My parents are also doing this on their property, it is exciting, and I hope this new breed is resistant to the fungus.
Of course the proof is a forest of full grown trees, but there's every reason to expect this method will get us there.
They designed a brand new type of testing for resistance to be able to make the progress they've made as quickly as they have. Instead of testing a whole tree they can effectively test blight resistance on a single leaf, allowing their time between generations to be measured in weeks rather than years. (Time to first leaf, rather than time to whole tree).
I am very excited. What was strange is that in order to accept the trees, you had to agree to an entire set of restrictions. You can not sell any nuts was one; another was you must cut down the tree if you ever sell your property, I suppose there is an exception if the new owner also signs onto to the agreement. Seemed a little awkward, but still worth it.
