Chikso(brindle cow) is a subspecies of Hanwoo, and is one of the Korea’s native breeds. It has the characteristics of being strong and strong against disease. The black stripes around its body resemble that of a tiger. In this study, 9,663 Chikso in South Korea were classified into 4 groups based on their birth year. The polymorphism analysis of Chikso whole groups revealed the average number of alleles in each marker (number of alleles), the expected heterozygosity (HEX ), the observed heterozygosity (HOB ), the polymorphism information content (PIC), and the FIS mean as 16.2, 0.769, 0.759, 0.737 and 0.0061, respectively. For group D, with the birth year 2018-2020, the HEX and HOB were 0.767 and 0.760 respectively and the PIC was 0.734. The average observed heterozygosity (HOB ) for each generation of the Chikso group was confirmed to be 0.753, and it was confirmed that it gradually increased from group A (0.749) to group C (0.751), and increased sharply in group D (0.760). The average of the PIC was found to be 0.732, and the most recently born group, group D (2018-2020), had the highest value of 0.734. It was confirmed that the FIS value also gradually decreased with the recent generation. The result of this study are expected to be used for enhancing the efficiency of Hanwoo Industry.
