To evaluate and select elite Larix kaempferi materials, three growth traits and six wood properties of 60 L. kaempferi clones from four provenances were analyzed. The ANOVA results indicated significant differences (p < 0.01) in all the investigated characteristics (height, diameter at breast height, volume, hemicellulose content, cellulose content and lignin content) among clones within provenances. The phenotypic and genotypic coefficients of variation among clones ranged from 6.65% to 25.66% and from 3.42% to 22.27%, respectively. The clone repeatability of all traits ranged from 0.51 to 0.97. The phenotypic and genetic correlation coefficients between different traits ranged from −0.66 to 0.98 and − 0.90 to 0.98, respectively. Principal component analysis showed that the first two components explained 54.29% of the total variance, and growth traits and some wood properties showed higher absolute values. Under a selection rate of 10%, using the method of comprehensively evaluating multiple traits to select clones, six elite clones were selected based on their growth traits, wood properties, and both growth traits and wood properties together. For these groups of clones, the genetic gains ranged from 5.27 to 21.53%, 8.02 to 29.95%, and 4.27 to 18.07%, respectively. These selected clones could provide a base material for the selection of improved varieties.

评估和选择精英日本落叶松材料，三个生长性状和60个6种木材性质日本落叶松从种源无性系进行了分析。方差分析结果表明存在显着差异（p 来源之间的所有克隆中所有调查的特征（高度，胸径，直径，体积，半纤维素含量，纤维素含量和木质素含量）均<0.01。克隆之间的表型和基因型变异系数分别为6.65％至25.66％和3.42％至22.27％。所有性状的克隆重复性介于0.51至0.97之间。不同性状之间的表型和遗传相关系数分别为-0.66至0.98和-0.90至0.98。主成分分析表明，前两个成分占总方差的54.29％，生长性状和某些木材特性显示出较高的绝对值。在选择率为10％的情况下，使用综合评估多个性状的方法来选择克隆，根据它们的生长特性，木材特性以及生长特性和木材特性一起选择了六个精英克隆。对于这些克隆组，遗传增益分别为5.27％至21.53％，8.02％至29.95％和4.27％至18.07％。这些选择的克隆可为选择改良品种提供基础材料。
