摘　　要：通过在华北落叶松无性系造林试验中对苗高和地径进行的调查分析,结果表明:华北落叶松无性系间在苗高、地径生长上均存在极显著差异,苗高遗传力为0.71,地径遗传力0.88;通过苗高单性状选择,初步选出15个优良无性系。After clonal afforestation trial of Larix principis-rupprechtii,the investigation of seedling height&ground diameter shows that there is a significant difference in seedling height&ground diameter growth between the clones of Larix principis-rupprechtii.Fifteen excellent clones were selected;the seedling height heritability is 1.71,and the ground diameter heritability is 0.88;fifteen superior were preliminarily selected by through single-trait selection.
