Growth and Survival of Hybrid Poplar and Populus Deltoidws Clones in East Central Wisconsin

Seventeen year growth, survival, and disease incidence for 38 poplar clones from six organizations were evaluated. Heritability estimates for height, diameter, and bole cankers were calculated for clones with adequate replication. Broad sense heritability estimates were 0.46 for height, 0.26 for diameter, and 0.39 for bole canker incidence. Growth ranged from 27 to 58 feet in height and 3.4 to 8.1 inches dbh. Survival and percent bole cankers both ranged from 0 to 100%. A strong site influence on growth was noted.
