Volunteers from the Tennessee Chapter of The American Chestnut Foundation are contributing in a significant way to the restoration of Castanea dentata to the southern Appalachian forest. This video “Chestnuts Gettin’ It On” illustrates the reproductive process of how we backcross chestnut trees.

For all you chestnut nerds out there, here's a great read!
From the abstract: Over a century after two introduced pathogens decimated American chestnut populations, breeding programs continue to incorporate resistance from Chinese chestnut to recover self-sustaining populations. Due to complex genetics of chestnut blight resistance, it is challenging to obtain trees with sufficient resistance and competitive growth. We developed high quality reference genomes for Chinese and American chestnut and leveraged large disease phenotype and genotype datasets to develop accurate genomic selection.
