New germplasm conservation orchard (GCO) in Clinton county

This orchard was established three years ago to preserve the genetic material of the Indiana American chestnuts at the Duke orchard at Purdue. The Duke trees were all cloned from old existing chestnuts from all over Indiana. Unfortunately, the Duke chestnuts have all become severely blighted, and we are in danger of loosing this valuable genetic material which we would like to use to breed blight resistant trees in the future. We were partially successful in treating the Duke trees with fungicide but we feel that the safest strategy is to reproduce the entire Duke orchard in a separate location far enough away that the seedlings could avoid blight for several years. This is why the new chestnut orchard was planted on farm land in Clinton county, Indiana.

Unfortunately, we have found blight on a few of the new trees. On October 6, 2022 chapter president Glenn Kotnik revisited this orchard and found the blight is now well controlled after a single fungicide application. Most of the trees look healthy, are growing well, and are showing their fall colors.

Small Stem Assays involve inoculating young chestnut stems with the blight fungus and monitoring the resulting cankers, allowing researchers to assess how well different trees respond to infection.

You don't find out if the tree is resistant until it matures. That could be a decade later.

Last week, staff at TACF’s national office in Asheville joined Carolinas Chapter President Peggy McDonald, husband Bob, and Chapter board member Jon Taylor for a hike at Albert Mountain in Western NC to visit wild American chestnut trees in search of flowering catkins.

During their venture, the team also came across a few cool amphibians: a red-legged salamander, which only inhabits portions of the southern Appalachian Mountains, and a red-spotted newt, which is much more common, but its brilliant red is stunning!

Of course, the biggest thrill was seeing large surviving chestnut trees and, as the day wrapped up, collecting some beautiful catkins that were high in the canopy of a tree on the way down the mountain. Pollen collected from the catkins will be used in TACF’s southern region breeding program.

Whoa. Fascinating that some mature American Chestnuts have survived the blight. Taking pollen from these survivors is such a great idea. I didn't realize there were any survivors in NC.

Ils sont en fleur au Québec aussi, ça fait du bien de les voir grandir.

Fantastic

Trying to figure out if you found an American chestnut or a Chinese chestnut? These identifiers should help!

I love it when the music is up front and the narration is in the background. Awesome.

Every business in every city should have to plant a tree every year as part of their yearly licensing.

“Though I do not believe that a plant will spring up where no seed has been, I have great faith in a seed. Convince me that you have a seed there, and I am prepared to expect wonders.” Henry David Thoreau

Im hoping to see this in my lifetime
