On days of moderate temperature I wet these bags thoroughly with water once a day but on very hot or windy days I often wet them twice. This keeps the nuts moist most of the time and lowers the temperature considerably from the evaporation. In this way I can keep the nuts days and days and even weeks with very little change except a slight drying. If any spoiled nuts were missed by the water these too will show up in about 10 days with specks of white mold and can be eliminated. The other nuts seem to be as good as the day they were gathered. I only use this to keep them temperarily (as it is some trouble to wet them) and mostly for the eating nuts until I can take them to market or put them on cold storage (30° to 35°F.) If I attempt to hold seed nuts about a week or more I pack in damp sphagnum in crates and keep these under the shade tree with excellent results. This year I used green sphagnum with all its water and the nuts seemed to keep well in it. Some nuts have been in damp sphagnum for over 5 weeks now and are in excellent shape except for a few that spoiled at first (which I am quite sure were bad to begin with). If too much water is used some nuts will begin sprouting but it is surprising how much they can stand and show no tendency to sour.
I am of the opinion that the chestnuts in my section get ripe prematurely and that at a time when we often have our hottest and dryest weather. These nuts seem to need a period to continue their ripening under cool moist conditions which the wet sack treatment gives (or the damp sphagnum.) Even if this is not the case I have had splendid results with it whereas before I began using this method with lots of water I often became so discouraged that I thought I would have to abandon trying to put my chestnuts on the market. Now if I can get them gathered promptly I have little trouble holding them until I am ready to dispose of them.
I failed to tell you that the bad feature about my ML No. 2 tree which produced the 150 pounds of nuts is its early ripening period (the latter part of August and first part of September) which causes some of the nuts to be spoiled almost when they fall. A few hours of too hot sun seems to start the spoiling process. The tree has no other objectionable features except the nuts are only small to medium in size but nearly every one falls freely from the burs. [Nuts about 70 to the pound.—Ed.]
Some Results with Filbert Breeding at Geneva, N.Y.[6]
GEORGE L. SLATE New York (Geneva) Agricultural Experiment Station
This paper reports the results of attempts to improve filberts by hybridization at the Experiment Station at Geneva, N. Y. The filbert project was started at Geneva in the spring of 1925 when a collection of varieties from American sources was established. In later years additional varieties from European and other sources were added until about 120 were under test. As soon as the varieties had fruited for several years it became evident that many of them were inferior and not adapted to New York conditions. A few exhibited considerable merit and the range of characteristics in the different varieties indicated that it might be worth while to start a filbert breeding project with the object of combining the desirable characteristics of the better sorts.
It was decided first to cross Rush, a selected form of Corylus americana, with the best varieties of Corylus Avellana, Rush contributing the hardiness of the native hazel, possible resistance to filbert blight, and the hybrid vigor that sometimes results from the crossing of two species. The European filberts were expected to furnish large-sized nuts as well as dessert and cracking quality.
The first crosses were made in 1930 when two trees of the Rush variety growing on Dr. MacDaniels' place in Ithaca were pollinated with pollen of several varieties of Corylus Avellana that was brought from Geneva. Additional crosses were made at Ithaca in 1931 and 1933. In 1932 the pollinations were made at Geneva, using a Barcelona tree covered with a tightly woven cloth. No pollinations have been made since 1933.
In the spring of 1932, 535 seedlings were received from Willard G. Bixby, of Baldwin, Long Island, N. Y., which had resulted from crosses made by C. A. Reed of the United States Department of Agriculture, at Baldwin. Including these U.S.D.A. seedlings and those resulting from the breeding work at Geneva, 1,999 seedlings have fruited.
