| 摘 要： | 通过对１４个省共１１２个优良家系的区域性试验，测定杉木优良家系遗传稳定性和生长潜力的研究，结果表明：对于杉木的材积生长，其家系间、地点间、家系×地点间交互效应均存在极为显著的差异，家系遗传力为０．７３５６。根据遗传稳定性参数和家系材积生长情况，选出８个优良速生家系，平均材积比杉木１．５代种子园遗传增益达１７％。各地点分别选出８个最速生家系，其材积增益为１１％─５１％，增产效果十分明显。

| Abstract: | The results indicated that the fanilly geneiic ability of Cunninghamia lanceolata volume growth in this regional experiment was 0.7356，the volume gains of eight fastest growing families respectively selected from variousplaces were 11─51 ％ and the yield increase effect was very evident. |
