초록
This study was conducted to elucidate the genetic relationships among native Korean cattlebreeds by analyzing genetic variations and distances. Relationships among Hanwoo, Koreanbrindle, Korean black, Jeju black, and Holstein cattle were evaluated using 15 microsatellitemarkers. Korean brindle and Korean black cattle had the closest relationship based on thelowest genetic distance being observed between these breeds. A Neighbor-Net tree created usingthe Reynolds distances indicated that Korean brindle and black cattle formed a group separatefrom the Hanwoo population. However, an Fst pairwise test revealed that Hanwoo, Koreanbrindle, and Korean black cattle differed significantly (P <0.01). Moreover, the results of thisstudy confirmed that Jeju black cattle became a separate established breed in Korea through apath different from that of cattle from inland regions, even though it is considered to be aKorean native breed. Overall, the results of our study indicate that Korean brindle and blackcattle are indeed native Korean breeds that maintain an endangered status.
