+The Filbert+
Mr. Jones had a tree or two of the Turkish filbert, a species sometimes reaching a height of 60 feet and attaining a trunk diameter of three feet or more. Bixby found the species hardy in central New Hampshire. Mr. Jones obtained his seed from three trees in Highland Park, Rochester, New York, which are believed to be the oldest in the country. In some years, the Rochester trees bear freely, while in others there is not a nut. This is a valuable ornamental species, as it is green from early spring till the last thing in fall; specimens must be selected for such use, as often the trees are unshapely. Like all filberts, they are subject to Japanese beetle attack and must be sprayed or otherwise protected in beetle infested zones. Filbert foliage may be destroyed by these insects as many as three times in a summer and the trees die down to the ground. The nuts are too small to be of value; but the wood is white, very hard, and makes good turned articles.
+His Greatest Contribution+
It was with the filbert that Mr. Jones made his greatest contribution to nut culture. In 1917 he tried crossing European varieties with pollen of the native Rush. There were no results, and he tried again in 1918 with no better luck. In 1919 he reversed the order of crossing and nearly every nut set. He had discovered that native pollen was not effective on European stigmas, but that the reciprocal cross worked. By 1924 he had a fine lot of fruiting plants. The great majority were of no value, but his No. 200 apparently was well worth while. It was named Bixby in 1937, four years after another seedling, No. 91, had been named Buchanan. The explanation of this belated selection is that the soil about the Bixby tree had so eroded that the tree was starved for a time; but with a couple of years of heavy application of stable manure, it came back, so much so that it is now considered the better of the two. Both are rather small as compared with the large filberts of the Pacific Northwest; but when fully mature, they are sweet and agreeable.
After Mr. Jones was gone, the place was managed by his daughter, Miss Mildred Jones. She kept plants of her father's filbert varieties and the best of the crosses. The latter are now called the Mildred filberts, a name applied in Standardized Plant Names to the entire group of crosses between Rush American and any European filbert. Mr. Jones hoped to have these called after himself but there was an old variety of Jones "hazel" and so his own name could not be used. He once sent specimens to Dr. C. S. Sargent of Arnold Arboretum and somehow gained the impression that the name Jones was given to the cross. Later, however, Sargent's successor, Mr. Alfred Rehder wrote that Sargent had not used the name in either correspondence or on specimens placed in the herbarium.
The example of Mr. Jones in breeding filberts has since been followed by others, as the Department of Agriculture, the New York State Agricultural Experiment Station at Geneva, and. Mr. Carl Weschcke of St. Paul, Minnesota. The last has copyrighted his crosses under the designation "hazilbert," which is a good name; but with the issue of Standardized Plant Names in 1942, the name "hazel" was dropped for all members of the family. For a time, an effort was made to distinguish between the two by calling small-fruited ones "hazels" and those with large fruits "filberts," but there is not exact dividing line and so now all are called filberts.
Buchanan and Bixby are the only varieties of Mildred filberts thus far fully released by anyone and although neither variety is entirely hardy in the northernmost parts of the country, they do well as far south as eastern Tennessee. The nuts of both are too small to compete in the market with the large filberts of Oregon and Washington, but that is not the purpose for which they have been bred. It is for home planting, a use for which they are admirably adapted. Neither variety should be judged until after they have cured fully, at least a month or more. Then the flavor is excellent.
Of the various introductions made by Mr. Jones, the ones most likely to endure are the Ohio black walnut, the Glover shagbark hickory, and the Mildred filberts. The first has already lasted 32 years; the second 30 years; and the Mildred filberts are only nicely started.[24]
