The feasibility of adding wood quality traits as selection criteria in the Galician Pinus pinaster Aiton breeding program: case study

“…Similarly, negative correlations between growth traits and wood quality traits have been reported in several other pine species, such as Pinus contorta (Hayatgheibi et al 2017(Hayatgheibi et al , 2019, Pinus radiata (Wu et al 2008) and Pinus sylvestris (Hong et al 2014(Hong et al , 2015. In contrast, Larix kaempferi presented a positive correlation between diameter and BD (Fukatsu et al 2015), and diameter in Cryptomeria japonica was positively correlated with both BD and MOE (Yasuda et al 2021). Studies of P. radiata indicate that the higher the MOE d , the higher the tree slenderness (TS) (Lasserre et al 2008;Kimberley et al 2015;Watt and Trincado 2019).…”

“…Given their importance to the timber industry (Bacher and Krzosek 2014), a lot of literature has been published on these traits. In general, both traits are strongly and positively correlated with each other in conifers (Baltunis et al 2007;Hong et al 2014;Yasuda et al 2021) but, usually, negatively correlated with yield traits such as growth and form. Determining how BD and MOE behave with respect to other traits is critical to improving multiple traits simultaneously in a breeding program.…”

“…Regarding the basic density, we also found a quite high value for the individual heritability at the early age of 12 years, which then declined at age 24. By contrast, other pine species have shown higher individual heritabilities at ages close to 24 years, for example P. radiata (Gapare et al 2010), as well as other coniferous species (Chen et al 2014;Yasuda et al 2021). This age-related decrease in heritability was also observed in P. radiata (Baltunis et al 2007;Gapare et al 2010), and P. contorta (Hayatgheibi et al 2017).…”

Genomic Prediction of Tree Height, Wood Stiffness, and Male Flower Quantity Traits across Two Generations in Selected Individuals of Cryptomeria japonica D. Don (Japanese Cedar)

“…However, the seedling population has now been drastically reduced, and parental information could not be recovered. Because the recent research in C. japonica breeding has shown that clonal value could potentially be used as a proxy for the breeding value [52], the present study utilized the parental clonal value for the prediction of the clonal value of the offspring. To obtain the mid-parent value, the parents and their clonal values for the traits of interest must be known.…”

Decay and Termite Resistance of Wood Modified by High-Temperature Vapour-Phase Acetylation (HTVPA), a Simultaneous Acetylation and Heat Treatment Modification Process

“…Utilising wood not only enhances carbon sequestration in forests but also aligns with the principles of a circular economy, contributing to the goal of net-zero carbon emissions. Japanese cedar ( Cryptomeria japonica (L.f.) D. Don) is a prominent plantation tree species in East Asia [ 1 , 2 ]. Its extract exhibits excellent biological activity and can be used as a natural insecticide, wood preservative, fungicide, as well as in health care and medical products [ 3 , 4 , 5 , 6 , 7 , 8 ].…”
