Asexual propagation of oaks has proven difficult for the majority of Quercus species using traditional methods of grafting or rooting cuttings, with the exception of Q. robur. In order to develop improved oaks, clonal propagation methods are required along with an increased diversity of Quercus germplasm.
Cornell’s Urban Horticulture Institute (UHI) has been working towards addressing limitations in propagation and germplasm diversity through its long-term white oak breeding program. This program was initially developed between 2004-2006, when over 345 unique genotypes of hybrid white oaks were generated using 40-parent species from North America, Europe, and Asia.
The goal of this project has been to develop elite oaks with enhanced characteristics such as stress tolerance (drought, high pH, cold hardiness, pest, and disease resistance) and ornamental quality. On an annual basis, stock plants are coppiced, forcing juvenile shoots from the stumps. These shoots can then be used for tissue culture establishment, to induce rooting using a stool bed method or allowed to grow to be evaluated.
