对融安县西山林场1984年营造的25年生的85个杉木( Cunninghamia lanceolata)半同胞家系子代林的树高、胸径和材积指标进行了分析，结果表明：各家系在胸径、树高和材积等生长性状的差异均达到了极显著或显著水平。胸径、树高和材积增益大于对照10%的家系数量分别占参试家系的42．3%、27．1%和47．1%。以生长量差异为依据，筛选出了西山园广运5、所园红泥坡3、山口园山口4、林朵6等26个综合增益显著的家系，其最高胸径、树高和材积增益分别达46．7%、72．6%和134．9%。

The tree height, DBH, and volume were analyzed for 25-year-old plantations of eighty-five Chinese fir half-sib families planted in 1984 in Xishan forest farm of Rong’ an county. The results showed that there were very significant or significant differences among all families in DBH, tree height and vol-ume. Among all the tested families, those with gains of DBH, tree height and volume 10% more than control, respectively accounted for 42. 3%, 27. 1% and 47. 1%. Based on the differences of growth, twenty-six families with comprehensively high gains were selected, such as Xishanyuanguangyun-5, Suoyuanhongnipo-3, Shankouyuanshankou-4 and Linduo -6. The highest gains of DBH, tree height and volume respectively reached 46. 7%, 72. 6% and 134. 9%.
