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。
Systematic studies on the data of growth and wood properties of 13-year-old and 16-year-old Chinese fir plantations under full-distribution test of two provenances of Chinese fir showed that the tree height, diameter at breast height, volume, wood proportion, With rich genetic variation, the genetic variation rate of its provenance is above average. From 57 provenances, 8 elite provenances were selected from Jinping, Fujian, Jian’ou, Guangxi Rongshui, Chong’an, Pucheng, Daejeon, Wuping and Nanping, among which, Jinping in Guizhou and Jian’ou in Fujian The provenances of good growth materials, Guangxi Rongshui, Jinping of Guizhou, Datian of Fujian and Nanping were good provenances. The genetic gain of village plot was 41.7% ~ 82.3%, and the growth traits and wood proportion were not significant However, the genetic correlation between the two was negative, and reached a highly negative correlation with the increase of forest age.
