摘　　要：采用12个杉木家系,分别在福建省将乐国有林场(JL)、福建省官庄国有林场(GZ)、福建省洋口国有林场(YK)进行多点试验,并利用混合线性模型对5年生的试验林生长性状进行遗传参数估计,筛选杉木耐瘠薄家系。结果表明:杉木早期没有表现出显著的基因与环境互作;以家系一般配合力作为杉木家系选择的标准,筛选出洋口林场的11号、10号、2号、4号家系,将乐林场的3号、8号家系,官庄林场的3号、7号、9号、5号家系作为杉木耐瘠薄新品种选择的候选材料。Twelve Chinese fir families were used for multi-envrioments trials in Jiangle state-owned forest,Guanzhuang State-owned Forest and Yangkou State-owned Forest in Fujian Province,and genetic parameters were estimated for their 5-year growth traits using a mixed linear model to screen Chinese fir families for barrenness tolerance.The results showed that Chinese fir did not show significant gene-environment interactions in the early stage;the general cooperativeness of the families were used as a criterion for fir family selection,among which,family 11,10,2,and 4 in Yangkou State-owned Forest,family 3 and 8 in Jiangle State-owned Forest and family 3,7,9,and 5 in Guanzhuang State-owned Forest,could be used as materials for selection of new barren-tolerant varieties of Chinese fir.
