The statistics of height growth and diameter growth of semi-sibs of Picea koraiensis on three-year-old (60 pedigree) and 11-year-old (46 pedigree) colonies were carried out. The results showed that there were 48 families with 3-year-old fine lines, of which 15 families were excellent families in both regions.
