Based on 13 years'studies,this paper selected some clone of Chinese fir with fast growth and superior timber properties through excellent provenances,population and individual trees.According to investigation data,there were singnifficant differences among those clones in DBH,height,individual volume,wood basal density and fibre length and with high broad heritability.The average of the DBH,height,individual volume,wood basal density and fibre length of those selected clones of Chinese fir were 16.8 cm,11.0 m,0.133 1 m3,0.319 3 g·cm-3 and 331 7 μm respectively in 12 years old.The genetic gains on DBH,height,individual volume,wood basal density and fibre length were 27.99%,8.09%,94.29%,6.72% and 4.53% respectively comparing with the contrast.
