Korean white pine is one of the important silvicultural species due its quality timber in addition to edible pine-nut production. Selective breeding method is under progress to improve growth and nut production for this species. This study was carried out to obtain genetic information necessary for establishing advanced generation seed orchard, such as genetic parameters and efficiency of early selection. Open-pollinated cones were collected from 50 plus trees. In the spring of 1986, test plantations were established at 3 different sites with 4-year-old seedlings. Seedling height was measured from age 5 to 10 in plantations. Genetic and phenotypic correlations based on the log of the ratio of two ages (LAR) were expressed as simple regression with statistical significance (r2= 0.7862 and 0.8256, respectively). If 20 years is presumed to mature, the most efficient age for early selection is 3 years after planting with efficiency of 1.96.
Key words: Korean white pine, early selection efficiency, genetic correlation, heritability, log age ratio
