Then out of that variety test a grading project developed. We got our
start from about 500 seedlings that Clarence Reed sent us in the early
'30's. We made crosses there at Geneva, using the Rush variety of
_Corylus americana_ as the seed parent in many cases. We also made some
crosses between _Corylus avellana_ varieties, and with these seedlings
from Mr. Reed and seedlings of our own crossing, we have grown about
2,000 filbert seedlings there at Geneva. These have all been evaluated
and discarded, except possibly 30 or 35 selections still on hand, some
of them being propagated for a second test planting. Stock of one or two
has been turned over to the Fruit Testing Association for increase and
eventual naming and introduction.
The work of the United States Department of Agriculture was along
similar lines. Mr. Reed did not send us all of his seedlings. A number
of them were fruited at Beltsville, and from that work at Beltsville I
believe two varieties have been named, Reed and Potomac. I am not sure
whether they are available yet from commercial sources.
MR. MCDANIEL: Two of them are.
MR. SLATE: Mr. Graham of Ithaca, a long-time member of this Association
and very much interested in filberts, had also made some crosses and
raised several hundred seedlings. He used the Winkler variety as a seed
parent. I believe he raised some seedlings of the Jones hybrids, which
would make that material second generation stock from the original cross
between Rush and the _avellana_ varieties.
Mr. Graham's planting was in rather a cold area; he had considerable
winter killing. Eventually filbert blight got into his planting, and it
really cleaned house. There were a very few seedlings in his planting
which remained free of filbert blight. I think it is a fairly safe guess
to say that they were probably very resistant to blight. So far these
have not been propagated to any extent.
There are a few cultural problems. The ones that we have encountered at
Geneva have been winter injury, particularly of the catkins, and also
some of them have not been as hardy in wood as we would like. We have
had no trouble with filbert blight, presumably because we are isolated
from the wild hazel, which harbors this blight. Dr. MacDaniels has had
trouble with his planting at Ithaca with filbert mite.
With this introduction, which is mostly varieties and breeding, because
that seems to be my interest, I'd like to call on some members of the
panel to get their experiences. Mr. Snyder raises nut trees in Iowa
where winter injury is probably much more serious than we have at
Geneva. At Geneva we have a fairly respectable climate and can get a
crop of peaches about nine years out of ten. In Iowa they have a lot
more sunshine, and I think probably sharper drops of temperature than we
have at Geneva. I'd like to have Mr. Snyder tell us what his experiences
have been with filbert varieties.
