Earlier this year, several hundred of the chestnut trees in our chestnut orchard were inoculated with two different strains of chestnut blight. Last week a group from the American Chestnut Foundation came and evaluated the inoculations. We were pleased that many of the trees showed good resistance to the blight. The trees with the weakest resistance will be cut down and the trees with the strongest resistance will be kept for further breeding purposes.
This tree is an example of good resistance to the blight inoculation. The cracks in the bark are an indication that the tree is fighting the blight and is “walling off” the blight to keep it from spreading.
This tree has blight around the crotch of the tree from a naturally occurring source. It looks like the blight is really bad, but the tree actually has good resistance in the way it is fighting the blight. The chestnut orchard is an interesting project, and our family is learning a lot from caring for it. We are looking forward to what happens in the future.
