摘　　要：对2002年营建的陈山红心杉1代种子园41个半同胞家系子代14年生林分进行调查研究,结果表明:红心杉1代种子园子代家系14年生林分平均树高、胸径、单株材积分别为11.31 m、15.44 cm、0.0578 m3。树高和单株材积在家系间存在显著差异。根据参试家系14年生的材积指标初步筛选出优良家系30个,入选家系平均树高、胸径、单株材积分别为11.45 m、15.75 cm、0.0605 m3,与对照相比树高、胸径、单株材积遗传增益分别为3.94%、2.79%和13.13%,现实增益分别为10.94%、13.75%和36.89%。In this paper, 41 half-sib families of the first generation Cunninghamia lanceolata seed orchard established in2002 were researched. The studied forests were 14 years old. The results showed that, the average tree height, DBH, and individual volume of the 41 half-sib families were 11.31 m, 15.44 cm and 0.0578 m^3. There was significant differences among families in the tree height and volume. According to volume index of volunteers＇ family on 14 years old, thirty superior families were preliminary selected. The average tree height, DBH and individual volume of the selected families were 11.45 m, 15.75 cm and 0.0605 m^3. Compared with the control, the selected families＇ genetic gain of tree height, DBH and volume were 3.94%, 2.79% and 13.13% respectively. And the selected families＇ reality gain of tree height, DBH and volume were10.94%, 13.75% and 36.89%, respectively.
