| 摘 要： | 对杉木种源两次全分布试验的13年生、16年生试验林的生长、材性测定资料进行系统研究表明，杉木种源间的树高、胸径、材积、木材比重、形数等性状都存在着丰富的遗传变异，其种源的遗传变异率在中等以上。从57个参试种源中，评选出贵州锦屏、福建建瓯、广西融水和福建崇安、浦城、大田、武平、南平共8个优良种源，其中贵州锦屏、福建建瓯为生长材质兼优的种源，广西融水、贵州锦屏、福建大田和南平为稳定性好的种源，村积遗传增益为41．7％～82．3％，生长性状与木材比重无显著的表型相关，但两者遗传相关呈负向，随林龄增加达到高度负相关。

| Abstract: | Determinations of the growth and timber properties of 13 - year - old and the 16 - year - old test forest showed that highth, chest diameter, volume and specific gravity of timber had great genetic variation among provenances. 8 fine provenances were selected from 57 provenances, of which,Jinping and Jian'ou had the advantages of rapid - growth and fine timber properties. Rongshui, Jinping, Datian and Nanping provenances had fine stabillity. Their genetic gain of timber volume was 41. 7%-82. 3%. Their growth performance and specific gravity of timber had no significant phenotypic correlation, but their genetic correlation was negative. |
