Abstract

The present invention relates to a nectarine tree, Prunus persica, and more particularly to a new and distinct variety broadly characterized by a large size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the first week in July, with first picking on Jul. 6, 2001. The fruit is uniformly large in size, subacid in flavor, globose in shape, freestone in type, firm in texture, yellow in flesh color, and red in skin color. The variety was developed as a first generation cross using ‘Red Glen’ (U.S. Plant Pat. No. 7,193) yellow flesh nectarine as the selected seed parent and an unnamed white flesh nectarine as the selected pollen parent.

Description

CROSS REFERENCE TO RELATED APPLICATIONS
This case is related to co-pending U.S. Plant patent application Ser. No. 10/014,020, filed Dec. 13, 2001, drawn to ‘SWEET PEARL’ nectarine.
BOTANICAL CLASSIFICATION
Prunus persica.
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 nectarine tree, which has been denominated varietally as ‘SWEET SURPRISE’. 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 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 ‘Red Glen’ (U.S. Plant Pat. No. 7,193) yellow flesh nectarine as the selected seed parent and an unnamed white flesh nectarine as the selected pollen parent. 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’ rootstock (unpatented) upon which the present variety was compatible and true to type.
The present variety is similar to its selected seed parent, ‘Red Glen’ (U.S. Plant Pat. No. 7,193) nectarine, by producing nectarines that are globose in shape, firm in texture, and almost fully red in skin color, but is distinguished therefrom and an improvement thereon by producing fruit that is freestone instead of clingstone, that is subacid instead of acid in flavor, and that matures about three weeks earlier.
The present variety is most similar to ‘Grand Sweet’ (U.S. Plant Pat. No. 11,954) nectarine by producing nectarines that are subacid and sweet in flavor and full red in skin color, but is distinguished therefrom and an improvement thereon by producing fruit that is freestone instead of clingstone, that matures about two weeks earlier, and that has a sweet instead of bitter tasting kernel.
DRAWING
The accompanying photograph exhibits four whole fruits positioned to display the characteristics of the skin color and form, one fruit divided around the suture plane to reveal the flesh and stone, and typical leaves.
