摘要
运用微卫星技术检测10个地方鸡种的杂合度、多态信息含量和遗传距离,探讨种群间的亲缘关系和遗传特征。结果表明:各位点的杂合度为0.2675～0.8316、多态信息含量为0.2478～0.8082;各种群的平均杂合度为0.5564～0.7134、平均多态信息含量为0.4999～0.6808。矮小型黄鸡与其它地方鸡种间的亲缘关系较远,仙居鸡、白耳鸡、泰和鸡、北京油鸡、大骨鸡、萧山鸡距离较近;茶花鸡与固始鸡存在一定的关系;尤溪麻鸡与其它鸡种的距离相对较远。
In this test,mircrosatellites techenology was used to investigate the heterozygosity and PIC and genetic distance of dwarf-yellow chicken and some native breeds and search for the blood relationship and genetic characters.The result indicates that each locus heterozygosity range from0.2675to0.8316and the PIC range from0.2478to0.8082.Among various strains the mean heterozygosity range from0.5564to0.7134and mean PIC range from0.4999to0.6808.The blood relationship between native chicken breeds and dwarf-yellow chicken breed is far and among Xianju chicken,Baier chicken,Taihe silky chicken,Beijin fatty chicken,Big bone chicken and Xiaoshan chicken is close.There is some certain relationship between Camellia chicken and Gushi chicken.The relationship between Youxi chicken and other native breeds is relatively far.
