Chestnut Chat is the official webinar of The American Chestnut Foundation. Episode 52, September 20, 2024. Assisting Evolution: The History of American Chestnut Breeding and New Innovations Special guests Mike Aucott, John Scrivani, and Jared Westbrook will discuss American chestnut breeding from the 1950s to the present, exploring various methods, goals, and the results that have been achieved. Mike will discuss the F1-F2-F3 Timber Type program and Large Surviving Americans (LSAs) established at Codorus State Park, PA. The late Dave Armstrong originally planted these to diversify the breeding materials available to TACF. John will discuss the Connecticut Agricultural Experiment Station’s (CAES) Timber B1s and B2s, LSAs, and advance backcross tree planted at Lesesne State Forest in central Virginia. Jared will discuss plans for TACF’s recurrent genomic selection program (RGS) and how we are using trees described by Mike and John to supplement populations of backcross trees located among TACF’s network of growers.
