Genetic variations and correlations between growth traits, wood basic density, wood red core rate, form and quality traits of families were studied based on 25-year-old seed orchard open-pollinated progeny test of Chinese fir established at Weimin National Forest Farm of Shaowu in 1979. The results showed that there were very significant differences among families in tree height, DBH and stem volume, some differences among families in wood basic density, wood red core rate, stem straightness, stem fatness, branch angle and stem bark rate. Based on the correlative analysis, the correlations between growth traits and wood red core rate were very plus close but the correlations between growth traits and stem bark rate were very minus close. The early selection for Chinese fir could be carried out at 4-year-old with a low selection intensity for tree height and the final selection could be carried out at 18-year-old with a high selection intensity for stem volume. According to the synthetical analysis, 7 superior families and 12 superior individuals with good performance in growth, wood property, form and qulity traits were selected from 63 open-pollinated families tested.
