Growth and wood mechanical properties are important traits for solid wood improvement in industrial tree breeding programs. In this study, efforts were made to identify microsatellite markers associated with growth and wood mechanical traits in an industrial tree species Eucalyptus cloeziana F. Muell. (family Myrtaceae). Based on a total of 839 microsatellite markers, 84 were screened out for association mapping in 9.5-year-old height (H_9.5), diameter over bark at breast height (D_9.5), basic density (BD_9.5), green density (GD_9.5), modulus of elasticity (MOE_9.5), modulus of rupture (MOR_9.5), and compressive strength parallel to the grain (σ_(c,0)9.5). By applying the mixed linear model and the false discovery rate correction, a collective total of 13 loci were validated for significant association with traits (Q ≤ 0.05), including two loci in H_9.5, three in D_9.5, seven in BD_9.5, and three in MOE_9.5. However, no marker-trait association was found for the rest three traits GD_9.5, MOR_9.5, and σ_(c,0)9.5. The ratio of phenotypic variance explained (R²) by a significant locus ranged from 5.3 % to 43.1 %, with an average of 20.6 %. Favorable and/or unfavorable alleles were determined from the significant markers for each trait. Ten of the 13 significant loci were functionally homologous to known genes or predicted proteins. The novel set of significant loci identified here, along with their favorable alleles, can be used for tracking causative loci or genes and for marker-assisted breeding of the related traits.

生长和木材机械性能是工业树育种计划中实木改良的重要特征。在这项研究中，人们努力确定与工业树种桉树（Eucalyptus cloeziana F. Muell）的生长和木材机械性状有关的微卫星标记。（家庭桃金娘科）。基于总共839个微卫星标记，筛选出84个用于9.5岁身高（H _9.5），胸高处树皮直径（D _9.5），基本密度（BD _9.5），绿色密度（GD）的关联作图_9.5），弹性模量（MOE _9.5），断裂模量（MOR _9.5）和平行于晶粒（σ _{（c，0）9.5}）的抗压强度。通过将混合的线性模型和错误发现率校正，13个位点的集体总被验证为显著伴随性状（Q ≤0.05），包括两个位点在ħ _9.5，三个d _9.5，七在BD _9.5，和在MOE _9.5中排名第三。然而，未发现其余三个性状GD _9.5，MOR _9.5和σ _{（c，0）9.5的}标记性状关联。表型方差的比率说明了（R ²）的显着位点范围为5.3％至43.1％，平均为20.6％。从每个性状的重要标志物确定有利和/或不利等位基因。13个重要基因座中的10个在功能上与已知基因或预测的蛋白质同源。此处确定的新的重要基因座集及其有利的等位基因，可用于追踪致病性基因座或基因，以及用于相关性状的标记辅助育种。
