A sample of 3 breed crossed marketing hogs (Duroc × Landrace × Large White, n=133) was evaluated and measured for marbling score of loin eye muscle and the average backfat thickness. The average marbling score was 2.30 and the average backfat thickness was 3.20cm. The effect of sire was close to statistically significant to the marbling score (P$lt;.06) and it was significant to the backfat thickness (P$lt;.01). The effects of dam within sire, sex and age were not significant to both of marbling score and backfat thickness, The heritabilities for marbling score and backfat thickness were 0.37±0.19 and 1.12±0.58, respectively. The genetic correlation between marbling score and backfat thickness was 0.18.
