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 June, with first picking on Jun. 2, 2003. The fruit is uniformly large in size, somewhat acidic in flavor, globose in shape, clingstone in type, very firm in texture, yellow in flesh color, and almost full red in skin color. The variety was developed as a second generation cross using ‘Red Diamond’ (U.S. Plant Pat. No. 3,165) yellow flesh nectarine as the selected seed grandparent and ‘Rose Diamond’ (U.S. Plant Pat. No. 7,421) yellow flesh nectarine as the selected pollen grandparent.

Description

Botanical classification: Prunus persica.

Variety denomination: ‘Rose 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 seedlings each year of these fruits, usually to reveal recessive characteristics. The present invention relates to a new and distinct variety of nectarine tree, which has been denominated varietally as ‘Rose Bright’. During the 1990 blooming season I emasculated an entire Red Diamond (U.S. Plant Pat. No. 3,165) nectarine tree and applied pollen from Rose Diamond (U.S. Plant Pat. No. 7,421) nectarine. I harvested the fruit from that hybridization during the following summer, germinated their seeds, and grew them in my greenhouse. Upon reaching dormancy that fall, those seedlings were transplanted as a group to my experimental orchard located near Le Grand, Calif. in Merced County (San Joaquin Valley). From that group I selected one seedling that produced yellow flesh nectarines with good qualities and designated it as “18P240”. During the spring of 1996 I gathered open pollinated seeds from “18P240”, germinated and grew them as seedlings on their own root in my greenhouse, and transplanted them the following winter into a cultivated area of my experimental orchard described above as a group labeled “18P240 (OP)”. During the spring of 1999 I selected the present variety as a single seedling from this “18P240 (OP” group. 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 selected pollen grandparent, ‘Rose Diamond’ (U.S. Plant Pat. No. 7,421) nectarine by producing nectarines that are nearly globose in shape and yellow in flesh color and that mature during the first week in June, but is distinguished therefrom by producing nectarines that are clingstone instead of freestone, larger in size, darker red in skin color and more acidic in flavor.

The present variety is similar to its selected seed grandparent, ‘Red Diamond’ (U.S. Plant Pat. No. 3,165) nectarine, by producing nectarines that are nearly globose in shape, very firm in texture, yellow in flesh color and nearly full red in skin color, but is distinguished therefrom by producing fruit that matures about thirty days earlier and that is clingstone instead of freestone.

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 June, with first picking on Jun. 2, 2003. The fruit is uniformly large in size, somewhat acidic in flavor, globose in shape, clingstone in type, very firm in texture, yellow in flesh color, and almost full red in skin color.

DRAWING

The accompanying drawing is a set of three photographs selected to display the skin color, form, and size of the fruit and leaves and one photograph depicting flower buds, open blossoms and typical petals.

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 Jun. 6, 2003, on the original tree during its seventh growing 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.
