Dennis Fulbright at Michigan State University and Jeanne Romero-Severson at the University of Notre Dame are developing genetic tests to detect the ancestry of chestnut selections and cultivars.
The success of this project depends on a broadly based sample of American, European, Japanese and Chinese chestnut trees. We have a very good set of Chinese chestnuts but need more of the other species. If you believe your tree is a "pure species" chestnut, whether American, European, or Japanese, send us a sample, with your ID and the tree's location. We also need more Ozark and Allegheny chinkapins.
