Abstract

The present invention relates to a new and distinct variety of nectarine tree, Prunus persica, broadly characterized by a medium size, medium vigorous, hardy, self-fertile, medium productive and regular bearing tree. The variety blooms during the mid to late season and requires about 650 chilling hours. The fruit matures under the ecological conditions described in mid July, with first picking on Jul. 14, 2009. The fruit is uniformly large in size, acidic and sweet in flavor, globose in shape, clingstone in type, firm and melting in texture, mostly red in skin color, and nearly full yellow in flesh color.

Description

Botanical classification: Prunus persica.
Variety denomination: ‘GIANT BRIGHT’.
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. I also grow a lesser number of open pollinated seeds of each of these fruits, usually to capture recessive traits. The present invention relates to a new and distinct variety of nectarine tree, which has been denominated varietally as ‘GIANT BRIGHT’.
The present variety was hybridized by me in 2004 as a first generation cross using ‘Western Pride’ (U.S. Plant Pat. No. 10,888) nectarine as the selected seed parent and ‘August Fire’ (U.S. Plant Pat. No. 11,477) nectarine as the selected pollen parent. The fruit of this cross was gathered that summer, and the seeds were removed, cracked, stratified, germinated, and grown as seedlings on their own root in my greenhouse. Upon reaching dormancy the seedlings were transplanted as a group to a cultivated area of my experimental orchard located near Le Grand, Calif., in Merced County (San Joaquin Valley). During the fruit evaluation season of 2007 I selected the present variety as a single tree from the group of seedlings described above. 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’ (unpatented) rootstock upon which the present variety was compatible and true to type.
The present variety is similar to its seed parent, ‘Western Pride’ nectarine, by producing nectarines that are firm, mostly red in skin color, very large in size, and acidic in flavor, but is distinguished therefrom by producing fruit that is clingstone instead of freestone and that matures about one week earlier.
The present variety is similar to its pollen parent, ‘August Fire’ nectarine, by producing nectarines that are nearly full red in skin color, clingstone in type, firm in texture, and acidic in flavor, but is distinguished therefrom by producing fruit that is larger in size and that matures about thirty days earlier.
The present variety is most similar to ‘Summer Bright’ (U.S. Plant Pat. No. 7,049) nectarine by producing nectarines that are nearly full red in skin color, clingstone in type, acidic in flavor, and that mature in mid July, but is distinguished therefrom by producing fruit that is substantially larger in size.
SUMMARY OF VARIETY
In summary, the present variety is characterized by a medium size, medium vigorous, hardy, self-fertile, medium productive and regular bearing tree. The variety blooms during the mid to late season and requires about 650 chilling hours. The fruit matures under the ecological conditions described in mid July, with first picking on Jul. 14, 2009. The fruit is uniformly large in size, acidic and sweet in flavor, globose in shape, clingstone in type, firm and melting in texture, mostly red in skin color, and nearly full yellow in flesh color.
DRAWING
The accompanying photograph consists of four whole fruits positioned to display the characteristics of the skin color and form, one sliced fruit to reveal the flesh and stone, three insets to reveal buds and a blossom, a typical tip shoot, and characteristic 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 firm ripe on Jul. 19, 2009, on the original tree during its fifth growing season. The blossom and flower descriptions were made the previous blooming season. 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.

Other Notes
Although the new variety of nectarine tree possesses the described characteristics under the ecological conditions at Le Grand, Calif., in the central part of the San Joaquin Valley, it is to be expected that variations in these characteristics may occur when farmed in areas with different climatic conditions, different soil types, and/or varying cultural practices.
