USPP32235P2 - Cherry tree named ‘Jonred I’ - Google Patents

Abstract

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, moderately vigorous, hardy, self-unfruitful, and productive tree. The fruit matures under the ecological conditions described in mid May, with first picking on May 15, 2019. The fruit is uniformly large in size, very sweet in flavor, oblate in shape, clingstone in type, very firm in texture, dark red in flesh color, very dark red in skin color, and has a medium length stem that is strongly attached to the fruit.

Description

Botanical classification: Prunus avium.

Varietal denomination: ‘JONRED I’.

BACKGROUND OF THE VARIETY

In a continuing effort to improve the quality of shipping fruits, we, the inventors, typically hybridize a large number of peach, nectarine, plum, apricot, and cherry seedlings each year. We also grow a smaller 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 ‘Jonred I’.

During a typical blooming season we isolate as seed parents individual cherry trees by covering them with screen houses. A hive of bees is placed inside each such house, and bouquets to provide pollen from different cherry trees are placed in buckets near the trees approximately every two days for the duration of the bloom. During 2008 one such house containing ‘Glenred’ (U.S. Plant Pat. No. 12,859) cherry tree was crossed by us in this manner. To pollinate this cherry, we selected bouquets from several sources of cherry trees without keeping specific written details. Upon reaching maturity the fruit from this cherry tree was harvested and the seeds were removed, cracked, stratified and germinated as a group with the label ‘Glenred House’. They were grown as seedlings on their own root in our greenhouse, and upon reaching dormancy transplanted to a cultivated area of our experimental orchard located near Le Grand, Calif. in Merced County (San Joaquin Valley). During the summer of 2013 the claimed variety was selected by us as a single tree from the group of seedlings described above. Subsequent to origination of the present variety of cherry tree, we asexually reproduced it by budding and grafting in the experimental orchard described above, and such reproductions were true to the original tree 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 its seed parent, ‘Glenred’ (U.S. Plant Pat. No. 12,859) cherry, by having a moderately vigorous tree, by blooming heavy, by being self-unfruitful, by having oval to reniform leaf glands, by being productive, and by producing medium to large cherries that are dark red in skin color, dark red in flesh color, oblate in shape, and fairly crack resistant, but is distinguished therefrom by blooming about six days later and by producing cherries that ripen about five days earlier, that are firmer in texture, that are sweeter in flavor, and that have a stronger stem attachment.

SUMMARY OF VARIETY

In summary, the present cherry variety is characterized by a medium size, moderately vigorous, hardy, self-unfruitful, and productive tree. The fruit matures under the ecological conditions described in mid May, with first picking on May 15, 2019. The fruit is uniformly large in size, very sweet in flavor, oblate in shape, clingstone in type, very firm in texture, dark red in flesh color, very dark red in skin color, and has a medium length stem that is strongly attached to the fruit.

POMOLOGICAL CHARACTERISTICS

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 19, 2019, on the original tree during its eighth growing season. All major color code designations are by reference to the Inter-Society Color Council, National Bureau of Standards. Common color names are also used occasionally.

OTHER NOTES

Although the new variety of cherry tree possesses the described characteristics under the ecological conditions at Le Grand, Calif., in the central part of the San Joaquin Valley, it is to be expected that variations in these characteristics may occur when farmed in areas with different climatic conditions, different soil types, and/or varying cultural practices.
