摘要:
为探讨国内外典型鹅品种资源的遗传多样性与系统进化关系,本文利用Sanger测序,测定了5个大、中、小型鹅品种,共100个样本的线粒体DNA细胞色素b(mtDNA Cytb)基因部分序列,并使用MEGA、DNASP等软件进行分析。结果显示:在矫正后的mtDNA Cytb基因606 bp序列中发现了23个多态性位点,占总碱基数的3.79%,其中简约信息位点21个,占多态性位点的91.30%;5个品种共具有31个单倍型,其中共享单倍型2个。5个鹅品种按种间遗传距离的远近,大致可分成2大类族群,霍尔多巴吉鹅为一类,其他4个鹅品种为一类。狮头鹅、浙东白鹅、扬州鹅、太湖鹅的核苷酸多样性和单倍型多样性高;其Fu's Fs值和Tajima's D值均为正值且符合中性检验,同时碱基错配分布曲线呈多峰分布,表明群体趋于稳定。霍尔多巴吉鹅群体内未发现多态位点,且与上述4个鹅品种遗传距离较远,可作为父本或母本与上述4个大、中、小型鹅品种杂交,利用杂交优势培育专用品系或生产商品代霍杂鹅。
