Nectarine tree named ‘SUGARRED I’

Abstract

The present invention relates to a new and distinct variety of nectarine tree, Prunus persica, broadly characterized by a medium size, moderately 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. 19, 2006. The fruit is uniformly large in size, mildly acidic and sweet in flavor, globose in shape, clingstone in type, very firm in texture, yellow with strong red bleeding in flesh color, and full red in skin color.

Description

Botanical classification: Prunus persica.

Variety denomination: ‘Sugarred I’.

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 ‘SUGARRED I’. The present variety was hybridized by me in 2000, grown as a seedling on its own root in my greenhouse, and transplanted to a cultivated area of my experimental orchard located 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 an unnamed nectarine seedling 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, ‘Spring Bright’ nectarine, by producing nectarines that are nearly globose in shape, acidic and sweet in flavor, and full red in skin color, but is distinguished therefrom by producing nectarines that are yellow with much more red bleeding in flesh color, that are larger in size, and that mature about five days earlier.

SUMMARY OF VARIETY

In summary, the present variety is characterized by a medium size, moderately 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. 19, 2006. The fruit is uniformly large in size, mildly acidic and sweet in flavor, globose in shape, clingstone in type, very firm in texture, yellow with strong red bleeding in flesh color, and 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. 23, 2006, on the original tree during its sixth 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.

Claims

1. A new and distinct variety of nectarine tree, substantially as illustrated and described, that is most similar to its selected seed parent, ‘Spring Bright’ (U.S. Plant Pat. No. 7,507) nectarine, by producing nectarines that are nearly globose in shape, acidic and sweet in flavor, and full red in skin color, but is distinguished therefrom by producing nectarines that are yellow with much more red bleeding in flesh color, that are larger in size, and that mature about five days earlier.
