Nectarine tree named ‘CANDYSWEET V’

The present invention relates to a new and distinct variety of nectarine tree, Prunus persica, broadly characterized by a large size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described in mid June, with first picking on Jun. 18, 2006. The fruit is uniformly medium in size, sub-acidic and very sweet in flavor, globose in shape, clingstone in type, very firm in texture, yellow in flesh color, and almost full red in skin color.

Description

Botanical classification: Prunus persica.

Variety denomination: ‘Candysweet V’.

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 ‘Candysweet V’. The present variety was hybridized by me in 2001, grown as a seedling on its own root in my greenhouse, and transplanted to a cultivated area of my experimental orchard near Le Grand, Calif., in Merced County (San Joaquin Valley).

The variety was developed as a first generation cross using ‘Spring Bright’ (U.S. Plant Pat. No. 7,507) nectarine as the selected seed parent and ‘Ruby Sweet’ (U.S. Plant Pat. No. 9,963) nectarine 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 similar to its selected seed parent, ‘Spring Bright’ nectarine, by producing fruit that is nearly globose in shape, yellow in flesh color, and full red in skin color, but is distinguished therefrom by producing nectarines that are sub-acidic instead of acidic in flavor and that mature about one week earlier.

The present variety is similar to its selected pollen parent, ‘Ruby Sweet’ nectarine, by producing nectarines that are nearly globose in shape, firm in texture, sub-acidic in flavor, and yellow in flesh color, but is distinguished therefrom by having a sweet instead of bitter kernel and by producing fruit that is sweeter in flavor and that matures about two weeks earlier.

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 mid June, with first picking on Jun. 18, 2006. The fruit is uniformly medium in size, sub-acidic and very sweet in flavor, globose in shape, clingstone in type, very firm in texture, yellow in flesh color, and almost full 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 Jun. 22, 2006, on the original tree during its fifth 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.

Claims

1. A new and distinct variety of nectarine tree, substantially as illustrated and described, that is most similar to its selected pollen parent, ‘Ruby Sweet’ (U.S. Plant Pat. No. 9,963) nectarine, by producing nectarines that are nearly globose in shape, firm in texture, sub-acidic in flavor, and yellow in flesh color, but is distinguished therefrom by having a sweet instead of bitter kernel and by producing fruit that is sweeter in flavor and that mature about two weeks earlier.
