| 摘要: |
| 利用4个微卫星标记对西北地区的固原鸡、固原红鸡和略阳乌鸡群体进行遗传变异分析。结果表明,地方品种固原鸡、略阳鸡和培育品种固原红鸡在4个位点的平均杂合度分别为0.748 7,0.709 2和0.733 2,平均有效等位基因数分别为5.129 0,3.505 8和4.468 9,平均多态信息含量分别为0.716 6,0.646 6和0.570 4。表明固原鸡、略阳鸡和固原红鸡均具有较大的遗传变异。 |

| Study on genetic diversity in three northwest chicken populations |

| Abstract: |
| The evalution of genetic resource of three northwest chicken populations was analyzed by using microsatellite marker on 4 loci. The result indicated that the average heterozygos of natural Guyuan chicken, natural Lueyang chicken and cultivate Guyuan red chicken was 0. 748 7,0. 709 2 and 0. 733 2,respectively,the mean effective number allelic was 5. 129 0,3. 505 8 and 4. 468 9, respectively, the average polymorphism information content was 0. 716 6,0. 646 6 and 0. 570 4, respectively. The study indicated that there were abundant genetic diversity in three chicken populations, which provided theoratical basis for protection and exploitation of the northwest chicken breeds. |
