摘　　要：福建柏17个地理种源和48个家系6～7a生幼林期树高、胸径、材积生长在山区、半山区、丘陵区均有极显著差异,该差异主要受遗传因素影响。根据材积遗传增益大于优良种源或家系60%以上标准,选择出7个优良种源和16个家系优树239株。There were obvious differences in the height, diameter and volume growth of Fokienia hodginsii, a young forest 6- 7 years old in 17 geographical provenances and 48 families at mountain, middle mountain and hill. Heritability of the height, diameter and volume is 0.5561-0.9034, 0.6303-0.9140, 0.6701-0.9143 respectively. Among 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, 10 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 （60%） 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.
