Title:
‘Newfane’ Sweet Cherry Tree Prunus Avium
United States Patent PP18892
Abstract:
A new and distinct variety of sweet cherry tree, Prunus avium, originating as a hybrid seedling of the cross: ‘Emperor Francis’ (non-patented)בStella’ (non-patented). This new variety is unique from its parents and other sweet cherries varieties because it is a light fleshed, light skinned variety that is suitable for brining users and is self-fertile.

What is claimed:

1. A new and distinct variety of sweet cherry tree, Prunus avium, substantially as herein shown and described, characterized as to novelty by the unique combination of self-fertile flowers, light flesh-type, with good disease tolerance and good hardiness of the tree; and possessing fresh market eating quality and shipping/handling attributes that meet grade standards for this fruit and possessing processing attributes as required for brining uses.

Description:

FIELD OF THE INVENTION

A new and distinct variety of sweet cherry tree that originated as a seedling of Prunus avium in the breeding program of Cornell University and is hereinafter referred to as ‘Newfane’ sweet cherry. This new variety is unique because this is the first self-fertile, yellow flesh-type, sweet cherry that has been made available to the commercial nursery industry of the United States of America; and the fruit has several traits that make if favorable for dual-purpose fresh market and processed uses.

SUMMARY OF THE INVENTION

This new and distinct variety of sweet cherry was discovered in 1984 by Roger D. Way (retired), a plant breeder at the New York State Agricultural Experiment Station, Geneva, N.Y., a research unit of Cornell University, hereinafter referred to as Geneva Experiment Station. By breeding methodology convention at the Geneva Experiment Station it was designated as NY 13688. This selection was initially assigned Experiment Station Breeding Record Number 75.304, a hybrid population of trees that resulted from hybridizing the varieties ‘Emperor Francis’ (non-patented)בStella’ (non-patented) in 1975, and this seedling was designated as NY 13688 when it was planted in 1976 as part of a population of 433 siblings possessing the same parentage. The orchard location where the seedling was grown and first noticed was designated as Crittenden Farm, Field Number 30, Row 5, Tree 010. This seedling was first noticed because in 1984 Cornell scientists purposely bagged branches to isolate the flowers from pollinating insect visits and it cropped heavily inside the bag, proving that it was self-fertile; and the fruit were light in flesh color and possessed a ninety percent red blush. This skin coloration was considered as uncommon and potentially valuable for fresh market appeal of the fruit. The new variety has been propagated on Mazzard seedling (non-patented), Mahaleb seedling (non-patented), ‘Gisela 6’ (U.S. Plant Pat. No. 8,954), ‘MxM 2’ (U.S. Plant Pat. No. 8,194) and ‘MxM 60’ (U.S. Plant Pat. No. 8,132) rootstocks and remains true to the description herein.

The new variety differs from its parents in the following. Unlike ‘Emperor Francis’ (not patented) the new variety is self fertile whereas ‘Emperor Francis’ (non patented) requires another variety as a pollen source. Unlike ‘Stella’ (non patented) the new variety is yellow fleshed with skin coloration of a red blush over yellow where “Stella” (non patented) has dark burgundy-black skin and flesh.
