对红松3个种源60个家系3年生子代苗的研究结果表明,红松种源间及种内家系间苗高、地径和二次生长高均有显著差异;种源间的变异量大于种源内家系间的变异量;苗高的遗传变异大于地径;苗高、地径、当年高和二次生长高的家系遗传力分别是0.860,0.556,0.660,0.184。 The results of 3-year-old seedlings of 60 pedigrees from 3 provenances of Pinus koraiensis showed that there were significant differences in height, diameter and secondary growth among different provenances and their families. The variation between provenances Which is larger than the variation among families within the provenance. The genetic variation of the seedling height is larger than the ground diameter. The heritability of the height and diameter of the plant in the high and secondary growth year are 0.860, 0.556, 0.660 and 0.184, respectively.
