The present study was carried out to investigate the redcell types of horse breeds. A total of 210 horses (73 Korean native horses, 118 crossbreed horses, and 19 Mongolian horses) were tested a redcell types by serological procedure, and their phenotypes and gene frequencies were estimated. The blood groups phenotypes observed with highest frequency were Aa (27.4%, 63.6%, 63.2%), Ca (97.3%, 94.9%, 89.5%), K- (97.3%, 99.2%, 84.2%), Pa (39.7%, 44.9%, 42.1%), and Ua (71.2%, 70.3%, 63.2%) in the Korean native horse, crossbreed horse, and Mongolian horse, respectively. In the D system and Q system, phenotypes observed with highest frequency were Dbcm/dghm (12.3%), Dbcm/cgm (14.4%), Dcgm/dghm (15.8%), and Qc (56.2%), Qabc (36.4%), Qc (31.6%) in the Korean native horse, crossbreed horse, and Mongolian horse, respectively. Alleles observed with highest frequency were A- (0.287), Ca(0.827), Ddghm (0.226), K- (0.985), Pa (0.358), Qc (0.494), U-(0.529) in the Korean native horse, Aa (0.529), Ca (0.776), Dbcm (0.306), K- (0.995), P- (0.531), Q- (0.504), U- (0.548) in crossbreed horse, and Aa (0.421), Ca (0.895), Ddghm (0.421), K- (0.842), Pa (0.447), Qc (0.448), Ua (0.632) in Mongolian horse. Dcfgk and D- alleles were not detected in these horses. These results present basic information for estimating the genetic relationships between the Korean native horse, and developing a system for parentage verification and individual identification in these horses.
