This study was carried out to investigate the genetic variation and the expected breeding values for future progeny of Hanwoo(Korean Native Cattle) under the sire and the animal individual models. For the animal models, the breeding values of the sires and dams without records and the progeny with records were estimated simultaneously through the relationship among animals. To estimate breeding values, a total of 2,690 individuals from 8 provinces was evaluated. The results obtained from this study were as follows; The ranges of rank correlation coefficients between the predicted differences from the sire model and the breeding values from animal individual model within the same traits were 0.83∼1.00 for body weight, 0.59∼1.00 for chest girth and 0.62∼1.00 for shank circumference through every months of age. From this result, it was about the same to rank sires either by the predicted difference under sire model or by the breeding value under animal individual model. The ranges of breeding values of body weight, chest girth and shank circumference at 12 to 18 months of age were -25.55∼23.94kg, -9.00∼6.21cm, -1.04∼0.69cm for sire, -30.23∼23.94kg, -11.48∼6.13cm, -0.71∼0.84cm for dam, -57.78∼37.14kg, -18.63∼11.59cm, -1.10∼1.04cm for progeny respectively. The range of breeding values for dam and progeny showed room for individual selection to produce superior bulls and heifers. Rank correlation coefficients of breeding values for total individuals(sire, dam, progeny) evaluated through every months of age were 0.64∼0.79 between body weight and chest girth, 0.32∼0.64 between body weight and shank circumference, and 0.29∼0.65 between chest girth and shank circumference. From this result, we can expect genetic gains simultaneously for the chest girth and shank circumference indirectly if we select the individuals by the breeding values for the body weights. When select for the sires and dams of 10 heads each by the rank of the breeding values for the body weight, It appeared that the genetic improvements of body weight for the next generation from the means of estimated breeding values would be 13.3∼15.5kg at 12∼18 months of age. From selection on body weight, the chest girth and shank circumference were also expected to be increased indirectly about 1.6∼2.8cm and 0.1∼0.2cm at 12 to 18 months of age.
