| 摘 要： | 对安徽省皖南花猪、皖南黑猪、定远猪、圩猪、安庆六白猪等五个地方猪种Ag-NOR s多态性进行了分析,结果显示Ag-NOR s均数分别为3.69、3.67、3.17、3.73、3.50,众数为4;2个引进品种大约克夏和长白Ag-NOR s均数分别为2.14、2.11,众数为2。Ag-NOR s均定位于10号和8号染色体次缢痕区。从研究结果可以推断皖南花猪和圩猪的品种纯度较高,聚类分析可将5个地方猪种分为2类:皖南花猪、皖南黑猪和圩猪为第1类,定远猪和安庆六白猪为第2类。此外5个地方猪种和2个引进品种Ag-NOR s多态性还为中国猪种起源于亚洲野猪,欧洲猪种起源于欧洲野猪提供了进一步的依据。 |

| Abstract: | The polymorphism of Ag-NORs in Wannanhua pig, Wannanhei pig, Dingyuan pig, Wei pig and Anqingliubai pig were analyzed. The results showed that the mean numbers of Ag-NORs were 3.69, 3.67, 3.17, 3.73 and 3.50 respectively, and NOR mode beings of the five local species were all 4. The mean numbers of Large Yorkshire and Landrace were 2. 14 and 2. 11 respectively, and their mode beings were all 2. The sites of NORs were located on the secondary constriction of chromosome No. 8 and No. 10. The results provided an evidence that Wannanhua pig and Wei pig have higher purity. The five species of AnHui local pig can be classified into two clusters. The first included Wannanhua pig, Wannanhei pig and Wei pig, and the other included Dinyuan pig and Anqingliubai pig. The polymorphisms of Ag-NORs could also provide further evidence that Chinese domestic pig originated from Asian wild boar, but European pig from European wild boar. |
