Resin canal size (top), area (middle) and density (bottom) for four 6-year-old P. radiata families at increasing distance from the pith (A-E 2 cm radial increments). Families 133 and 144 were chosen for high and families 105 and 165 for low resin canal density 2 cm from the pith. Triangles depict mean values; percentages are the coefficient of variation of the trait at each radial position

Resin defects can substantially decrease timber value in Pinus radiata, a commercial forest plantation species known for its good machinability. Tree breeding is a common approach to improve economic viability and product quality in commercial forestry. This study evaluated resin canal features in a P. radiata breeding population at two sites. Phen...
