The present invention relates to a cherry tree, Prunus avium, and more particularly to a new and distinct variety broadly characterized by a medium size, vigorous, hardy, self-sterile, productive and regular bearing tree. The fruit matures under the ecological conditions described in late May, with first picking on May 25, 2003. The fruit is uniformly large in size, oblate in shape, clingstone in type, firm in texture, red in flesh color, and dark red in skin color. The variety was developed from an open pollinated seed from an undetermined cherry seedling.

1. A new and distinct variety of cherry tree, substantially as illustrated and described, that is most similar to the `Glenred` (U.S. Plant Pat. No. 12,859) cherry by producing cherries that are large in size, oblate in shape, firm in texture, dark red in skin color, red in flesh color, and sweet in flavor, but is distinguished therefrom and an improvement thereon by blooming about two days later, by producing cherries that ripen about ten days later, and by being a pollinator for both the `Glenred` and `Tulare` (U.S. Plant Pat. No. 6,407).

Botanical classification: Prunus avium.
In a continuing effort to improve the quality of shipping fruits, I, the inventor, typically hybridize a large number of peach, nectarine, plum, apricot, and cherry seedlings each year. I also grow a lesser number of open pollinated seeds of each of these fruits, usually to capture recessive traits. The present invention relates to a new and distinct variety of cherry tree, which has been denominated varietally as `Glenoia`. During the spring of 1993 I gathered fruit from several different unnamed cherry seedlings in my experimental orchard at Bradford Farms near La Grand, Calif. in Merced County (San Joaquin Valley). The seeds from this fruit were removed, cracked, stratified, germinated, and grown as seedlings on their own root in my greenhouse, and upon reaching dormancy transplanted to a cultivated area of my experimental orchard described above. During the fruit evaluation season of 1997 I selected several cherry trees that exhibited desirable qualities. The present variety was selected as a single tree from the group described above. Subsequent to origination of the present variety of cherry tree, I asexually reproduced it by budding and grafting in the experimental orchard descried above, and such reproduction of plant and fruit characteristics were true to the original plant in all respects. The reproduction of the variety included the use of `Colt` (unpatented) rootstock, upon which the present variety was compatible and true to type.
The present variety is most similar to the `Glenred` (U.S. Plant Pat. No. 12,859) cherry by producing cherries that are large in size, oblate in shape, firm in texture, dark red in skin color, red in flesh color, and sweet in flavor, but is distinguished therefrom and an improvement thereon by blooming about two days later, by producing cherries that ripen about ten days later, and by being a pollinator for both the `Glenred` cherry and the `Tulare` (U.S. Plant Pat. No. 6,407) cherry.
In summary, the present variety is characterized by a medium size, vigorous, hardy, self-sterile, productive and regular bearing tree. The fruit matures under the ecological conditions described in the latter part of May, with first picking on May 25, 2003. The fruit is uniformly large in size, very sweet in flavor, oblate in shape, clingstone in type, firm in texture, red in flesh color, and full red in skin color.
The accompanying photograph displays a characteristic twig bearing leaves, two fruits with the stems attached, several whole fruits detached from the stems to exhibit the skin color and form, two fruits sectioned along different planes to reveal the flesh and fibers, and two individual leaves, all typical of the subject variety.
Referring now more specifically to the pomological characteristics of this new and distinct variety of cherry tree, the following has been observed under the ecological conditions prevailing near Le Grand, Merced County (San Joaquin Valley), Calif., and was developed at the state of firm ripe on May 26, 2003, on a four year old tree on Colt rootstock.
