杉木早期生长性状多点遗传测定及耐瘠薄家系选择

The Multi-enviroment Trail of Chinese Fir Growth Traits and the Early Stage Selections for Superior Families with Leanness-resistant to Poor Soil

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。

Abstract: 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.
