Botanical classification: Prunus persica (L.) Batsch var. nucipersica (Suckow) C.K. Schneid.
Variety denomination: ‘SWEET REI’.
CROSS-REFERENCE TO RELATED APPLICATION This application claims priority to Japanese Plant Variety Registration Application No. 33273 filed on Jul. 23, 2018, which is incorporated by reference herein as if set forth in its entirety.
BACKGROUND OF THE VARIETY The present invention relates to a new and distinct variety of white nectarine tree (Prunus persica (L.) Batsch var. nucipersica (Suckow) C.K. Schneid.), which has been given the variety denomination ‘SWEET REI’. This novel variety was found by natural hybridization of the seed parent variety ‘SWEET VENUS’ (Japanese Plant Variety Registration No. 12301, registered on Nov. 8, 2004), in Tsukidate-cho, Date-city, Fukushima-prefecture, Japan.
This new white nectarine produces fruits, which are late-maturing, having high brix and relatively low acidity white flesh as well as attractive dark-red skin color, excellent eating quality, and are easy to eat because of its freestone flesh.
ORIGIN OF THE VARIETY As stated above, the new variety of white nectarine ‘SWEET REI’ was obtained from natural hybridization of ‘SWEET VENUS’ (Japanese Plant Variety Registration No. 12301, registered on Nov. 8, 2004), the seed parent of the present variety, in Tsukidate-cho, Date-city, Fukushima-prefecture, Japan, where it was tested.
In 2011, ‘SWEET VENUS’ was open-pollinated in the inventor's orchard in Tsukidate-cho, Date-city, Fukushima-prefecture, Japan, and 10 of its natural hybrid seeds were seeded and the resultant seedlings were grown at the orchard.
Five (5) germinated seedlings of the above-obtained seedlings were further grown, and the first fruits were observed in 2013. Among the 5 trees from the germinated seedlings, the inventor selected one tree as a mother tree because of its characteristics as having high brix (sweet) and relatively low acidity, excellent eating quality, and easy to eat fruits. In 2014, the second generation of the mother tree was grown by asexual reproduction by grafting onto a wild white-flowered peach tree rootstock (non-patented, being indigenous on a mountain in Tsukidate-cho, Date-city, Fukushima-prefecture, Japan), and the observation of the characteristics of the second generation tree was started. The asexually propagated tree remained true to the original tree (i.e., mother tree), and all characteristics of the tree and fruits of the mother tree were transmitted. In 2017, this new variety was denominated by the inventor as ‘SWEET REI’.
The above-identified mother tree and the second generation tree of ‘SWEET REI’ have been maintained in Tsukidate-cho, Date-city, Fukushima-prefecture, Japan.
SUMMARY OF THE VARIETY The new white nectarine variety ‘SWEET REI’ exhibits outstanding and distinguishing characteristics when grown under normal nectarine cultivation practices, including:
-
- (1) high brix (Brix 15 to 17 degree), relatively low acidity, and white flesh fruit;
- (2) excellent eating quality fruit;
- (3) being easy to eat because of its freestone fruit;
- (4) attractive dark-red fruit skin color; and
- (5) no deterioration of eating quality of fruit even after storage for two weeks in a refrigerator.
The fruits of ‘SWEET REI’ is suitable for fruit gifts, such as fruit gift boxes or fruit baskets, since it has attractive dark-red skin color as well as excellent eating quality, and is easy to eat because of its freestone flesh.
In addition, since the fruit of ‘SWEET REI’ has high brix and relatively low acidity, it can also be used for preparation of processed fruits, such as fruit cake, fruit jelly, canned fruits, fruit juice and fruit jam.
For reliable description, the characteristics of ‘SWEET REI’ are described as compared to those of the yellow nectarine variety ‘SWEET VENUS’ (the seed parent of the present variety, Prunus persica (L.) Batsch var. nucipersica (Suckow) C.K. Schneid.) and the representative variety of white peach, ‘Kawanakajima Hakuto’ (Prunus persica (L.) Batsch), its the attached Table 1 (Table of Characteristics).
As stated herein below and described in the attached Table of Characteristics, ‘SWEET REI’ has apparently different characteristics from those of the variety ‘SWEET VENUS’ and the variety ‘Kawanakajima Hakuto’.
‘SWEET REI’ clearly differs from its seed parent variety ‘SWEET VENUS’, which has yellow, relatively firm and clingstone fruits, in that ‘SWEET REI’ has dark-red fruit skin color, white fruit flesh, and relatively soft, freestone and easy to eat fruit. Moreover, since ‘SWEET REI’ needs not being grown under plastic cover, its cultivation is easier than that of ‘SWEET VENUS’, which needs to be plastic covered.
In addition, ‘SWEET REI’ clearly differs from the representative variety of white peach ‘Kawanakajima Hakuto’, which has Brix 13 degree, in that ‘SWEET REI’ has higher Brix (Brix 15 to 17 degree).
‘SWEET REI’ is in fact outstanding and readily identified as being such.
It should be noted that the plant age of all the plants of ‘SWEET REI’, which were observed and photographed for botanical description, was 3 years (except for the 7-year-old mother tree of ‘SWEET REI’ in FIG. 21).
DESCRIPTION OF THE DRAWINGS This new white nectarine variety is illustrated by the accompanying digital color photographs, depicting defining characteristics of the plant by the best possible color photography. Colors of foliage, flowers, fruits and other plant parts may vary from year to year depending on, among other factors, nectarine cultivation practices, light conditions, air temperature, soil fertility, etc.
