    Description

    The goal of our research and development efforts is to generate new and/or improved selections of the American elm (Ulmus americana L.) with tolerance/resistance to Dutch elm disease (DED). The approaches we are taking for this effort include: 1) controlled breeding using known DED -tolerant selections, 2) controlled breeding using DED-tolerant selections and local escape/survivor trees from specific geographic areas to generate site-adapted and DED-tolerant selections, 3) screening of escape/survivor trees for tolerance to DED, and 4) identification of additional American elm escape/survivor trees across its range. Our efforts in these areas are described. Progeny trees generated from crosses of Delaware 2 x New Harmony, Valley Forge x New Harmony, R18-2 x New Harmony, and Valley Forge x R18-2 exhibited a significantly lower mean of foliar symptoms at 8 to 9 weeks compared to the susceptible control.
