Growth characters such as height, DBH, crown width, branch length and branch diameter were measured from 23 clones of plus trees of Pinus koraiensis. The results were as follows; 1) Differences between the largest and smallest clones were amounted to 41% in height, 81% in DBH, 50% in crown width, 55% in branch length and 83% in branch diameter. 2) There were significant differences between clones in every growth characters and correlation coefficients between growth characters were positive and significant (r = 0.418^*-0.917^(**)). 3) The broad sense heritabilities were 0.46 for height, 0.45 for DBH, 0.28 for crown width, 0.26 for branch length and 0.18 for branch diameter. 4) The genetic gains predicted for each characters were ranged from 4.1% to 11.1%, when selecting the best 3 out of 23 clones.
