| 摘 要： | [目的]为定向育种、良种选育和制定种质标准提供参考依据。[方法]以红白锦鲤肾细胞为材料,采用PHA和秋水仙素活体注射体细胞体内培养法,经空气干燥制备了染色体,并对其染色体核型进行分析。[结果]红白锦鲤的染色体数目分布在92～100条,相对长度最长的为（29.67±2.21）‰,最短的为（13.53±0.08）‰。[结论]红白锦鲤的染色体数2n=100,核型公式为：22m＋34sm＋22st＋22t,染色体臂数（NF）=156。

| Abstract: | [Objective]The study aimed to provide the reference for directional breeding,selective improved variety and making variety standard. [Method]With renal cell of red-white ornamental carp as test material,chromosome was made by PHA,colchicine injection and air drying method,meanwhile,the karyotype was analyzed. [Result]The numbers of chromosomes were 92-100,longest relative length was (29. 67 ± 2. 21)‰,the shortest one was (13. 53 ±0. 08)‰. numbers of chromosomes of [Conclusion]The chromosome number of the species was 2n = 100,the karyotype formula was 2n = 100,22m +34sm +22st +22t,the numbers of chromosome arm (NF) were 156. |
