The hybrid loach of ssp. (female) and (male) has the desirable trait of growth performance. There is no report of the complete genome of this hybrid. In this study, the complete mitochondrial genome of this hybrid loach was obtained, and the genome is 16,569 bp in length, including two ribosomal RNA genes. Thirteen proteins-coding genes, 22 transfer RNA genes, and a non-coding control region, the gene composition and order of which was similar to most reported from other vertebrates. Sequence analysis showed that the overall base composition is 29.5% for A, 27.5% for T, 26.4% for C, and 16.6% for G. The sequence is a slight A + T bias of 57.0%. The phylogenetic tree showed that the hybrid loach to be one of , and the relationships of were closer. Also the mitochondrial genome sequence of loach were aligned by BLAST, compared with Cobitinae the sequence similarity could reach >90%, and the similarity to was >99%. Mitogenome information from this study could be a useful basis for conservation and phylogenetics of this hybrid loach.
某亚种（雌性）和（雄性）的杂交泥鳅具有生长性能优良的特性。关于这种杂交泥鳅的完整基因组尚无报道。在本研究中，获得了这种杂交泥鳅的完整线粒体基因组，该基因组长度为16,569 bp，包括两个核糖体RNA基因。13个蛋白质编码基因、22个转运RNA基因和一个非编码控制区，其基因组成和顺序与其他脊椎动物报道的大多数情况相似。序列分析表明，总体碱基组成为A占29.5%、T占27.5%、C占26.4%、G占16.6%。该序列存在轻微的A+T偏向，为57.0%。系统发育树表明，杂交泥鳅属于某一类，且该类的关系更为密切。此外，通过BLAST对泥鳅的线粒体基因组序列进行比对，与花鳅亚科相比，序列相似性可达>90%，与某物种的相似性>99%。本研究的线粒体基因组信息可为这种杂交泥鳅的保护和系统发育研究提供有用的依据。
