Northern Nut Growers Association Incorporated 39th Annual Report: at Norris, Tenn. September 13-15 1948
Northern Nut Growers Association -- Periodicals; Nut trees -- Periodicals; Nuts -- Periodicals
I am one of those members who have not been able to attend annual
meetings. In the two or three years that I have been a member, I have
derived great enjoyment from reading the annual reports and receiving
information through your news bulletin.
Therefore, when I received your improved bulletin, "The Nutshell," I
felt that I and others like me should write and tell you how wonderful
it is.
There is much that I just want to "get off my chest." My past criticism
was that the organization was a bit lethargic. But nut trees are _slow_
in showing results, despite the nurserymen's attractive visions of
quick, big harvests of nuts and even timber!!! This slow patience of the
black walnut has determined the tempo of much of the membership.
+Chestnut Breeding Efforts+
My main work is to attempt to breed two types of chestnuts: (1) One that
is very productive with a low head and will bear nuts like the old
American chestnut. (2) Another that will make a good timber stick. It is
my theory that present chestnut breeders are crossing inferior material,
using any specimens that happen to be in flower at the right time as
long as they represent the species to be crossed.
Suppose they intend to cross _C. crenata_ x _C. dentata_. An average
Japanese chestnut is usually pollinated with flowers from a poor
struggling sprout on the edge of the woods that has only one thing to
recommend it. That is an early bearing characteristic which is inherent,
but which, according to experiments and observations I have tediously
carried out, _is not totally due to ringing by the blight_.
The experiment takes place and a few hybrid nuts are produced. They are
termed (_C. crenata_ x _C. dentata_). It is expected that the
characteristics of the offspring will be somewhere between those of the
two parents in blight resistance and nut size and quality. But what of
the grandparents, the many ancestors of the American chestnut sprout
that have not even the slight resistance of the sprout? Can they not
express their characteristics and hand them, down to their
grandchildren? And some individuals of _C. crenata_ are not reputed to
be so highly blight resistant.
Of course the scientists engaged in this work are men of the highest
calibre and no doubt are aware of this, but it is extremely difficult to
obtain, propagate, and care for named varieties of the finest
individuals of each chestnut species.
Apple, cherry, and other fruit breeders would not dream of crossing
common scrub cull fruit trees and expect any degree of success.
My first task when I began, three years ago, on my coppice growth 35 to
40 year old hardwood forest, was to clear a little land and to begin
planting different world species of _Castanea_.
