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, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the last week in July, with first picking on Jul. 25, 1998. The fruit is uniformly medium in size, subacidic and sweet in flavor, globose in shape, clingstone in type, very firm and crisp in texture, and full red in skin color. The variety was a first generation cross using `Red Glen` (U.S. Plant Pat. No. 7,193) nectarine as the seed parent and an unnamed white flesh nectarine seedling as the selected pollen parent.

Description

BACKGROUND OF THE VARIETY
In a continuing effort to improve the quality of fresh market and shipping fruits, we, the inventors, typically hybridize a large number of nectarine and peach seedlings each year. The present invention relates to a new and distinct variety of nectarine tree, which has been denominated varietally as `Candy Gold`. The present variety was developed by us in 1992 in a cultivated area of our experimental orchard at Bradford Farms near Le Grand, Calif. in a Merced County (San Joaquin Valley). It was a first generation cross using `Red Glen` (U.S. Plant Pat. No. 7,193) nectarine as the seed parent and an unnamed white flesh nectarine seedling as the selected pollen parent. Subsequent to origination of the present variety of nectarine tree, we asexually reproduced it by budding and grafting on Nemaguard (unpatented) rootstock, in the experimental orchard described above, and such reproduction of plant and fruit characteristics were true to the original plant in all respects.
The present variety is most similar to its seed parent, the `Red Glen`, by producing yellow flesh clingstone nectarines that are full red in skin color, very firm in texture, and that ripen the last week in July, but is distinguished therefrom and an improvement thereon by having a showy instead of nonshowy blossom, by having a bitter instead of sweet kernel, and by producing fruit that is subacid instead of acid in flavor, that is much sweeter, and that is somewhat larger in size.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying photograph exhibits four whole fruits positioned to display the characteristics of the skin color and form, a sectioned fruit sliced transverse to the suture plane to reveal the flesh and stone, and representative leaves. The colors illustrated are as close as is reasonably possible to attain in a photographic illustration of this character, however the color designations set forth in the specification should be considered to be controlling.
POMOLOGICAL CHARACTERISTICS
Referring now more specifically to the pomological characteristics of this new and distinct variety of nectarine 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 hard shipping ripe on Aug. 2, 1998.
