Effect of genotype on selected properties of young plantation-grown Eucalyptus pellita F. Muell. and its hybrids for structural applications

Abstract

Short-rotation plantation hardwoods are increasingly used to meet timber demand but are often harvested before optimal structural properties are achieved. This limits their suitability for high-value timber applications. Improving the mechanical properties of young trees through selective breeding is a viable strategy, particularly when supported by molecular tools. However, limited information exists on how genetic and phenotypic variation influence structural traits across the stem profile. This study assessed variation in the mechanical properties of Eucalyptus pellita and its hybrids to support breeding for structural timber. Modulus of elasticity (MOE), modulus of rupture (MOR), and com..
