The genomie DNA of 27 different Cereus nippon hortulorum were analyzed by amplified fragment length polymorphism （AFLP）. 11,443 bands associated with genetic polymorphism among total 15,169 bands were obtained with 9 kinds of primer pairs and restriction endonuclease EcoRI/Msel, percentage of polymorphie band was 78.43%, 1,271 polymorphic locus were shown per primer pair. The AFLP data showed that average genetic similarity was 0.7841 （0.6809-0.8648）. 27 samples were classified into Group I and Group II with cluster analysis, and Group II was divided into five subgroups. The result of AFLP and cluster analysis concluded that there was high genetic variation, which associated with orientated artificial breed selection and breeding in the population. Genetic similarity of Group II-4 was the highest, more than 0.82, while genetic distance in this group was the shortest, from 0.1354 to 0.1563, which was coordinated with breeding record. All these showed that there was great genetic polymorphism among the deer population. The results laid the foundation for main quantitative trait locus （QTLs） of Cervus nippon hortulorum.展开更多
