A letter from H. P. Olmo, Professor of Viticulture, University of California, Davis, Calif. to Wilbur P. McDonald, M. D. dated March 4, 1971. It is on the University of California, Davis letterhead.Context
Dear Dr. McDonald:
Dr. Cook has come across a rather dusty letter from his files in which, on rereading, he calls attention to the fact you are interested in obtaining cuttings of the variety T8-43. We are pacing a few cuttings of this variety in storage and will be able to send them as soon as you are ready to receive them. T8-43 is a white wine grape giving a highly aromatic wine and is a hybrid of F2-35 x Seibel 7053. The F2-35 if vinifera from a cross of Carignane x Cabernet Sauvignon. Dr. Cook also asked me to comment on the winter hardiness of some of the vinifera varieties.
In New York State, from my observations, the Ruby Cabernet is not necessarily more winter hardy than the Pinot Chardonnay, but for some strange reason more hardy than the Cabernet Sauvignon parent. Amongst the vinifera, the Aligote, Gamay, Pinot Chardonnay, Pinot noir and White Riesling are perhaps the most winter hardy in descending order as given. I do not know of any adequate test of hardiness for
Sereksiya, the Russian vinifera. Some times the Russians' claims are exaggerated and need verification. In general, none of the vinifera varieties are considered as winter hardy as the North American species such as riparia, rupestris, etc.
Sincerely yours,Lexicon
