Abstract
The presently described apple tree originated as a generic bud sport on a Hannaford Spur Granny Smith apple tree (U.S. Plant Pat. No. 3,453) in the Calvin L. Cooper orchard located in Brewster, Wash. The new apple tree and its fruit are characterized by the desirable properties which characterize the parent Hannaford Granny Smith. In addition, it is characterized by significantly increased bloom set, by significantly higher setting of double and triple apple clusters, by sharply increased productivity, and by materially reduced internodal distances on the terminal growth of its branches.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.

A new and distinct variety of Granny Smith apple tree similar to the parent Hannaford strain Granny Smith apple tree, but characterized by significantly increased bloom set, by significantly higher setting of double and triple apple clusters, by sharply increased productivity, and by materially reduced internodal distances on the terminal growths of its branches.
