“…Wu et al (2011) reported that significant differences in D, TH, and SWV were found among 19 Eucalyptus hybrid clones planted in southern China. In 12-year-old Tectona grandis trees planted in Indonesia, significant differences in growth characteristics (D, TH, and stem volume) and the SWV were observed among 15 clones (Hidayati et al 2013). Our results for D, TH, and SWV are consistent with those obtained by previous studies on Z. serrata and other hardwood species (Endo et al 1998;Wu et al 2011;Hidayati et al 2013).…”

“…In a previous study, significant differences in D and TH were observed in 4-year-old Z. serrata trees planted at the same site of the present study (Endo et al 1998). Among-family variation or clonal variation in growth characteristics and wood quality have been reported in other hardwood species (Wu et al 2011;Hidayati et al 2013). Wu et al (2011) reported that significant differences in D, TH, and SWV were found among 19 Eucalyptus hybrid clones planted in southern China.…”

“…Theoretically, the ratio between genotypic and phenotypic variances can be simply expressed as heritability or repeatability (Falconer and Mackay 1996); therefore, moderate repeatability values (variance components of the half-sib family) for D, TH, and SWV were observed in the present study. Low to moderate repeatability values (0.12-0.56) have been obtained for D and TH in E. globulus, Acacia auriculiformis, and T. grandis (Volker et al 1990;Hai et al 2008;Hidayati et al 2013). However, moderate to high repeatability values for SWV in hardwood species have been reported.…”

“…However, moderate to high repeatability values for SWV in hardwood species have been reported. For example, Hidayati et al (2013) reported that the repeatability of the SWV in 12-year-old T. grandis trees from 15 clones was 0.27. In addition, Wu et al (2011) reported that the repeatability value of SWV in Eucalyptus hybrid clones was 0.77.…”

Zelkova serrata is an important hardwood species for the timber industry in Japan. Tree breeding programs for this species have mainly focused on growth characteristics such as stem diameter (D), tree height (TH), stem form, and branching. In order to fulfill timber industry needs, wood quality improvement should be included in the tree breeding program of this species. In the present study, growth characteristics, such as D and TH, and the stress-wave velocity (SWV), which is highly correlated with Young's modulus of wood, were measured for 20-year-old Z. serrata from eight half-sib families planted in a progeny test site with three different initial spacings. Significant differences in all the measured characteristics were found among the eight half-sib families. The variance components of the half-sib families for D, TH, and SWV were 27.2%, 47.3%, and 33.5%, respectively. These results indicate that all the measured characteristics of this species could be improved by tree breeding programs. In addition, only low correlation coefficients were obtained between the growth characteristics and SWV, indicating that extensive selection on SWV in tree breeding programs may not always lead to a reduction in yield volume.
