Description

{New Strawberry Variety Damhyang and the Method for Breeding the Same}

The present invention relates to a new variety of strawberry liquor and a breeding method thereof.

Strawberry ( Fragaria × ananassa Duch.) Is a perennial plant of Rosaceae and Strawberry. F. virginiana , native to eastern North America, and F. chiloensis , introduced in South America Chile, It is a species that has been made.

Globally, there are 17 species of wild species with 7 basic chromosomes (2n = 14), of which 9 are diploid, 3 are quadruple, 1 is hexadecimal and 4 is 8.

Strawberry is an important horticultural crop, which accounts for 10.6% of total domestic vegetable production (7,483 billion won) in Korea, reaching 799.7 billion won as of 2007. It is the next largest source of income for farm households (Ministry of Agriculture, Forestry and Fisheries, 2008).

Until 2005, most of the strawberry varieties grown in Korea were dominated by Japanese cultivars 'Akihime' and 'Red Pear', which account for more than 90% of the domestic strawberry cultivation area. However, , 'Mangyeong' and 'Gyungbang' were received by the growers. As of 2009, the cultivation rate of domestic varieties has a share of 56%.

However, the cultivated ratio of single varieties of citrus varieties is high in citrus varieties, and the dependency of red perl is high in irritable varieties.

In addition, Korea joined the UPOV (International Union for the Protection of New Varieties of Plants) in 2002, and the new crop protection target expanded to all plants including strawberries on January 7, 2012, It is expected that farmers will be burdened with paying royalties due to the protection of new varieties of plants by law.

Therefore, it is still necessary to develop domestic varieties.

The present invention has been completed under this background.

It is an object of the present invention to provide a new variety of berries.

Another object of the present invention is to provide a method of breeding the above-mentioned berries.

In one aspect, the present invention relates to a strawberry brand variety.

The new variety of strawberry of the present invention was obtained by crossing the Akihime (Chang Ji) varieties as a duplicate of the other varieties. The Akihime variety, which is a supermodel, is a single cone, , Seeds, or breeds that reproduce by seedlings.

In the above, the meaning of "conical cone" and "cone cone" are both the characteristics of strawberry in 2008 of National Seeds Institute of the Ministry of Food, Agriculture, Forestry and Fisheries in accordance with "Species Seeds (18) -165" In the fruit shape of 30 items, it means conical shape, and the conical shape means that the ratio of exaggeration to exaggeration is larger than the ratio of exaggeration to exaggeration of single cone, Means that the ratio of exaggeration is smaller than the ratio of exaggerated to exaggerated. Here, the exaggeration refers to the length of the largest fruit in the widest section of the fruit in the longitudinal direction, and the width refers to the length of the largest fruit in the widest section among the fruit sections in the width direction.

Means that the strawberry new variety variety of the present invention has a cone shape smaller than that of the native cultivar Akihime and the secondary cultivar, the ratio of the width to the length of the strawberry is 0.1 or more, preferably 0.2 or more, more preferably 0.3 or less. At this time, the fruit to be compared with each other is based on fruit at the same position in the same flower room. That is, it is calculated based on the number 2 of clean room (1 branch) for all varieties, or it is calculated based on number 1 of clean room for all varieties. Generally, the ratio of the number of malformations to the number of malfunctions is smaller than that of the number of malfunctions. It is preferable that the standard is used. As can be seen from the following Table 1, the ratio of the purified water 2 and the ratio of the standard and the width-to-height ratio of the present invention is 1.10, however, the Akihime variety of the present invention is 1.41, The varieties are smaller than the Akihime variety (0.31) and smaller than the varieties (0.3).

In the above, "seedlings" refers to a stem that is in contact with the ground as the stem extends, and is rooted and activated. In the strawberry cultivation farm, the silent breeding by the seedling is called the Runner breeding.

More specifically, the new variety of berries of the present invention is classified according to the type of the traits to be surveyed in the characteristic list of "Species Seeds (18) -165" for the characteristic examination of the new variety for the strawberry of 2008 by the National Seeds Institute of the Ministry of Agriculture, Forestry and Fisheries (Item 12 and item 25 in FIG. 2 of the accompanying drawings) and a similar qualitative item (item 9, item 14 in FIG. 2 to FIG. 6) , Item 15, item 27, item 30, item 32, item 43, item 44 and item 48), the following items (1) to (11) do.

< Example  1> New variety of strawberry Soothing  Fostering process

In order to cultivate new varieties of strawberry cultivated strawberry cultivar which is high in sugar content of fruit and resistant to pests and early production, it is recommended to use cultivated Akihime (Janghe) varieties with high growth and high yield among the cultivated cultivars and high sugar content and low acidity The varieties with high Tanganic acidity and high flavor were used as duplicates.

In 2006, it was artificially intercrossed. In the case of crossbreeding, the flower was bloomed before the blooming. After the operation was removed with tweezers, the pollen of the bloom was artificially pollinated to complete the water, and the bag was covered. It was sampled and shaded.

The cultivated seeds were germinated in commercial mixed forests in early May 2007, planted in a 32-well plug tray after germination, grown for 4 months, and cultivated in October 2007 to produce 250 excellent plants (F1VO generation, 06-06-01, 06-06-250) was preliminarily selected.

The average biomass of an individual, that is, the average mass of the entire plant (stem, root and leaf)) is determined based on visual observation, taste test, and measured value in 2008 among the 250 selected outlets in 2008 Four strains that are excellent and have excellent fruit quality (tannic acid ratio, tannic acid ratio is brix / acidity (%)) were selected (the top 10 lines were selected in order of superiority (V1 generation, 06-06-01, 06-06-02, 06-06-03, and 06-06-06), and 4th line among the 10 lines In the system, the overhang is the best (that is, the closest to the cone, more specifically, the left and right cuts generated when cutting the fruit in the longitudinal direction so that the widest cross- ) The final selection of one system with the highest Tangshan rain rate (V1 generation, 06-06-02) was given the name of "Damyang No. 1" system. After the preliminary test of the productivity test in 2009 (V2 generation, 06-06-02), the test of productivity test in 2010 (V3 generation, 06-06-02) V4 generation, 06-06-02) The final one line was selected and given the name of the breed as 'Kyeonghyang'.

In the preliminary test of the productivity test from 2009 to 2011, this test and the demonstration test were carried out to proliferate the third generation, and each generation and after the generation of the seedlings were observed (observed as hyperplasia), but after each generation and generation, And it was judged that the fixation was made in the V1 generation.

[Fig. 1] shows the cultivation status of the 'soya variety'. In FIG. 1, F1VO is a hybridization sequence after hybridization with seeds obtained after artificial hybridization, and V1 to V4 represent propagation periods from first generation to fourth generation by embryology.
