All these characters were parsimoniously analyzed using paup4 . 0 . mitochondrial dna cytochrome b gene was adopted to discuss the sequences variations among the populations of sinibrama species and used to reconstruct the phylogenetic relationships between the genus sinibrama and some related cultrinae genera . on the basis of the analytical result , the hypothesized relationship of cultrinae by previous authors were testified 运用线粒体dna细胞色素b基因序列对华鳊属及其相关类群进行了系统发育重建，以探讨华鳊属鱼类不同地理居群的cytb序列变异及与其他相关类群的系统发育关系，并验证前人的一些研究结果。
