[Method] Eight primers were selected and used in the DNA fingerprinting technique amplified fragment length polymorphism (AFLP) to detect the purity of 30 Shanxi lean meat pigs. [Result] A total of 206 AFLP markers were obtained; 3-15 bands were obtained from each primer. The similarity index of population in Shanxi local pigs was 0.931 on average. [Conclusion] AFLP is suitable for detection of genomic DNA, and the genetic purity of SD-Ⅲ line is higher.展开更多
