This study has evaluated the genomic estimated breeding value (GEBV) of the commercial Hanwoo population using the genomic best linear unbiased prediction (GBLUP) method and genomic information. Furthermore, it analyzed the accuracy and realized accuracy of the GEBV. 1,740 heads of the Hanwoo population which were analyzed using a single nucleotide polymorphism (SNP) Chip has selected as the test population. For carcass weight (CWT), eye muscle area (EMA), back fat thickness (BFT), and marbling score (MS), the mean GEBVs estimated using the GBLUP method were 3.819, 0.740, -0.248, and 0.041, respectively and the accuracy of each trait was 0.743, 0.728, 0.737, and 0.765, respectively. The accuracy of the breeding value was affected by heritability. The accuracy was estimated to be low in EMA with low heritability and high in MS with high heritability. Realized accuracy values of 0.522, 0.404, 0.444, and 0.539 for CWT, EMA, BFT, and MS, respectively, showing the same pattern as the accuracy value. The results of this study suggest that the breeding value of each individual can be estimated with higher accuracy by estimating the GEBV using the genomic information of 18,499 reference populations. If this method is used and applied to individual selection in a commercial Hanwoo population, more precise and economical individual selection is possible. In addition, continuous verification of the GBLUP model and establishment of a reference population suitable for commercial Hanwoo populations in Korea will enable a more accurate evaluation of individuals.

본 연구는 8배체 딸기에서 다수성인 자식계통을 육성하여 중간모본으로 이용하기 위해 수행하였다. ‘Benihoppe’ 자식계통 중 초세, 당도, 수량성 등 원예적 형질이 우수한 ‘원교 3114호’를 선발하게 되었다. ‘원교 3114호’의 주요 특성을 보면 초형은 직립형이고, 초세가 중간정도이고 화아분화가 빠르며 수량이 많다. 과형은 원추형이고 과색은 연적색이며, 화방 당 화수는 16개 정도이며 평균과중은 17 g이다. 당도와 산도는 대조품종과 비슷하지만 경도는 대조품종에 비해 낮다. 전체수량은 대조품종에 비해 아주 높았으나, 저온기 착과성이 떨어지고 엽수가 적으며 흰가루병, 잿빛곰팡이병, 응애 등 내병성에 약한 경향이 있어 재배품종보다는 신품종 육성 시 수량증진 효과를 기대할 수 있는 중간모본용으로 적합할 것으로 예상된다.
