초록

경주지방에서 사육 중인 경주개(동경이) 51두를 대상으로 8개의 microsatellite marker을 이용하여 DNA형을 분석한 결과 대립 유전자 수는 $4{\sim}12$개(평균 8.5개)로 검출되었으며 Expected heterozygosit와 PIC는 각각 $0.6162{\sim}0.8746$(평균 0.7587)와 $0.5461{\sim}0.8512$(평균 0.7167)으로 나타났고, PEZ3, PEZ6, PEZ12, FHC2054 marker는 PIC가 0.7이상으로 나타났다. 이들 marker는 향후 동경이의 개체식별 및 친자확인에 유용하게 쓰일 수 있다. 공시재료 51두 중 사육가에 의해 혈통이 알려진 5두를 대상으로 microsatellite marker를 이용하여 혈통을 분석한 결과 3두에서 현재 가계도와 일치하지 않았다. 따라서 앞으로 더 많은 연구를 통해서 동경이에 대한 체계적인 혈통 정립이 이루어져야 할 것이다.

In this study, we analyzed the microsatellite DNA poly-morphisms for pedigree verification in Kyungju dog (Dongkyung-i) which is one of the Korean breed dogs. A total of 51 Dongkyung-i samples were genotyped using 8 microsatellite markers. The number of alleles observed at single locus ranged from 4 to 12, with average number of alleles per locus of 8.5. The expected heterozygosity and polymorphic information contents (PIC) values of the 8 microsatellite loci were $0.6162{\sim}0.8746$ (mean 0.7587) and $0.5461{\sim}0.8512$ (mean 0.7167), respectively. Of the 8 markers, PEZ3, PEZ6, PEZ12 and FHC2054 loci had relatively high PIC values (>0.7) in Dongkyung-i. Pedigree verification of Dongkyung-i was analyzed based on alleles observed. The results of the parentage testing were noted significant differences compared with breeders. These results show basic information of conservation and research in Dongkyung-i, and further studies of genetic pedigree in Dongkyung-i will be needed.
