Genetic Control of Wood Quality Traits in Forest Systems
Summary
The quality of wood in forest trees is governed by the interplay of genetic factors, developmental processes and environmental influences. Genetic variation underpins key traits such as wood density, fibre dimensions, microfibril angle and resin composition, each of which affects mechanical strength, stiffness, pulp yield and industrial value. Advances in quantitative genetics and molecular biology have enabled the identification of genomic regions associated with these traits, paving the way for marker-assisted and genomic selection. High heritabilities and favourable genetic correlations between desirable wood properties facilitate multi-trait breeding, although adverse correlations—such as those between rapid growth and wood stiffness—present challenges. Integrating genetic control with silvicultural practices, such as thinning regimes and site selection, allows for optimisation of both productivity and quality. Modern phenotyping technologies, including acoustic velocity assessment and high-resolution imaging, permit early-life screening of wood properties. As climate change intensifies, genetically informed strategies will be essential to secure sustainable timber supplies, enhance carbon sequestration and maintain ecosystem resilience across global forest landscapes.

Genetic Control of Wood Quality Traits in Forest Systems publication trend
The graph below shows the total number of articles in genetic control of wood quality traits in forest systems across all publications each year (not limited to Nature Index journals).
Technical terms
Heritability: Proportion of phenotypic variation in a trait attributable to additive genetic factors.
Breeding value: Estimated genetic merit of an individual for a given trait based on progeny performance.
Quantitative trait locus (QTL): Genomic region associated with the variation of a quantitative trait.
Genetic correlation: Measure of shared genetic control between two traits, indicating how selection on one trait affects the other.
Cambial age: Number of annual growth rings from the pith, reflecting the developmental stage of the wood.
Microfibril angle (MFA): Orientation angle of cellulose microfibrils in the cell wall, influencing wood stiffness and strength.
