Cassady grape

The Cassady grape is a wild greenish-white variant of the Fox grape "Vitis labrusca". It was first described in the Interim Fruit Report of the Pennsylvania Horticultural Society in November, 1853. The first Cassady grapevine sprang up as a volunteer (unplanted) seedling in the yard of P.H. Cassady at 29 Logan Square, Philadelphia, Pennsylvania, in 1847. It did not bear fruit for five years, but when it finally did, the grapes it produced were found by Cassady to be juicy, pleasantly flavoured, and of very good quality. The Cassady grape was propagated and subsequently crossed with the better-known Concord grape to produce a new white grape variety, the Niagara grape, which is the cultivar most commonly used for the production of white grape juice in North America.

The original description of the Cassady grape was published in November 1853 on page 563 of "The Magazine of Horticulture, Botany, and All Useful Discoveries and Improvements in Rural Affairs", Vol. XIX, 1853.

A copy of the original publication was obtained from Harvard University and digitized by Google Books on 11 Jul 2007. It is available online at http://books.google.ca/books?id=OqUEAAAAYAAJ [http://books.google.ca/books?id=OqUEAAAAYAAJ] .
