Abstract

The present invention relates to a peach tree, Prunus persica, and more particularly to a new and distinct variety broadly 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, 2000. The fruit is uniformly large in size, very good in flavor, globose in shape, freestone in type, firm in texture, white in flesh color, and mostly red in skin color. The variety was developed as a first generation cross using Diamond Princess (U.S. Plant Pat. No. 7,066) yellow flesh peach as the selected seed parent and an unnamed white flesh peach as the selected pollen parent.

Description

BACKGROUND OF THE VARIETY
In a continuing effort to improve the quality of shipping fruits, I, the inventor, typically hybridize a large number of nectarine, peach, 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 ‘SNOW PRINCESS’. The present variety was hybridized by me in 1992, grown as a seedling on its own root in my greenhouse, and transplanted to a cultivated area of our experimental orchard at Bradford Farms near Le Grand, Calif. in Merced County (San Joaquin Valley). It was developed as a first generation cross using Diamond Princess (U.S. Plant Pat. No. 7,066) yellow flesh peach as the selected seed parent and an unnamed white flesh 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 Rootstock (unpatented) upon which the present variety was compatible and true to type.
The present variety is similar to its selected seed parent, Diamond Princess (U.S. Plant Pat. No. 7,066) peach, by producing freestone peaches that are globose in shape, firm in texture, and mostly red in skin color, but is distinguished therefrom and an improvement thereon by producing fruit that is white instead of yellow in flesh color, that is subacid instead of acid in flavor, that is larger in size, and that matures about two weeks later.
The present variety is most similar to White Princess (U.S. Plant Pat. No. 9,515) peach by producing freestone peaches that are white in flesh color, subacid and sweet in flavor, and mostly red in skin color, but is distinguished therefrom and an improvement thereon by blooming about ten days earlier, by having reniform instead of globose glands, and by producing fruit that is much larger in size and that matures about three weeks earlier.
DRAWING
The accompanying photograph exhibits 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, and typical leaves.
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. 24, 2000 on the original tree during its seventh growing season.
