =38m+ 28sm+ 18st +72t,NF=222.染色体臂数(NF)222.

| Abstract: | Using the cells of kidney as material and colchi-cine——low concent ration——air drying method to make Chromosome Specimen of wild Silver Carassius auratus gibelio in dalai lake.Statistical analysis of the chromosome number of kidney cells shows that the chromosome set of Carassius auratus variety pengze consists of 150 basic chromosomes and several small supernumerary chromosomes.The 156 basic chromosomes can be divided into four sections according to the position of the centromere.There are 38 metacentric chromosomes,28 submetacentric chromosomes,18 subtelocentric chromosomes and 72 telocentric chromosomes.The chromosomes number is 156,The karyo formula is 2n = 38m + 28 sm + 18 st + 72 t,NF=222. |
