| 摘 要： | 利用鸡基因组中5个微卫星标记,检测了边鸡群体的遗传多样性,并以大骨鸡做了比较分析。同时探讨了边鸡在国内5个地方鸡种中的系统地位。结果表明,5个微卫星位点共检测到38个等位基因,其中ADL0146位点的等位基因数最少(5个),而ADL0136和ADL0185两个位点的等位基因数最多(9个),平均等位基因数为7.6个.边鸡群体内比大骨鸡群体有更丰富的遗传多样性。聚类分析结果显示,边鸡与大骨鸡亲缘关系最近。而与鲁西斗鸡亲缘关系最远。 |

| Abstract: | Genetic diversity of Bian chicken was assayed and contrasted with Dagu chicken on the basis of 5 mi-crosatellite DNA markers from the chicken Gene Bank,as well as,the phylogenitic status of Bian chicken was discussed among 5 native chicken breeds.The results showed,altogether,38 alleles were detected in 5 microsatellite loci,and among them,the least alleles (5)were detected by ADL0146,and the most alleles (9)were detected by ADL0136 and ADL0185. The average alleles number was 7.6 from 5 microsatellite loci .Genetic diversity in Bian chicken was more abundant than that of Dagu chicken.The cluster analysis indicated that the consanguinity was the nearest between Bian chicken and Dagu chicken breeds,and the furthest between Bian chicken Luxi fighting chicken. |
