摘要
通过福建柏19个地理种源和48个家系造林试验,初步选择出10个优良种源和14个家系,其材积遗传增益分别为16.09%～88.70%、15.19%～184.80%.参照福建柏优树国家标准,在优良种源和家系林分中,选择出优树179株,其材积遗传增益比优良种源和家系分别提高17.45%～122.51%、3.30%～191.69%.
Based on provenance trial of 19 geography provenances and 48 families, 10 superior provenances and 14 families were tentatively selected with the volume genetic gain of 16.09 % - 88.70 %, 15.19 % - 184.80 % respectively. Based on national standard of Fokienia hodgiusii, 179 plus trees were selected with the volume genetic gain of 17.45 % - 122.51% ,3.30% - 191.69% than superior provenances and families respectively.
