The present invention relates to a new varieties of citrus varieties, and more specifically, in the tangerine mandarin jujube system, red azo, high sugar content, and fast production of azo variants are captured, and the primary tangya jukju, and then tangyeun It is related to the new varieties of citrus varieties that are grown through the process of gluing and immersing them, and the same in the high-receiving and sapling-growing water, which are equally reduced in production, high in sugar content, and which have a reddish dark color.

The plant, commonly called Citrus spp , is a plant belonging to the genus Citrus, Gold Persimmon, and Tangerine. These third genus plants are distributed on several islands in the southeastern part of the Asian continent. However, no citrus plants exist in the Austrian continent, but only the genus Microcitrus and Elemocitrus belong to the third genus belonging to the same citrus family. This genus is very different from citrus 3 genus in form, but has high hybrid affinity, and many hybrids are produced. Thus, despite the ancestral kinship between the citrus fruits of Southeast Asia and the two genus of Austria, they show a great difference in form because they have walked the path of independent evolution in other regions.

Currently, the status of citrus fruits is a vitamin source (vitamin C 31-40mg / juice 100cc, vitamin A 11-50I.U / juice 100cc), dietary fiber source (cellulose, pectin, etc.), organic acid source ( Citric acid, malic acid, etc.) and free sugars (glucose, fructose, etc.).

Many studies have been conducted to utilize functional substances contained in Jeju citrus fruits, anticancer substances using essential oils (terepine, R-limonene) contained in citrus peels, natural detergents and flavor extracts, and flavonoids containing citrus fruits (hesperidin, na Lysine, nobiliretin, etc.) as a capillary potentiator and cancer suppressor, limonoids (liminine, aniline, nomiline, icachin, etc.) contained in citrus juice, as a tumor suppressor component, carotenoid (β- Adult disease prevention using carotene, cryptotoxanthin, and the like, that is, an effect of inhibiting aging by inhibiting free radicals in the body and inhibiting cancer, and the like.

Citrus cultivation on Jeju Island is considered to have been made much earlier than this, based on the record of Goryeogi that tribute the citrus fruits in 476 AD and King Munju's second year. Most of the cultivars at this time were native to Jeju, and 22 varieties were grown including kumquat, wild mandarin, blue mandarin, tangerine, citron, yugam, sugar citrus, red mandarin orange, potato, kumquat, kumquat, soybean persimmon and persimmon. It has no taste and is poor in quality, and has been gradually improved to a new variety, and now only a few varieties can be found, such as bottle orange, sugar citron, citron, blue mandarin orange, jeongjeong tangerine, red tangerine and tangerine.

Citrus fruits, like other fruit trees, have a long breeding period, and multiplicity makes citrus varieties difficult. When the seed is matured when the cultivars are mated, the zygotic embryo is pressed by a nuclear embryo and the germination is low, which makes it difficult to achieve the desired target of the breeding breed.

For the development of citrus varieties, methods such as breeding by the main jury, breeding by hybridization and breeding by mutation are mainly used. Citrus seeds are single and multiply depending on the type. In the varieties that make the main jury, the seeds are called multiply seeds by combining several main jujubes, like the original fertilized oily pear. These varieties are called multiply varieties and belong to them such as Wenzhou citrus, mandarin orange, citron, cinnamon, Lee Ye-gam, and tanza. When the seeds are plentiful, one of them is fertilized sexual embryo, and the other is undeveloped and developed embryonically after fertilization from the pericardium of the pericardium around the backpack. This is called nucellar or apogamic embryo. Call. A fertilized embryo formed from this is called a gametic embryo.

As Korea's citrus industry faces many difficulties due to the opening of imports, it is most important to produce fruit with international competitiveness, thereby promoting demand expansion internally and expanding exports externally. Unlike main grains, fruit trees have been engaged in fierce competition between mountain regions under the principle of market economy from the early stage of industrial development. At the consumption stage, the superiority and high competitiveness of production fruits can be thought of only in terms of quality, and the superiority of the production region is recognized as the result of the production of high quality fruits.

The first condition of the fruit quality determination is the variety, and the development of a new citrus variety with excellent characteristics in line with the diversifying market demand is the most urgent task to be solved in the citrus industry.

Accordingly, the present inventors have made diligent research efforts to cultivate citrus plants having excellent properties such as good coloration, high sugar content, fast acidation, and low sour taste. The present invention was completed through a process of picking up and sticking to the crude wenju tree, and then pinching and immersing it in the tanza tree.

The present invention has been made in accordance with the above requirements, the object of the present invention is grown through asexual proliferation process, such as folds, using azo variants having a deep red color, high sugar content and fast subtractive characteristics, high incidence and seedlings It is to provide a new varieties of citrus varieties that have the same excellent characteristics in the growing water is stably maintained by asexual breeding.

In order to achieve the above object, the present invention captures an azo variant having a deep red color, high sugar content, and quick production in a citrus citrus persimmon strain, and first attaches it to a crude poncho plant, and then folds and folds it into a tanza plant. It is related to new varieties of citrus plants that can be grown through high process and sapling growing water in the same way, and have high sugar content, reddish red color, and stable mass production by asexual breeding.

Fruit of the citrus strains of the present invention is dark red of the skin and the flesh, the fruit is characterized in that the spherical to spherical shape.

In addition, the fruit of the citrus varieties of the present invention is characterized by a high sweetness of 11 ~ 12 ° Brix, the acidity of the maturation period, the acidity is less than 0.9% so that the acidity is less.

Hereinafter, the present invention will be described in more detail.

One. Azo Operation

In the late 1980s, the Citrus Agricultural Co., Ltd., located in Wimi-ri, Namwon-eup, Jeju-si, selected azo variants with different characteristics from the parameters such as dark red, high sugar content, and fast production in the Namgamjuju system that artificially bonded Namgamjuju to the Tangza plant. By comparing the parameters with the characteristics for two to three years, the azo variant was maintained.

2. Azo  Passage breeding and breeding

In 1996, the azo mutants obtained from the above selection were taken out and first adhered to the crude hot-spring plants planted in the same parameter source, and the fruits were grown by selecting the fruit color, sugar content and acidity as assay characteristics. Acceptance is easy to glide, the eye height is good after glide, graft operation is easy, but spring branches can be used every year from three years old, spring or summer is preferred. The collection of receptionist is collected at pruning time between February and March, and the leaves of leaves are prepared 2-3mm. Storage of the reception is completely moistened with 5 ~ 6 layers of newspaper paper, and then wiped off the water. Then, the receptionist is wrapped and wrapped in vinyl and placed in a refrigerator at 5 ~ 7 ℃ until the beginning of May. On the other hand, when stored in the state of moisture in the reception, the mold is easy to rot and decay, so it is opened during storage and cut once to prevent the mold from writing at the reception cut so that the conduit is not blocked. The splicing was carried out around April 30, and the specific method was performed by a conventional method well known to those skilled in the art, and a description thereof will be omitted.

In 1997, seedlings grown and grown through the first juncture were taken out in the same manner as above. As a result of the characterization test through the fixation process, it was confirmed that the characteristics of the fixation system were consistently consistent with those of the azo variant parameters, and that the properties such as coloration, sugar content, and acidity were maintained better than those of the normal crude citrus fruits 1 to 6). Through the above process, the propagation-fixed strain 'affection' ( Citrus spp ).

On the other hand, the cropping method and cultivation management in the 1 and 2 process was carried out in accordance with the Rural Development Administration standard agricultural textbook (citrus cultivation).
