Mandarin plant named ‘Mikanken10’

Abstract

A new variety of Citrus sp. plant named ‘Mikanken10’ that has dense spines on the tree, leaf blade with emargination at tip, fruit with flattened general shape of distal part, and no navel opening.

Description

[0001] Common name: Mandarin.

[0002] Botanical classification: Citrus sp.

[0003] Variety denomination: ‘Mikanken10’.BACKGROUND OF THE NEW VARIETY

[0004] The present invention relates to a new and distinct variety of Mandarin, Citrus sp., which has been given the variety denomination ‘Mikanken10’.ORIGIN OF THE VARIETY

[0005] The parent varieties are ‘ARIAKE’ (male parent) (patented in the US as U.S. Plant Pat. No. 9,235) and ‘NANKO’ (female parent) (not patented in the U.S.), respectively.

[0006] The variety was developed and propagated in Uwajima, Ehime, Japan.

[0007] The variety was reproduced asexually by vegetative reproduction by top grafting one-year-old scions on rootstocks, in Uwajima, Ehime, Japan. The rootstock used was ‘MIYAGAWAWASE’ (not patented) as an interstock grafted onto Poncirus trifoliata (trifoliate orange).

[0008] In 1993, crossing the parent varieties and collecting seeds to be grown in the next year.

[0009] In 1994 and 1995, seeds were planted and grown.

[0010] In 1996, scions were grafted on top of root stock.

[0011] In 1998, the first fruit was harvested.

[0012] In 2003, lines were primarily selected.

[0013] In 2009, plants were secondary selected.

[0014] From 2010 to 2022 there were growing tests for their performance.

[0015] In 2023, breeding was completed with DUS status confirmed (distinct, uniform, and stable), whereby it was confirmed that the instant tree reproduces true to type in successive generations of asexual reproduction, and the variety was named ‘Mikanken10’.

[0016] Cultivation of variety does not require special conditions or treatments.

[0017] The variety is currently mainly intended for fruit production.SUMMARY OF THE VARIETY

[0018] This new mandarin plant ‘Mikanken10’ has dense spines on the tree, leaf blade with emargination at tip, fruit with flattened general shape of distal part, that distinguish it notably from its male parent ‘ARIAKE’, and no navel opening, that distinguish it notably from its female parent ‘NANKO’.

[0019] Also, ‘Mikanken10’ has no depression at the distal end of the fruit and no polyembryony of seeds, that distinguishes it notably from comparative variety ‘SEINANNOHIKARI’ (not patented in the U.S.).

[0020] In addition, the fruit of ‘Mikanken10’ has the following characteristics: The fruit size is approximately 200 g, the predominant color of the fruit surface is vivid orange, the rind thickness is thin, the strength of the segment walls is weak, the fruit has no seeds, in early December, the total soluble solids (Brix) of juice is about 15 degrees and the juice acidity is medium, and the time of maturity of the fruit is in early to mid-December.

[0021] Table 1 shows a comparison between the instant variety ‘Mikanken10’ and Male parent variety ‘ARIAKE’ and Female parent variety ‘NANKO’, as follows (average evaluation):

[0025] In the accompanying drawings, which are as nearly true as is reasonable possible to make in a color illustration of this type:

[0026] FIG. 1 is a color photograph showing a general view of an illustrative mandarin tree of the variety named ‘Mikanken10’ bearing fruits.

[0027] FIG. 2 is a color photograph showing flowers of ‘Mikanken10’.

[0028] FIG. 3 is a color photograph showing upper surfaces of leaves of ‘Mikanken10’.

[0029] FIG. 4 is a color photograph showing whole fruits (distal end, side view and stalk end), and transverse section and longitudinal section of fruits of ‘Mikanken10’.

[0030] FIG. 5 is a color photograph showing whole fruits (distal end, side view and stalk end), and transverse section and longitudinal section of fruits of ‘Mikanken10’ and ‘NANKO’, which is indicating difference of fruit: navel opening.

[0031] FIG. 6 is a color photograph showing whole fruits (distal end, side view and stalk end), and transverse section and longitudinal section of fruits of ‘Mikanken10’ and ‘ARIAKE’, which is indicating difference of general shape of distal part.

[0032] FIG. 7 is a color photograph showing upper surfaces of leaves of ‘Mikanken10’ and ‘SEINANNOHIKARI’, which is indicating difference of leaf: emargination at tip.

[0033] Due to chemical and / or digital development, processing and printing, the plants or portions of plants depicted in the photographs may or may not be precisely accurate when compared to the actual botanical specimens.DETAILED DESCRIPTION OF THE INVENTION
