USPP29127P2 - Nectarine tree named ‘red bright it’ - Google Patents

Abstract

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 variety blooms during the mid season and requires about 525 chilling hours. The fruit matures under the ecological conditions described in mid June, with first picking on Jun. 10, 2016. The fruit is large in size, globose to slightly oblong in shape, clingstone in type, firm in texture, yellow with red bleeding in flesh color, full red in skin color, and acidic in flavor.

Description

Botanical classification: Prunus persica.

Variety denomination: ‘Red Bright II’.

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 Bright II’.

The present variety was hybridized by us in 2008 as a first generation cross using a ‘5P452’ white flesh nectarine (unpatented) as the selected seed parent and ‘Kay Diamond VII’ (U.S. Plant Pat. No. 18,715) nectarine, as the selected pollen parent. Upon reaching maturity the fruit of this cross was gathered, and the seeds were removed, cracked, stratified, germinated, and grown as seedlings on their own root in our greenhouse. Upon reaching dormancy the seedlings were transplanted as a group 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 2012 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 reproductions 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, ‘5P452’ (unpatented) nectarine, by producing nectarines that are firm, mostly red in skin color, nearly globose in shape, and clingstone in type, but is quite distinguished therefrom by producing fruit that is yellow instead of white in flesh color and acidic instead of sub-acidic in flavor.

The present variety is similar to its pollen parent, ‘Kay Diamond VII’ (U.S. Plant Pat. No. 18,715) nectarine, by producing nectarines that are medium to large in size, firm in texture, mostly red in skin color, nearly globose in shape, clingstone in type, acidic in flavor, and yellow in flesh color, but is quite distinguished therefrom by having globose leaf glands instead of being eglandular, by blooming in the mid season instead of early, and by producing fruit that matures about twenty-five days later.

The present variety is most similar to ‘Spring Bright’ (U.S. Plant Pat. No. 7,507) nectarine by being self-fertile, by blooming in the mid season, by having globose leaf glands, and by producing nectarines that are firm in texture, mostly red in skin color, yellow in flesh color, nearly globose in shape, clingstone in type and very good in flavor, but is distinguished therefrom by producing fruit that is larger in size, that has more red bleeding in the flesh, that has a bitter instead of sweet kernel, and that matures about five days later.

SUMMARY OF VARIETY

In summary, the present nectarine variety is characterized by a large size, vigorous, hardy, self-fertile, productive and regular bearing tree. The variety blooms during the mid season and requires about 525 chilling hours. The fruit matures under the ecological conditions described in mid June, with first picking on Jun. 10, 2016. The fruit is large in size, globose to slightly oblong in shape, clingstone in type, firm in texture, yellow with red bleeding in flesh color, full red in skin color, and acidic in flavor.

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. 14, 2016 on the original tree during the 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.

It is to be noted that the 2016 fruit season in California was very warm during the spring and the ripening times of almost all varieties were about two weeks earlier than most other years.

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)

We claim:

1. A new and distinct variety of nectarine tree, substantially as illustrated and described, that is most similar to ‘Spring Bright’ (U.S. Plant Pat. No. 7,507) nectarine by being self-fertile, by blooming in the mid season, by having globose leaf glands, and by producing nectarines that are firm in texture, mostly red in skin color, yellow in flesh color, nearly globose in shape, clingstone in type and very good in flavor, but is distinguished therefrom by producing fruit that is larger in size, that has more red bleeding in the flesh, that has a bitter instead of sweet kernel, and that matures about five days later.
