Dr. Moss: I am not an expert. They say an expert is someone who, the more he studies, knows less about practically nothing at all. That's a good deal my shape. I planted before the war Chinese seed in Kentucky and a good many of those put on burs in the nursery row. I gave them away in the community. Out of the whole bunch, some of them 20 feet tall, I know of one outstanding nut in that bunch and it's off by itself, apparently a self-pollinizer[16], and puts out a crop of good nuts.
Dr. Cross: I should like to ask Dr. Crane if it would not be possible to investigate the situation in China rather than wait to work this out. Certainly, the Chinese have sufficient knowledge of grafting and propagation to have been working on this long ago, and since these came from there, let's look into that phase of it.
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.
