Abstract

The present invention relates to a nectarine tree and more particularly to a new and distinct variety broadly characterized by a large size, vigorous, productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the third week in July, with first picking on Jul. 22, 1994. The fruit is uniformly large in size, non-acidic in flavor, globose in shape, clingstone in type, very firm in texture, and nearly full red in skin color. The variety was 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 seedling as the selected pollen parent, which was previously developed by crossing August Red (U.S. Plant Pat. No. 6,363) nectarine by Bradcrim (U.S. Plant Pat. No. 8,461) nectarine.

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 "Bright Pearl". The present variety was developed by us in 1991 in a cultivated area of our experimental orchard at Bradford Farms near Le Grand, Calif. in 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. This unnamed pollen parent was previously developed by crossing August Red (U.S. Plant Pat. No. 6,363) nectarine by Bradcrim (U.S. Plant Pat. No. 8,461) nectarine. Subsequent to origination of the present variety of nectarine tree, we asexually reproduced it by budding and grafting, and such reproduction of plant and fruit characteristics were true to the original plant in all respects.
The fruit produced by the present variety is most similar to its pollen grandparent, the Bradcrim (U.S. Plant Pat. No. 8,461), by producing white flesh nectarines that are non-acidic in flavor and virtually free from red texture bleeding, but is distinguished therefrom and an improvement thereon by producing fruit that ripens twenty-three days later, that is larger in size, that is fuller red in skin color, that is much firmer in texture, that is much sweeter in flavor, and that is clingstone instead of freestone.
The present variety is similar to both its seed parent, Red Glen (U.S. Plant Pat. No. 7,193) and its pollen grandparent, August Red (U.S. Plant Pat. No. 6,363), by producing nectarines that are large sized, clingstone, very firm, and nearly full red in skin color, but is very distinguished from both by producing fruit that is white flesh instead of yellow flesh, and that is non-acidic in flavor instead of acidic.
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, a stone, and typical leaves.
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 ripe on Jul. 27, 1994. 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.
