I'm in the great white north, so the blight pressure may be less here, but I
have no trouble finding pure dentatas over 200 years old within 4 hours of my
house.
I belong to the Canadian Chestnut Council, and there are tested dentatas with as
much resistance as some of the hybrids..not as good as the pure Chinese, but
likely to live and set nuts for a long time. Another issue is hardiness. There
is one hybrid on the home place and it dies back in bad years...the pure
dentatas don't. I may cut the hybrid as soon as the pure ones come into
bearing. Right now there are so few nuts that I just eat them. When I start
getting enough to replant them in my woods, I'll cut the hybrid.

right on...that is what i have been doing for 25 years...it just takes a lot of
care and patience and hard work. you have to accept that American Chestnut takes
its own time...and be willing to keep fighting c.parasitica...some of the
original trees planted back in 1984 are 50 ft tall (12 in dbh) and still
producing viable nuts. most have died to the blight. have 4th generation
seedlings I am crossing through open pollination with strains from other areas
that i have collected through the years. this should build more resistancy in
time...they are all pure-American...no hybrids, no back-crossing.
