【摘要】 为了保护大巴山地区的中蜂资源,试验采集重庆市城口县111只中蜂样本,采用线粒体DNA tRNAleu-COⅡ基因测序的方法对大巴山中蜂进行遗传多样性分析。结果表明:大巴山地区111只中蜂样本中共检测到单倍型21种,群体的单倍型多样度(Hd)为0.859 0,平均核苷酸差异数(K)为2.482,核苷酸多样度(Pi)为0.006 01,其中有5个单倍型属于首次发现的单倍型。说明大巴山地区中蜂的遗传多样性较高,具有独特的遗传背景,其开发潜力,尤其是保种和育种价值很大。更多还原

【Abstract】 To investigate the Apis cerana cerana Fabricius resources in Daba Mountain,111 Apis cerana samples were collected from the Cheng-kou County of Chongqing,and then the genetic diversity was analyzed based on mitochondrial tRNAleu-COⅡ sequences. The results showed that there were 21 haplotypes among the 111 samples,and the haplotype diversity( Hd) was 0. 859 0; the average number of nucleotide differences( K) was 2. 482,the nucleotide diversity( Pi) was 0. 006 01. It was also found that,5 of the 21 haplotypes were the first to be found.The results indicated that Apis cerana cerana in the Daba Mountain had relatively higher genetic diversity and exhbited its own unique genetic background. Therefore,the Daba mountain has a potential for the developmentand the conservation of species and breeding.更多还原
