Maryland Chapter

Sugarloaf Mountain Orchard

The Maryland Chapter operates an orchard at the base of Sugarloaf Mountain in cooperation with Stronghold, Inc., which owns the mountain. Two orchards were started in 1970 with irradiated nuts. The orchards are described as the East Field and the West Field.   The West Field orchard is no longer in use.

East Field – Originally planted in 1970 with an estimated 1000 irradiated seeds. Most have succumbed to chestnut blight and phytophthora. However, some  27 remaining trees have been used as mother trees in our breeding program.  Also, a backcross orchard of BC3 seeds (Manahan 41 x AG247) and an experimental orchard to study hypovirulence were planted in 2007 . However, most of these trees have been killed by the blight, phytophthora or deer.

Fall work is in full swing at Meadowview! 🌰 Lucinda and Dan are planting a Castanea seguinii from Dr. Hill Craddock (University of Tennessee at Chattanooga) in our Castanetum, home to chestnut relatives from around the world. Nearby, we’re selecting top performers from a 2018 progeny test—thinning the stand to release the best 10% for future breeding success. #AmericanChestnut #RestorationInProgress #ChestnutResearch #ForestRestoration #MeadowviewResearchFarms #Castanetum #ScienceInTheField ...

Join us on Friday, November 21, 2025, from 11:30AM – 1:00PM (ET), for the next LIVE Chestnut Chat webinar.

Our special guest, Dr. Jessica Rutkoski, is a small grains breeder with a talent for explaining the fundamentals of breeding and quantitative genetics. In her talk, she will describe how modern tools such as genomic selection and high-throughput phenotyping can speed up improvement for multiple traits—and how these technologies can be effectively applied to TACF’s American chestnut breeding program. Jessica is a quantitative geneticist and leads the winter wheat breeding program at the University of Illinois at Urbana-Champaign.

🍂 As autumn arrives, chestnut trees at TACF’s Meadowview Research Farms enter dormancy, leaves turning gold and brown before falling. This cozy pause is nature’s renewal, while staff use the time to plan, prepare, and continually refine methods across the field, nursery, and lab. Dormancy sets the stage for a strong spring and a year of progress in chestnut science. 🌳
