| Abstract: |
The present invention relates to a new and distinct variety of peach tree, Prunus persica, broadly characterized by a large size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described in the early part of June, with first picking on Jun. 7, 2006. The fruit is uniformly large in size, sub-acidic and sweet in flavor, globose to oblate in shape, clingstone in type, firm in texture, yellow in flesh color, and fully red in skin color. |
| Claim: |
I claim:
1. A new and distinct variety of peach tree, substantially as illustrated and described, that is most similar to `SPRING CANDY` (U.S. Plant Pat. No. 14,677) peach by producing peachesthat are firm in texture, yellow in flesh color, sub-acid in flavor, and mostly red in skin color, but is distinguished therefrom by blooming later, by requiring more chilling hours, and by producing fruit that is clingstone instead of freestone in type,that is sweeter in taste, and that matures about twelve days earlier. |
| Description: |
Botanical classification: Prunus persica.
Variety denomination: `SUGARPEACH III`.
BACKGROUND OF THE VARIETY
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 ofeach of these fruits, usually to capture recessive traits. The present invention relates to a new and distinct variety of peach tree, which has been denominated varietally as `SUGARPEACH III`.
During the spring of 1998 I gathered fruit from several different unnamed seedlings in my experimental orchard located near Le Grand, Calif., in Merced County (San Joaquin Valley). One particular group of peaches was yellow in flesh color,clingstone in type, and sub-acid in flavor, and was thus designated as "YPCSA (OP)". The seeds from this fruit were removed, cracked, stratified, germinated, and grown as seedlings on their own root in my greenhouse. Upon reaching dormancy that fall, Itransplanted them to a cultivated area in the experimental orchard described above. During the fruit evaluation season of 2001 I selected the claimed variety as a single tree from the group of "YPCSA (OP)" described above. Subsequent to origination ofthe present variety of peach tree, I asexually reproduced it by budding and grafting in the experimental orchard described above, and such reproduction of plant and fruit characteristics were true to the original plant in all respects. The reproductionof the variety included the use of `Nemaguard` (unpatented) rootstock upon which the present variety was compatible and true to type.
The present variety is most similar to `SPRING CANDY` (U.S. Plant Pat. No. 14,677) peach by producing peaches that are firm in texture, yellow in flesh color, sub-acid in flavor, and mostly red in skin color, but is distinguished therefrom byblooming later, by requiring more chilling hours, and by producing fruit that is clingstone instead of freestone in type, that is sweeter in taste, and that matures about twelve days earlier.
SUMMARY OF VARIETY
In summary, the present variety is characterized by a large size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described in the early part of June, with first picking onJun. 7, 2006. The fruit is uniformly large in size, sub-acidic and sweet in flavor, globose to oblate in shape, clingstone in type, firm in texture, yellow in flesh color, and full red in skin color.
DRAWING
The accompanying photograph consists of four whole fruits positioned to display the characteristics of the skin color and form, one fruit divided transversely to the suture plane to reveal the flesh and stone, a clean freshly removed stone, twoinsets to reveal buds and a blossom, one entire leaf, and a typical tip shoot.
POMOLOGICAL CHARACTERISTICS
Referring now more specifically to the pomological characteristics of this new and distinct variety of peach 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 Jun. 12, 2006, on the original tree during its eighth growing season.
