对抚仙金线巴鱼和滇池金线巴鱼的线粒体细胞色素ｂ基因的部分序列进行了测定及分析。发现①两亚种间共有３８个变异位点，占总位点的１０．９％；②转换明显多于颠换，且第三位置上的同义突变最为常见；③两亚种间的遗传距离为０．１１４，高于已研究过的淡水鱼类种内遗传距离的最大值，接近种间的较高值，是否仍然把它们视为同种的两个亚种看来值得进一步研究。
The partial sequences of the mitochondrial cytochrome b gene in the goldfish of the genus Fuxian and Jindian of Dianchi Lake were determined and analyzed. The results showed that there were 38 variation sites between two sub-species, accounting for 10.9% of the total sites; ② The transformation was more than the transversion, and the synonymous mutation in the third position was the most common; ③ The genetic between two subspecies The distance of 0.114, which is above the maximum genetic distances studied in freshwater fish species, approaching the higher values of the species, remains to be considered as two subspecies of the same species which warrants further study.
