“…As expected for black spruce, there were weak G × E interactions for wood traits in both subzones. These results agree with those of many other studies on conifers (Johnson and Gartner 2006, Chen et al 2014, Ratcliffe et al 2014.…”

“…In addition, these stands were analysed for SWV and SWV and was found to be significantly positively correlated to height and DBH. A similar correlation was also found by El-Kassaby et al [45], Lenz et al [12], Li et al [46], Ratcliff et al [47] and Wielinga et al [48].…”

“…Estimates of the heritability of SWV are widely available. For example, Lenz et al [12] observed a heritability of 0.78 in white spruce and Ratcliff et al [47] observed (Rep = 0.42) in western larch (Larix occidentalis Nutt. ).…”

Abstract:To avoid unintentional loss of wood quality when selecting for higher productivity in tree breeding programs, non-destructive methods for fast and reliable assessment of wood quality on standing trees are required. In this study, we tested and applied Pilodyn penetration (PP) and measures of stress wave velocity (SWV) in trees within a European larch (Larix decidua Mill.) breeding program. Through testing PP in 4267 trees on 21 afforestation sites across a broad climatic spectrum, we analysed the effects of climate, tree age, and site conditions on PP. Moreover, detailed measures within two selected stands allowed us to estimate measurement variation within and among trees in relation to the measurement angle and individual tree characteristics. We found significant variation of PP and SWV among forests stands, single trees, and even within trees, if measured on opposite sides in mountainous terrain. Both measurements exhibited a high degree of genetic determination, i.e., repeatability was 0.32-0.61 for PP and 0.56 for SWV, respectively. The obtained estimates for wood stiffness were comparable to measures on harvested wood samples of European or hybrid larch. Our results demonstrate that the integration of wood quality parameters into larch breeding programs is highly recommended, and reliable tools are available. Results are discussed in relation to environmental and measurement variation and methods to optimize field measurements are suggested.

“…On the other hand, Zobel and van Buijtenen (1989) also have emphasized that wood quality improvement should be an integral part of tree breeding programs. However, because a negative decline of wood quality associated with the selection for growth characteristics has been concerned in tree breeding programs, selecting plus-trees based on wood quality is important (Ratcliffe et al 2014).…”

“…Furthermore, Young's modulus has been also known to have major effect on product design and important in engineering (Bucur 2006). In addition, a rapid estimation of wood quality is crucial for the success of wood quality improvement in tree breeding programs (Ratcliffe et al 2014). Therefore, SWV is important and appropriate for evaluating Young's modulus of wood in tree breeding programs.…”

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.

Genetics of wood quality attributes in Western Larch

Abstract: & Context Wood quality traits are important to balance the negative decline of wood quality associated with selection for growth attributes in gymnosperm breeding programs. Obtaining wood quality estimates quickly is crucial for successful incorporation in breeding programs.
