Dr. Crane: I did investigate the situation in China when I was there.
Unfortunately in China, although it is one of our oldest countries and
longest civilizations, they don't do much grafting. They grow their
trees from seed, but they have certain seed trees that they select their
seed from, and within a community, within a valley, you will have a
certain type of chestnut. They call them varieties. They are not
varieties. That's the situation. Most all of them are different, but
they have accomplished the fixing of certain characteristics.
Now, in South China the nuts are larger in size, they are stronger
growing trees than they are in the North. I think that we will find that
that's the situation in this country. The Chinese chestnut is one that
does have a high heat requirement, just like pecan, and grown under
conditions where they have high heat they are bigger in size and make
more growth and probably they come into bearing sooner.
But I didn't see anything grafted in China, and I was all over the
country from the most northern parts to the most southern parts where
chestnuts are produced. I could make a lot of observations myself, but I
had to talk through interpreters, and sometimes you couldn't tell what
the interpreter meant. But as near as I could tell, they were all
seedlings. When he would tell me there was such-and-such a variety, I
would ask him what it meant in English. He didn't know. When I found
how they were propagated I found they planted the seed. When I found
where they got the seed it was from a certain seed tree.
So we have within the valleys what they call varieties, but they are not
varieties, only seedlings grown from certain seed trees.
Now, with the Japanese, on the other hand, the situation is different,
because they propagated by budding and by grafting. I got a number of
the Japanese publications of propagation methods and their stocks, and
so forth, translated into English, and their problems are just the same
as we are going through right here now. They propagate true varieties by
asexual methods, but the Chinese do not to any extent at all.
Dr. Cross: Have the Russians got any?
A Member: That's the question I ask. Do we have any seed trees in this
country that are better than other seed trees?
Mr. Porter: Could the gentleman tell us whether the Chinese graft _any_
chestnuts.
Dr. Crane: Yes, they do so, I was told.
Mr. Porter: Well, the industry spends a lot of money, so do other
people, and so on, in a proper way to investigate that. Why don't you
find out where in that country they have been doing it?
Dr. Crane: I didn't see any grafted chestnut trees over there.
A Member: You said they grafted, and then you say, "I didn't see any."
