摘　　要：对福建柏17个地理种源和48个家系6～7年生幼林期的树高、胸径、材积生长进行调查分析，结果表明：福建柏在山区、半山区、丘陵区的生长差异均存在极显著差异，树高、胸径、材积遗传力分别达0．5561～0．9034、0．6303～0．9140、0．6701～0．9143，反映该差异主要受遗传因素影响；种源×地点交互作用显著，其3个主要性状生长量在山区的表现优于在半山区和丘陵区的表现；根据材积遗传增益选出适宜不同生态环境造林地的7个优良种源和16个家系（其材积遗传增益分别为18．99％～94．96％、16．78％～215．75％），种源优树99株和家系优树140株（其材积遗传增益比优良种源和家系平均值分别提高63．66％～257．61％、138．33％～878．34％）。The heredity variability of the height, diameter and volume growth, interaction effect of biomass and circumstance of 6～7 years old Fokienia hodginsii plantation including 17 geographical provenances and 48 families in Hunan province were studied. The results indicated that there were obvious differences in the height, diameter and volume growth at mountain, middle mountain and hill. Heritability of the height, diameter and volume is 0.5561～0.9034, 0.630 3～0.9140, 0.670 1～0.914 3 respectively. Between the provenances and environment of interaction, the rank of the height, diameter and volume growth was mountain〉middle mountain area〉hill. Based on the selection standard on the volume growth exceeded （15 %） of average provenances, 7 superior provenances and 16 families were tentatively selected with the genetic gain of 18.99%～94.96%,16.78%～215.75% respectively. Based on the selection standard on the volume growth exceeded of average provenances, 99 superior provenance plus trees and 140 families plus trees were tentatively selected with the genetic gain of 63.66%～257.61% ,138.33%～878. 34% respectively.
