Georgia Chapter

Research and Breeding

Here is information and some links to the types of research and breeding activities that GA-TACF supports.

TACF Research and Breeding

Mother Trees

Chapter members spend hours searching the mountains and hillsides of Georgia for American chestnut root sprouts that can be placed into our breeding program. One of the Chapter’s first pure American chestnut trees was found on Springer Mountain by Thomas Fowler and placed in the breeding program during the Chapter’s first breeding season. Since then many other trees have been located with the “Klaus” tree near Warm Springs bringing attention world wide as the most southern tree in the piedmont area.

Without the help of volunteers identifying new trees, our breeding program would come to a halt. Each “mother tree” can only be used to cross with one type of resistant pollen from TACF’s Meadowview Research Farm to produce about 100 backcross trees. This is usually accomplished within 2 years. The more trees we find, the more diverse the gene pool will become.

Orchards

Once nuts are harvested from the resulting backcrosses a suitable orchard must be located to plant them. Berry College was the first to offer a site that would house over 200 trees. The University of Georgia’s Mountain Research and Education Center in Blairsville became our second backcross orchard. Since then we have received many offers for orchard sites that are now in the testing stage. We test for soil suitability, predator protection and overall tree care to determine the best locations for advanced backcross trees. If you are interested in hosting a backcross or demonstration orchard, please contact us at gro.fca@retpahcag.

On Friday March 6 faculty and staff at the University of North Georgia (UNG) added about 70 chestnuts by direct seeding to the Hurricane Creek orchard near Dahlonega. Karrie Ann Fadroski, Outreach and Engagement Coordinator for UNG’s Environmental Leadership Center (ELC) and Stacie James, Program Coordinator for the ELC, were assisted by Dr. Martin Cipollini, President and Science Coordinator for GA-TACF as well as several UNG student volunteers. Student participants included Chestnut student intern Lillian McGinnis, Hurricane Creek student intern Jason Richardson, Conservation student intern Reece Maxwell, Kylee Melton, Ava Minor, Mary Alice Olewicz, and Jack Nicholas.

This orchard is designed to screen hybrid chestnuts for Phytophthora Root Rot (PRR) resistance (pure American chestnuts are entirely susceptible to PRR). Seeds selected for this orchard come from trees known or suspected to carry PRR resistance, in this case from two trees at the Berry College backcross orchard. Read elsewhere on our Facebook page about how to protect chestnuts from this lethal disease if you have planted susceptible trees.

To learn more about this work and what you can do to become involved, please come to our annual meeting on May 2 at the Gwinnett Environmental & Heritage Center in Buford. Details are forthcoming, but the meeting will be held in the morning with lunch and a tour at Cloudland Vineyards in the early afternoon.

Hard to believe these students are in their late 30s now...

Coincidentally, exactly 17 years ago on March 6, 2009, Berry College students planted the parents of the seeds planted at UNG. Here are just a couple pictures from that day.

Dr. Martin Cipollini, President and Science Coordinator of The Georgia Chapter of The American Chestnut Foundation, presented an overview of the organization's Recurrent Genomic Selection (RGS) chestnut breeding program during the Tennessee chapter's annual meeting at Tennessee Tech, subsequently chairing the Southern Regional Science meeting held in conjunction with the TN-TACF meeting. At the latter meeting, chapter leaders discussed how to cooperate to implement RGS regionally and initiated plans for the coming breeding season. They also welcomed newly hired TACF Regional Science Coordinator Zach Anderson who has been working with Dr. Hill Craddock at the University of Tennessee - Chattanooga. Zach's office will be located in Chattanooga. The American Chestnut Foundation ... See MoreSee Less
