Richard,
You can actually grow 100
varieties of pears that far south? I get the impression that a lot of them
simply don't get enough chill hours to bloom that far south. As for
growing Bartlett at all, I am baffled that you and Ethan mention high quality
pears that I've never dreamed of trying to grow here. David Lockwood, UT's
horticulture expert, says he's never seen a Bartlett tree here more than 4 years
old. I really don't hold out too much hope for some of the varieties I've
ordered, I just wanted to see what they were like before they died, and I didn't
know any other way to go about it.
The UT pear program would check
for resistance in seedlings by grafting a branch of Bartlett onto each tree, and
then inoculate the Bartlett with FB. If it stopped spreading when it met
the hybrid, the seedling was considered resistant. Morgan is apparently
one of the few Bartlett seedlings ever produced that is truly resistant.
Studies showed that if parents that had at least some degree of resistance they
produced more resistant seedlings. Donna
