摘 要: | 本研究对全国不同区域121个杉木优良家系9年生材积生长量进行统计分析表明:家系平均遗传力高,家系间生长差异极显著,家系遗传变异系数大,家系方差分量占总分量13.2%;有76个家系材积生长量超过我场初级种子园后代,63个家系材积生长量超过洋口初级种子园后代,20个家系材积生长量超过我省优良家系6421号,其材积增益比我场种子园后代大25.4%─65.6%。

Abstract: | The analyses show that the average genetic abil ity of the families is high,the growth difference is ex-tremely significant among the families and the volume gains of twenty families are 25.4─65. 60% higher than thoseof the progenies in the seed orchard on Wuyi National Forest Farm. |
