Nectarine tree named ‘Red Rage I’

Abstract

The present invention relates to a new and distinct variety of nectarine tree, Prunus persica, broadly characterized by a medium size, vigorous, hardy, self-fertile, productive and regular bearing tree. The variety has a large showy blossom and blooms during the early season, with a chilling requirement of about 500 hours. The fruit matures under the ecological conditions described in late May, with first picking on May 27, 2021. The fruit is uniform, fairly very large in size, acidic and sweet in flavor, very oblate in shape, clingstone in type, firm in texture, yellow in flesh color, full dark red with very minimal freckling in skin color, and has a bitter tasting kernel.

Description

Botanical classification: Prunus persica.

Variety denomination: ‘RED RAGE I’.

BACKGROUND OF THE VARIETY

In a continuing effort to improve the quality of shipping fruits, we, the inventors, typically hybridize a large number of peach, nectarine, plum, apricot, and cherry seedlings each year. We also grow a smaller 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 ‘Red Rage I’.

The present variety was hybridized by us in 2013 as a first generation cross using ‘Kay Diamond VII’ (U.S. Plant Pat. No. 18,715) nectarine as the selected seed parent and ‘18P1239’ (unpatented) nectarine as the selected pollen parent. Upon reaching maturity the fruit of this hybridization was gathered, and the seeds were removed, cracked, stratified, germinated, and grown as seedlings on their own root in our greenhouse facility. Upon reaching dormancy we transplanted them to a cultivated area of our experimental orchard located near Le Grand, Calif., in Merced County (San Joaquin Valley). During the fruit evaluation season of 2017 we 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, we 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 tree 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, ‘Kay Diamond VII’ (U.S. Plant Pat. No. 18,715) nectarine by being vigorous, by being self-fertile, by having a bitter kernel, by requiring about 500 chilling hours, and by producing nectarines that are mostly red in skin color, yellow in flesh color, that are clingstone in type, that are large in size, and that are acidic in flavor, but is quite distinguished from it by having globose leaf glands instead of being eglandular, and by producing nectarines that ripen about five days earlier, that are oblate instead of oblong in shape, and that are somewhat sweeter in flavor.

The present variety is similar to its pollen parent, ‘8P1239’ (unpatented) nectarine, by being self-fertile and by producing nectarines that ripen in late May and that are full red in skin color, oblate in shape, clingstone in type, and firm in texture, but is quite distinguished from it by producing fruit that is larger in size, that is acidic instead of sub-acidic in flavor, and that are yellow instead of white in flesh color.

The present variety is most similar to ‘Rose Bright’ (U.S. Plant Pat. No. 15,845) nectarine by having a vigorous tree, by having globose leaf glands, by having a large blossom, by being self-fertile, by having a bitter kernel, by having a similar chilling requirement, and by producing nectarines that mature in late May and that are mostly red in skin color, yellow in flesh color, clingstone in type, firm in texture, and acidic in flavor, but is distinguished therefrom by blooming a little earlier and by producing nectarines that are somewhat larger in size, that are more oblate and symmetrical in shape, that have less skin freckling, and that are much sweeter.

SUMMARY OF VARIETY

In summary, the present nectarine variety is characterized by a medium size, vigorous, hardy, self-fertile, productive and regular bearing tree. The variety has a large showy blossom and blooms during the early season, with a chilling requirement of about 500 hours. The fruit matures under the ecological conditions described in late May, with first picking on May 27, 2021. The fruit is uniform, fairly large in size, acidic and sweet in flavor, very oblate in shape, clingstone in type, firm in texture, yellow in flesh color, full dark red with very minimal freckling in skin color, and has a bitter tasting kernel.

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. 5, 2021, on the original tree during its eighth 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.
