| 摘 要： | 对选自中国南方的１１２个杉木自由授粉家系在八个测试点进行了生长性状的遗传评定。ＡＭＭＩ（加性主效应与复合交互效应）模型分析揭示存在着显著的家系与地点交互效应。根据家系平均ＡＭＭＩ估算和交互第一主分量轴得分对地点所作的聚类分析，以及地点间的遗传相关分析，测试点被划分成四个地点群，有证据表证，就生长性状而言，杉木的育种区早分可能与地理区域尤其是纬度带相重叠。１１２个自由授粉家系依据其交互ＰＣＡ１及平均

| Abstract: | The response of 112 open-pollinated Chinese fir (Cunninghamia lanceolata (Lamb. ) Hook) families from southern China was evaluated for stem volume at 8 test locations. The AMMI (additive main effects and multiplicative interaction model) analysis revealed a considerable family X site interaction. The sites were grouped into four sets from the results of cluster analysis of mean family AMMI1 estimates and interaction PCA1, and among-site genetic correlations among sites. It is evident that delimitation of breeding zone for Chinese fir may be overlaid with the geographical zone if selecting on growth. One hundred and twelve open-pollinated families were clustered into four classes by their IPCA1 values and mean stem values. The consolidation of families would not appear to be corresponding with their origin. |
