Abstract
Eucalyptus globulus (Labill.) is the most widely planted eucalypt for pulpwood in temperate regions of the world. Breeding to improve pulp properties of this species has been hampered by the long time between planting and pulp trait assessment and the high cost of estimating pulp traits. Identifying and employing allelic variants that associate with superior pulp yield and quality has the potential to assist breeding programs. Before this strategy can deliver benefits, detailed knowledge of population structure, nucleotide diversity, haplotype diversity and linkage disequilibrium (LD) must be collected. To address this, 20 wood quality candidate genes were sequenced in 8 to 28 Eucalyptus glo..
