| 摘 要： | 采用沙黄松天然林自由授粉家系７年生树干材积的材料，分析了联合选择遗传增益结构模式。结果表明：亚群体间存在极显著差异，亚群体内家系间差异不显著；联合选择增益结构模式为亚群体间７２．４４％、亚群体内家系间３．５５％、单株间２４．０１％。

| Abstract: | T he structural patterns of genetic gain
through the combined selection have been analysed by adopting the volume materials of
7-year- old stems from the open pollination families of Pinus massoniana var.shaxianensis
natural forest.The results demonstrate that there are ex- tremely sig nificant differences among
subpopulations while the differences among the families within subpopulations are not
significant.The structural patterns of genetic gain through the com- bined selection are 72.44%,
3.55%and 24.01%among subpopulations, families within subpopu-lations and single
trees,respectively. |
