福建柏子代测定及优良家系的初期选择研究

1998年利用福建柏30个家系在福建省永春碧卿国有林场云峰工区营建子代测定林,2005年对8年生的试验林进行调查。调查数据经过统计分析,从参试的家系中选出6个优良家系,其材积、胸径、树高平均值分别达到0.033 339m3、11.31 cm、6.62m,平均遗传增益分别超过30%、9%、11%,这些优良家系可以作为福建柏种子园建园材料和无性繁殖材料。

A Study on Progeny Test and Superior Family Selection of Fokienia hodginsii

Using 30 plus trees seedlings of Fokienia hodginsii,progeny tests were built on state-owned forest farm of Biqing,Yongchun,Fujian in 1998.Based on the investigation of 8-year-old progeny tests,6 superior families were tentatively selected.The average tree volume,height and diameter of 6 superior families were above 0.033 339 m3,11.31 cm,6.62 m respectively which had average genetic gains above 30%,9%,11%.These superior families could be used for seed orchard and vegetative propagation.
