Peach tree named ‘Spring Candy’

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 last week in June, with first picking on Jun. 25, 2002. 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

Botanical classification: Prunus persica.

Variety denomination: ‘Bright Princess’.

CROSS REFERENCE TO RELATED APPLICATIONS

This case is related to co-pending U.S. Plant Patent Application filed concurrently as Peach Tree Named ‘Bright 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 ‘Spring Candy’. 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 as the selected pollen parent. Subsequent to origination of the 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 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, yellow in flesh color, and that ripen in the latter part of June, but is very distinguished therefrom by producing fruit that is freestone instead of clingstone, that is sub-acid instead of acid in flavor, and that is peach instead of nectarine in type.

The present variety is similar to the cross referenced ‘Bright Princess’ peach by sharing the same parentage and by producing peaches that are freestone in type, nearly full red in skin color, yellow in flesh color, and firm in texture, but differs significantly by producing peaches that have sub-acidic flavor instead of the classical acidic peach flavor, that have much more red streaking around the stone, that mature about 3 days later, and that have a bitter kernel instead of sweet.

The present variety is most similar to ‘Diamond Princess’ (U.S. Plant Pat. No. 7,066) peach by producing fruit that is yellow in flesh color, nearly full red in skin color, and freestone in type, but is distinguished therefrom and an improvement thereon by blooming about ten days earlier and by producing fruit that is firmer in texture, larger in size, sub-acid instead of acid in flavor, and matures about twelve days earlier.

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 last week in June, with first picking on Jun. 25, 2002. 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.

Other Notes
