Is there a good app which lets you input your zip code, maybe also sun exposure and soil conditions, how many feet of width and height you have available, and then where it will spit out a list of well-suited tree specimens with some nice pictures of each?
Saw this really amazing video[0] the other day about American Chestnut Foundation's breeding program in Virginia to revive the American chestnut Basically they hybridized it with Chinese/Japanese chestnuts (which are blight resistant). Then they take the offspring, test for blight resistance and rebreed those back with purebred American chestnuts. Then they repeat the process. Take those offspring, select for blight…
Fwiw this is wrong -- it used to be 4 billion.

Why don't they use agrobacterium transfection, gene guns, or molecular techniques to directly transfer the resistance genes over? Do we not know what the genes themselves are? I'm not criticizing their technique! Nor do I think I know better. This is amazing and valuable work, and I'd love to know more.

It could also just be technology. This breeding program has been around for 50 years or so and CRISPR only really took off around 2011. In addition, the original CRISPR-Ca9 caused a lot of unintended changes in DNA and it's really critical that the new trees are morphologically equivalent to the original trees in order for the birds, insects, and animals that depended on them to resume their interactions. Newer technologies like CRISPR-Nickase are much more precise but also very recently developed

It's a tricky business, because chestnut had very particular properties, as wood, that made it quite valuable, and any gene interference, well ... who knows how it will change the resultant wood?
If this tree had a secret to cultivating a resistant strain that would be very awesome.
