Abstract

In this study, the genetic diversity of the commercial Hanwoo population was monitored through the analysis of genotype information of a total of 33,300 heads. Set1 is a group that has the dam's genotype. Set2 is a group without dam’s genotype. As a result, it was confirmed that the genetic diversity of the analysis group was well maintained. The locus with the highest diversity identified is TGLA53. On the other hand, the locus with the lowest diversity was identified for TGLA126. Of the mismatched individuals with the dam’s genotype, 58% identified only one KPN. Monitoring using genetic information is necessary for the development of the Hanwoo industry and the enhancement of the efficiency of improvement projects.
