USPP16462P2 - Peach tree named ‘Candy Princess’ - Google Patents

Abstract

The present invention relates to a peach tree, Prunus persica, and more particularly to a new and distinct variety characterized by a medium size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the third week in July, with first picking on Jul. 20, 2003. The fruit is uniformly large in size, sub-acid and sweet in flavor, globose in shape, freestone in type, firm in texture, yellow with some red streaking in flesh color, and mostly red in skin color. The variety was developed as a first generation cross using ‘Spring Bright’ (U.S. Plant Pat. No. 7,507) yellow flesh nectarine as the selected seed parent and an unnamed peach as the selected pollen parent.

Description

Latin name: Prunus persica.

Varietal denomination: ‘Candy Princess’.

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. The present invention relates to a new and distinct variety of peach tree, which has been denominated varietally as ‘Candy Princess’. The present variety was hybridized by me in 1996, grown as a seedling on its own root in my greenhouse, and transplanted to a cultivated area of my experimental orchard at Bradford Farms near Le Grand, Calif. in Merced County (San Joaquin Valley).

The variety was developed as a first generation cross using ‘Spring Bright’ (U.S. Plant Pat. No. 7,507) yellow flesh nectarine as the selected seed parent and an unnamed peach (unpatented) as the selected pollen parent. A single tree from the stated cross was selected as the claimed variety. Subsequent to origination of the present variety of nectarine 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 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 selected seed parent, ‘Spring Bright’ (U.S. Plant Pat. No. 7,507) nectarine, by producing fruit that is globose in shape, firm and crisp in texture, mostly red in skin color, and yellow in flesh color, but is very distinguished therefrom and an improvement thereon by producing fruit that is freestone instead of clingstone, that is sub-acid instead of acid in flavor, that matures about four weeks later, and that is peach instead of nectarine.

The present variety is most similar to ‘Spring Candy’ (U.S. Plant Pat. No. 14,677) peach by sharing the same parentage and by producing peaches that are freestone in type, nearly full red in skin color, yellow with some red streaking in flesh color, firm in texture, and sub-acid in flavor, but is distinguished therefrom by producing peaches that are larger in size and that mature about three weeks later.

SUMMARY OF VARIETY

In summary, the present variety is characterized by a medium size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the third week in July, with first picking on Jul. 20, 2003. The fruit is uniformly large in size, sub-acid and sweet in flavor, globose in shape, freestone in type, firm in texture, yellow with some red streaking in flesh color, and mostly red in skin color.

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. The fruit description was developed at the state of eating ripe on Jul. 28, 2003, on the original tree during its seventh growing season. The flower and bud descriptions were developed the following 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.

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.
