| 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. |
