16年生无性系测定林方差分析结果表明,早期子代测定林中家系的优、中、劣单株并不能完全决定其无性系的后期表现;优良家系中选择出的优良单株(无性系)经过无性系评价,筛选出的优良无性系居多,但家系间树高差异显著、胸径差异不显著;无性系间树高差异显著、胸径差异不显著;8805组入选的12个无性系树高均值大于组内均值的12.5％,8806组入选的7个无性系树高均值大于组内均值的13.5％。
The result of ANOVA of 16-year-old clones showed that the superior, moderate and inferior single-line individuals of early-generation offspring could not completely determine the later performance of clones. The fine lines (clones) After clonal evaluation, most of the excellent clones were screened out, but there was significant difference in tree height between the two families. There was no significant difference in DBH between clones. There was significant difference in tree height between clones and no significant difference in DBH. Among 8805 groups, Which is larger than 12.5% of the mean value in the group. The mean value of tree height of the 7 clones selected by the 8,806 groups is greater than 13.5% of the mean value in the group.
