Nectarine tree named ‘LATE BRIGHT’

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 in early to mid September, with first picking on Sep. 7, 2005. The fruit is very large in size, acidic and sweet in flavor, globose in shape, clingstone in type, firm in texture, yellow with red bleeding in flesh color, and about fifty percent red in skin color. The variety was developed as a first generation cross using ‘September Red’ (U.S. Plant Pat. No. 5,664) nectarine as the selected seed parent and an unnamed nectarine (unpatented) as the selected pollen parent.

Description

Latin name: Prunus persica.

Varietal denomination: ‘LATE 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. The present invention relates to a new and distinct variety of nectarine tree, which has been denominated varietally as ‘LATE BRIGHT’. The present variety was hybridized by me in 1998, 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 ‘September Red’ (U.S. Plant Pat. No. 5,664) nectarine as the selected seed parent and an unnamed nectarine (unpatented) as the selected pollen parent. A single tree from the stated cross was selected as the claimed variety. 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 most similar to its selected seed parent, ‘September Red’ (U.S. Plant Pat. No. 5,664) nectarine by producing late maturing clingstone nectarines that are red and yellow in skin color, yellow with red bleeding in flesh color, acidic and sweet in flavor, and nearly globose in shape but is distinguished therefrom by having a sweet instead of bitter kernel and by producing nectarines that are much larger in size.

SUMMARY OF VARIETY

In summary, the present variety is characterized by a large size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described in early to mid September, with first picking on Sep. 7, 2005. The fruit is very large in size, acidic and sweet in flavor, globose in shape, clingstone in type, firm in texture, yellow with red bleeding in flesh color, and about fifty percent red in skin color.

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 Sep. 10, 2005, on the first multiplied tree on Nemaguard (unpatented) rootstock during its fourth growing season.

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.
