Tom Saielli, TACF Southern Regional Coordinator, and Larry Taylor, TN-TACF member, inspect a trial planting of American chestnut trees in a light gap at the Eagle Point Railroad in preparation for a large B3F3 progeny test on this beautiful Cumberland Plateau location.
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.
