USPP28996P2 - Peach tree named ‘JULY PRINCESS’ - Google Patents

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 variety blooms during the early to mid blooming season and requires about 500 chilling hours. The fruit matures under the ecological conditions, described in early to mid July with the first picking on Jul. 3, 2016. The fruit is uniform, medium in size, fairly globose in shape, freestone in type, firm in texture, yellow in flesh color, mostly red in skin color, and moderately acidic in flavor.

Description

Botanical classification: Prunus persica.

Variety denomination: ‘JULY PRINCESS’.

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 peach tree, which has been denominated varietally as ‘JULY PRINCESS’.

The present variety was hybridized by us in 2000 as a first generation cross using “43P318” (unpatented) peach as the selected seed parent and ‘Snow Princess’(U.S. Plant Pat. No. 12,570) peach as the selected pollen parent. Upon reaching maturity the fruit from this cross was harvested, and the seeds were removed, cracked, stratified, germinated, and grown as seedlings on their own root in our greenhouse. Upon reaching dormancy the seedlings were transplanted as a group to a cultivated area of our experimental orchard located near Le Grand, Calif., in Merced County (San Joaquin Valley). During the fruit evaluation season of 2006 we selected the present variety as a single tree from the group of seedlings described above. Subsequent to origination of the present variety of peach 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 ‘Nemaguard’ (unpatented) rootstock upon which the present variety was compatible and true to type.

The present variety is similar to its seed parent, ‘43P318’ peach (unpatented), by having a vigorous tree, by being self-fertile, and by producing peaches that are freestone in type, mostly red in skin color, and yellow in flesh color, but is quite distinguished therefrom by blooming much earlier, by requiring much less chilling, and by producing peaches that mature about thirty days earlier.

The present variety is similar to its pollen parent, ‘Snow Princess’ peach (U.S. Plant Pat. No. 12,570), by having a vigorous tree with large blossoms, by being self-fertile, and by producing freestone peaches that are mostly red to pink in skin color, globose in shape, and firm in texture, but is distinguished therefrom by producing fruit that is acidic instead of sub-acidic in flavor, that is yellow instead of white in flesh color, and that matures about twelve days earlier.

The present variety is most similar to ‘Red Princess’ peach (U.S. Plant Pat. No. 24,729) by having large blossoms, by being self-fertile, and by producing peaches that are mostly red in skin color, yellow in flesh color, fairly globose in shape, lightly acidic in flavor, and firm in texture, but is distinguished therefrom by requiring less chilling hours, and by producing fruit that is freestone instead of clingstone in type, that is somewhat smaller in size, that has a bitter instead of sweet kernel, and that ripens about eighteen days later.

SUMMARY OF VARIETY

In summary, the present peach variety is characterized by a large size, vigorous, hardy, self-fertile, productive and regular bearing tree. The variety blooms during the early to mid blooming season and requires about 500 chilling hours. The fruit matures under the ecological conditions described in early to mid July with the first picking on Jul. 3, 2016. The fruit is uniform, medium in size, globose in shape, freestone in type, firm in texture, yellow in flesh color, mostly red in skin color, and moderately acidic in flavor.

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 Jul. 7, 2016, on the original tree its sixteenth growing season. The blossom and flower descriptions were made the previous blooming 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.

It is to be noted that the 2016 fruit season in California was very warm during the spring and the ripening times of almost all varieties were about two weeks earlier than other years.

OTHER NOTES

Although the new variety of peach 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.

Claims (1)

We claim:

1. A new and distinct variety of peach tree, substantially as illustrated and described, that is most similar to ‘Red Princess’ peach (U.S. Plant Pat. No. 24,729) by having large blossoms, by being self-fertile, and by producing peaches that are mostly red in skin color, yellow in flesh color, fairly globose in shape, acidic in flavor, and firm in texture, but is distinguished therefrom by requiring less chilling hours, and by producing fruit that is freestone instead of clingstone in type, that is somewhat smaller in size, that has a bitter instead of sweet kernel, and that ripens about eighteen days later.
