Phenotype Data
Phenotypic data were collected in November 2022 from each of the 1177 genotypes in the IUFRO population at John F. Kennedy Arboretum in Wexford, Ireland (52.315N, -6.941W). Diameter at breast (DBH) height was taken at 1.3m from the base of the tree using a steel DBH tape. Height was recorded for each tree using a vertex transponder (Hagloff V) to represent the distance from ground level to tree tip.
