摘要
对红松自然分布区内３个亚区、９个地点、１０８株优树子代１０年生树高测定的结果表明，亚区间和家系／地点／亚区间差异显著、极显著，北亚区在带岭生长表现最好；亚区、地点／亚区、家系／地点／亚区间遗传力分别为０８３６、０５３７、０３６５。
In the natural distric area of Pinus koraiensis ,3 subregions,9 sites and 108 progeny of plus tree with 10 years high growing were detemined.The results showed that the variation between subregions and family/site/subregion was significance.The growth in northern subregion was the best in Dailing,the heritability in subregion/site/subregion,family/site/subregion were respective 0836,0537 and 0365.
