Abstract

The objective of present study was to ascertain parentage of Thoroughbred(TB) horses in Korea. A total of 2,029 TB horse samples including 993 foal samples for parentage testing were genotyped for nine international minimum standard markers(AHT4, 5, ASB2, HMS3, 6, 7, HTG4, 10, and VHL20). This method consisted of multiplexing PCR procedure, and showed reasonable amplification of all PCR products. Genotyping was performed with an ABI 310 genetic analyzer. The number of alleles per locus varied from 5 to 11 with a mean value of 7.33 in TB. Expected heterozygosity was ranged from 0.544 to 0.837(mean 0.709) and the total exclusion probability of 9 microsatellites loci was 0.9978. Of the 9 markers, ASB2, HMS7 and HTG10 loci have relatively high PIC value(>0.7). All of the 993 foals were qualified by compatibility according to Mendelian fashion in the present DNA typing for parentage testing. These results suggest that the present DNA typing has high potential for parentage verification of TB horses.
