| 摘 要： | 对应用套式设计的３个亚区，９个产地的１０８株红松优树子代１０年生树高测定表明，亚区间和家系／产地／亚区间差异显著、极显著、家系间的变异量相当于群体间的变异量。多重比较结果。超过７８个家系，占参试总数７２．２％；达显著水准超过对照５３％以上的有３人家系，占参试总数２．７％。

| Abstract: | Reasons of genetic variations of Pinus koraiensis were analyzed through experiments in this paper.Height of tenyearold young trees from 108 trees in three subregions and nine provenances were measured. Analysis indicates that remarkable difference exists between various subregions,families,and provenances. Compared with control,78 families have higher growth and three of them have a remarkable increment of 53%.\= |
