<p>This research was conducted on 459 Landrace boars which came from France and the Unite States and were raised in Thuy Phuong Pig Research and Development Center between 2015 and 2017 to examine the heritability and estimate the breeding value (EBV) for interested traits, including average daily gain (ADG), back-fat thickness (BF), loin thickness (LT), and lean meat percentage (LMP). The heritabilities of ADG, BF, LT, and LMP were 0.43, 0.36, 0.26, and 0.40, respectively, which shows a large variation from moderate to high. 1% of the boars that had the best EBV for each traits was selected for the seed herd. This group showed the weight gain from +24.538 to +20.583, the backfat thickness from -1.564 to - 1.155, the loin thickness from +3.075 to +2.467, and the lean rate from +2.695 to +1.994. The accuracy of the estimated breeding value for the studied traits achieved in the best group was from 0.398 to 0.439.</p>
