[Metbod] Cell division was synchronized by the pepripheral blood lymphocyte culture and the excessive dosage of thymine deoxyribonucleoside, and R-band of Cervus nippon hortulorum chromosomes was also analyzed by RBG-banding technique. Result The number of haploid chromosome banding increased to 400. The R-band of No. 1, No. 2, No. 3, No. 4, chromosome X and Y were almost just opposite to the high-resolution G band of them. The terminal of chromosomes except No. 21, No. 24 and No. 28 were all pos- itive deeply stained. E Conclusion] R-band of Cervus nippon hortulorum chromosomes can be manifested by RBG-binding technique.展开更多

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
