Abstract

A new and distinct variety of ‘C. unshiu Marc. cv. Miyagawa-wase’, plant named ‘Jedae’, this new variety Citrus plant is an early-maturing satsuma mandarin reproduced and propagated asexually, and characterized by i) rough peel, ii) vertical corrugation from fruit stalk which results in uneven outer appearance of fruit, and iii) higher flavonoid content in the fruit, compared to ‘Miyagawa-wase’.

Description

The Latin name of the genus and species is: Citrus unshiu.
The variety denomination is: ‘Jedae’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of a mandarin tree named ‘Jedae’, which originated from ‘C. unshiu Marc. cv. Miyagawa-wase’ of early-maturing satsuma mandarin which is the most cultivated varieties in Jeju Island, Korea. ‘Jedae’ was obtained from ‘Miyagawa-wase’ by a radiation-induced mutation. The new mandarin variety is an early-maturing satsuma mandarin characterized by fruit shape and flavonoid components altered by artificial mutation breeding involving the gamma irradiation compared to ‘Miyagawa-wase’.
BRIEF SUMMARY OF THE INVENTION
The present invention related to a new and distinct variety of ‘Miyagawa-wase’, plant named ‘Jedae’. ‘Miyagawa-wase’ is the closest comparison to ‘Jedae’. The new variety Citrus plant is an early-maturing satsuma mandarin reproduced and propagated asexually by grafting in Seogwipo-si, Jeju Special Self-Governing Province, Korea from 2006 first and then further reproduced during 2006 to 2013, and characterized by i) rough peel, ii) vertical corrugation from fruit stalk which results in uneven outer appearance of fruit, and iii) higher flavonoid content in the fruit, compared to ‘Miyagawa-wase’.
In detail, the fruits of ‘Jedae’ were slightly larger than those of ‘Miyagawa-wase’. In addition, the fruits of ‘Jedae’ had the peels that were less smooth and more rugged on outer surface in terms of fruit shape, compared to fruits of ‘Miyagawa-wase’. The fruits of ‘Jedae’ had groove of radial shape from the fruit stalk and were found to have vertical corrugation in overall way when they were viewed from the side. Thus, the fruits of ‘Jedae’ were considered to have excellent fruit shape and have the potential to be developed into decorative Citrus fruits. The flavonoid, a functional substance contained in Citrus fruits, is typified by components such as hesperidin (HD) and narirutin (NRT). Such the flavonoid content was contained more in the fruit of ‘Jedae’ compared to ‘Miyagawa-wase’ cultivated under the same conditions.

The fruits of ‘Jedae’ exhibited characteristics almost similar to the fruits of ‘Miyagawa-wase’ in terms of sugar content and acidity. The fruits of ‘Jedae’ were slightly larger than those of ‘Miyagawa-wase’. In addition, the fruits of ‘Jedae’ had the peels that were less smooth and more rugged on outer surface in terms of fruit shape, compared to fruits of ‘Miyagawa-wase’.
The fruits of ‘Jedae’ had groove of radial shape from the fruit stalk and were found to have vertical corrugation in overall way when they were viewed from the side. Thus, the fruits of ‘Jedae’ were considered to have excellent fruit shape and have the potential to be developed into decorative Citrus fruits.
In addition, the fruits generated from ‘Jedae’ maintain their altered shapes described above from young fruit bearing stage to maturation stage in early December, and can be harvested with those of ‘Miyagawa-wase’ almost around the same time. However, the fruits of ‘Jedae’ showed distinctive difference from those of ‘Miyagawa-wase’ in terms of fruit shape arising from changes in peel traits.
FIG. 11 shows the photograph that compares the Citrus section of ‘Jedae’ (right side) with the fruit section of ‘Miyagawa-wase’ (left side). FIG. 12 shows the photograph comparing the white portion (albedo layer) inside the peel (‘Miyagawa-wase’ (left side) and ‘Jedae’ (right side)).
FIG. 11 and FIG. 12 also show that ‘Jedae’ is characterized by smooth fiber not protruding roughly regarding the surface that comes into contact with fruit flesh in albedo layer, unlike ‘Miyagawa-wase’. Therefore, the fruits of ‘Jedae’ showed good adhesion between fruit and fruit flesh and good storability, but could not be easily peeled.
As to the fruit color of ‘Jedae’, the fruit surface color is yellow orange (RHS orange 25A), fruit flesh color is light orange (RHS orange 26B), the fruit areola is absent, parthenocarpy is present, self-incompatibility is present, and seed is absent.
As to the productivity of the fruit of ‘Jedae’, the 7-year-old tree produces 11.4 kg to 26.5 kg per tree. The average weight per fruit is about 120 g.
