injury of
wood. Varieties in which more than 50 per cent of the wood was killed
are Nottingham, Early Prolific, Garibaldi, Princess Royal, Webb's Prize
Cob, Bandnuss, Grosse Kugelnuss, Jeeves Samling, Kaiserin Eugenie,
Multiflora, Kurzhullige Zellernuss, Lange von Downton, and the Corylus
rostrata previously mentioned.

Varieties experiencing from 20 to 50 per cent of wood killing were
Barcelona, Red Aveline, Montebello, Berger's Zellernuss, Einzeltragende
Kegelformige, Heynick's Zellernuss, Prolifique a Coque serre, Sickler's
Zellernuss, Voile Zellernuss, and Russ.

In the following varieties from 5 to 20 per cent of the wood was
winter-killed: Minna, Bollwiller, Duchess of Edinboro, Pearson's
Prolific, The Shah, Barr's Zellernuss, Kunzemuller's Zellernuss,
Liegel's Zellernuss, Romische Nuss, Schlesierin, Truchsess Zellernuss,
Vollkugel and Littlepage.

Varieties which are not injured at all or less than five per cent were
Clackamas, Cosford, Daviana, Early Globe, English Cluster, Kentish Cob,
Fertile de Coutard, Italian Red, Medium Long, Oregon, Purple Aveline,
Red Lambert, White Aveline, White Lambert, D'Alger, Cannon Ball, Duke of
Edinburgh, Kentish filbert, Prolific Closehead, Red Skinned, Eckige
Barcelonaer, Kadetten Zellernuss, Ludolph's Zellernuss, Luisen's
Zellernuss, Kruse, Neue Riesennuss and Rush and Winkler.

It is evident from this data that although many filbert varieties are
subject to serious winter injury, there are still a number to choose
from that are sufficiently hardy under western New York conditions.

Variety Notes

The Station variety collection has grown considerably since I discussed
filberts before you in 1929. At that time the collection consisted of 28
varieties; today there are under test at Geneva 99 varieties of Corylus
avellana, five varieties of Corylus americana, five Jones seedlings, and
six species of Corylus, or a total of 115 forms.

Later observations on the original orchard have indicated that the
original variety recommendations should be modified. Certain varieties
imported from Europe and renamed, or were misnamed when imported, and
that have been disseminated by nurseries are apparently identical with
certain German varieties recently imported by the Geneva Station.
Preliminary observations indicate that some of these recently imported
German sorts are worthy of further attention.

Barcelona which was the most productive variety during the first few
years has b
