淮南猪品种遗传特异性的AFLP分析
AFLP Analysis of the Genetic Specificity of Huainan Pig
摘要
Abstract
25 pairs of primers were used to analyse the Huainan pig which was the local variety in Henan province and the three foreign pigs of Duroc,Landrace, Yorkshire pigs with the AFLP method. With 25 pairs of primers, we detected 317 fragments in all, 79 fragments were polymorphic,accounting for 24.92 ％. Statistical analysis showed that the genetic index between Landrace and Yorkshire pigs was 0. 0070,which indicated that these two pigs had the closest genetic relationship, Huainan pig and Duroc, Yorkshire pig had the similar genetic distance index, which were 0. 0073,0.0075, respectively. With the choser genetic relationship, the genetic distance index between Huainan pig and Landrace was 0. 0078,genetic relationship between them was the farthest. The results showed that the Huainan pig had strong specificity,comparing with other introduced species,and with high breeding value,but also proved that AFLP technique could detect genetic variation and pig identification within the populations of pigs.关键词
