ct you, for one reason: It is truly a
horticultural variety or clone that has just as much standing or
identity as the botanist's or forester's "variety."
MR. CALDWELL: It is a clone, and I agree with you, but a variety seems--
DR. CRANE: You are speaking from the forester's point of view.
* * * * *
MR. CALDWELL: That's why I make this other statement.
DR. CRANE: When you have got something by controlled breeding, you don't
know when you have got it. That's the whole story in a nutshell.
Now, I am going to tell you about using controlled breeding. We started
almond breeding in California, where we have one of the biggest
commercial nut industries in the country. We started almond breeding in
1920 with the best known almonds. In the 30 years of almond breeding we
have introduced two varieties. We had a panel of 125 commercial almond
growers who decided on those two varieties out of more than 20,000 known
controlled crosses that were made of trees that were grown to fruiting.
But it took a panel of 125 commercial growers to determine whether or
not these two varieties, the Jordanolo and the Harpareil, were
commercial varieties.
Those two varieties were planted. The nurserymen planted them, the
grower took them over, and they couldn't grow enough trees to supply the
demand. These two varieties have been introduced for commercial planting
now for 14 years. Of the two, one has stood the test of time, and it
stands now as probably the second most important almond variety in all
the United States, has been taken to foreign countries and is being
extensively propagated. One of them made the grade, the Jordanolo. The
Harpareil is still in the running, but it is down with the 30 or 40
varieties that are of lesser importance.
MR. CALDWELL: Can you reproduce that result?
DR. CRANE: No.
MR. CALDWELL: Then you don't know what that is or the happenstance that
got it.
DR. CRANE: Certainly, because you don't know about breeding nut trees.
MR. CALDWELL: That's what I say should be learned.
DR. CRANE: In the first place, the chromosomes are so small and there
are so many, that you can't identify them, and you can't tell which
genes, and they have got a heterozygous population, and the variety is
self-sterile and has to be cross-pollinated, so there is only one way
from a horticultural standpoint by which we can do anything, and that is
through clones.
DR. MacDANIELS: I think we
