You can find updates on the regulatory status of Darling 58 on our Regulatory Status page. In addition, a (very) few mature American chestnuts still exist, apparently resistant to the blight. Much of this work is being done in collaboration Meantime, we are working to scale-up our capacity to produce and distribute trees are not blight resistant, such as seedling American chestnuts, or European x Japanese hybrids (including Colossal). That genetically modified organisms go through before they can be released. Our chestnuts come from a grafted orchard of many different blight resistant/tolerant strains and cultivars grown in USDA hardiness zone 6a, just a few miles. These trees to their historic native range, to benefit people and local ecosystemsĭarling 58 chestnuts are currently going through the federal regulatory review process This variety, Darling 58, shows enhanced tolerance to chestnutīlight thanks to a common gene that was inserted into its genome. Our project has produced an American chestnut variety with enhanced blight tolerance Tree, the American elm, Ulmus americana) and Septoria leaf spot and canker disease of hybrid poplar, Populus sp. (which is becoming a key biomass tree species). should note that these American Chestnut seedlings are not blight resistant. Such as Dutch-elm disease and elm yellows (which devastated another American heritage Nursery Note: Tree planters in the eastern part of the U.S. Will have broad applications in managing diseases affecting other important tree species The concepts, techniques, and gene cassettes we develop for the American chestnut Of putative resistant transgenic trees, collecting rare chestnut germplasm, and establishing Tissue culture and gene transfer into American chestnut trees, determining geneticĭiversity in surviving remnant chestnut populations, greenhouse and field testing Gene designs, identifying genes associated with Asian chestnut tolerance, chestnut Ongoing activities include basic research on various single and pyramided tolerant-enhancing Participation through the identification of rare remnant surviving chestnut trees,Ĭollecting and exchanging viable nuts, and establishing large restoration plantations The American Chestnut Project has evolved from basic research into a multifacetedĮndeavor, including identifying plant pathogen tolerance-enhancing genes, developingĪmerican chestnut tissue culture, field testing chestnut trees, encouraging public
Our goal is to reintroduce a population of these tolerant trees back into forestĮcosystems of the eastern United States. University of New York College of Environmental Science and Forestry (ESF) is to conductīasic and applied research that will lead to the development of a blight-tolerantĪmerican chestnut tree ( Castanea dentata).
