The next item will be our discussion of filbert varieties and their culture. Mildred Jones, who was to be here, could not come. She telephoned the last minute that she was ill and could not be with us. I have asked George Slate to be the moderator in the discussion, with his panel, D. C. Snyder, Raymond Silvis, A. M. Whitford, Louis Gerardi and H. F. Stoke.
MR. SLATE: I just learned when I arrived here that I was to be on this discussion group, and I learned a few minutes ago that I was to lead it, so I can assure you that this is wholly unrehearsed, and I may have to flounder around a bit before we get things running smoothly.
I thought I might review the variety situation rather briefly. We have done quite a lot of variety testing of filberts at Geneva; in fact, about the only nut cultural work we have done at Geneva has been the filbert project. We started out with about 25 or 30 varieties that we secured from American nurseries, many of them from a firm in Rochester which imported them from Germany. Later we added varieties from England, France and Germany. I picked up nearly all the varieties that I could locate until we had about 120 varieties growing there at Geneva. These were there for some years, and it became evident that many of them were not of great value. Then we had a hard winter in 1933 and 1934, and although it did not kill the trees, most of them were blackhearted and began going back soon after that. However, I felt at that time that I knew enough about the varieties to discard most of them. Many of them were discarded because they had poor nuts, many of them were unproductive, and many of them lacked hardiness of catkins. I laid a great deal of emphasis on the hardiness of catkins in testing the varieties.
Out of that variety test were three varieties which we considered to be most satisfactory of the lot. These were Cosford, an English variety, rather a small nut but very thin-shelled. The catkins were hardy and one of the heavier croppers of the lot. Medium Long, a nut which I believe originated as a seedling in Rochester, was another one, and Italian Red, which later proved to be Gustav's Zellernuss, a German variety, was another.
As a result of that variety test it became evident that varieties from Germany, many of which originated in the colder portions of Germany and Northern Germany, were distinctly more hardy than the varieties that we got from French sources and English sources. In some of the proceedings of the Association published during the '30's I have reported on the different varieties and their hardiness and those varieties that I thought were most valuable. I don't recall the names of many of those German varieties. These three varieties which we consider the best of the lot were turned over to the New York Fruit Testing Association to propagate and distribute, because they were not available from American nurseries. I am not sure how many of them were available from other sources, but they are still available from the Fruit Testing Association.
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.
