为评价和利用杉木种质资源，对8年生杉木第3代种质资源自由授粉子代测定林进行调查分析，在生长性状评价的基础上对优良种质进行选择。结果表明：杉木林分生长良好，8年生时平均树高、胸径、单株立木材积分别为9．31 m、11．88 cm、0．06291 m3，年均生长量分别达到1．16 m、1．49 cm、0．00786 m3。各年度树高、胸径、单株立木材积的遗传变异系数分别为2．157％～6．061％、1．826％～2．769％、4．895％～6．907％，家系遗传力分别为0?348～0?690、0?167～0?328、0?217～0?367。从参试的97个家系中选择出25个速生优良家系，其8年生时平均树高、胸径、单株立木材积分别为9．70 m、12．60 cm、0．07221 m3，分别较群体均值大4．19％、6．06％、14．78％，遗传增益分别为1．88％、1．98％和5．42％。这一结果可为杉木第3代种子园建园材料选择提供依据。

To evaluate and utilize superior Chinese fir germplasm, growth traits( tree height, DBH and stem volume) at age 8 from open pollinated progeny test of the 3rd germplasm of Chinese fir were investigated and analyzed, and superior germplasm of Chinese fir was selected. The overall mean of tree height, DBH and stem volume was 9.31 m,11.88 cm and 0.062 91 m3 , with annual 1?16 m,1.49 cm,and 0.007 86 m3 growth, respectively. The genetic variation coefficient of tree height, DBH and stem volume was 2. 157%-6. 061%, 1. 826%-2. 769% and 4. 895%-6. 907%, respectively. Family heritabilities of these traits were 0?348-0.690, 0.167-0.328 and 0.217-0.367 separately. 25 families from the total 97 families were selected, with mean value of tree height, DBH and stem volume was 9.70 m, 12.60 cm, 0.072 21 m3, and more 4.19%, 6.06% and 14.78% than sampled population, respectively. The genetic gain of these traits was 1?88%,1.98% and 5.42%, separately. The results provide evidences of selecting materials for the 3rd generation of Chi?nese fir seed orchard.
