Description

Symbidium new breed Foolish-GF1 and its breeding method {NEW VARIETY PLANT OF NEW CYMBIDIUM, BABOCY-GF1 AND METHOD FOR BREEDING THE SAME}

The present invention relates to the mysterious new varieties Fuchsia-GF1 plants, and especially to bloom twice a year, good income, good color and fragrance, good commodity, easy to cultivate, easy to cultivate, cultivation of new symbiotic species- GF1 relates to a plant.

About 70 species of Cymbidium grow in tropical Asia, from the Himalayas in the north to Japan in the east and northern Australia in the south.

It has long been recognized as an eruption in Korea, China, and Japan, and it is known as one of the four soldiers by the literary people. The temperate symbidium native to East Asia is called Dongyang Ran, and the tropical or subtropical symbidium is called Western Ran.

On the other hand, the mass production of symbidium is possible by tissue culture techniques, in particular, by the nutrient system, that is, mercury technology, which is obtained by extracting, culturing and propagating growth points or parietal fission tissues. .

Therefore, symbidium can be mass-produced by the mercury technology, and breeding of new varieties is easy, and as a result, it can satisfy consumer demand with low price.

In addition, the symbidium varieties produced and sold in the past are 'Oriental', 'Big Country', 'Hanran', 'Chunran', 'Daemyung Bonded', 'Steel timber timber', 'Geumhwasan', 'Sun dust', 'Miss Taipai' 'There is.

The symbidium varieties are difficult to sell because of the low ornamental value without flowers and leaves and flowers that are not upright because there is a hassle to stand a flower stand when growing a flowering liquor.

In addition, the varieties (FIGS. 1a and 1b) mostly imported from China, Japan, Taiwan, etc. are low in domestic adaptability, their growth rate is low, and it is difficult to see the flowers because they are not easy to cultivate and bloom only in winter to spring even if the flowers bloom. Therefore, when flooding, there is a problem that the price is lowered.

An object of the present invention is to provide a symsidium-GF1 plant of Symbidium new varieties, which have good income, good color and fragrance, good commerciality, and easy cultivation.

Symbidium ( Cymbidium ) new breed "Babocy-GF1" of the present invention for achieving the above object is Cymbidium 'Sun dust' and the Cymbidium 'steel bones' of the bone (♂) Obtained by hybridization between species, the color of the leaves is green, the gloss of the leaves is normal, the shape of the leaves is upright, the length of the leaves is about 40cm, the leaf width is about 1.2cm, the number of leaves is 3-4, The color of flowers is yellow and floral scent, and the flowering period is March ~ May and September ~ October, twice a year.

The new Cymbidium varieties are used for ornamental or differentiation.

Cymbidium new breed "Babocy-GF1" breeding method of the present invention through the hybridization between the species (ym) Cymbidium 'Sun dust' and the copy (♂) Cymbidium 'steel timber timber' After culturing the formed hybrid seed in the culture medium, the protocorm like body is selected and propagated, and then seedling (Shoot) differentiated from the prokaryote is seeded and breeding.

According to the present invention, since the super-type is an upright type, intensive cultivation per unit area is possible, and since the flower stand is an upright type, there is no need to stand the prop of the flower stand, thereby providing a new symbidium species that are easy to grow and manage.

In addition, it can bloom twice a year, increasing income. It has a scent, and the new color of Symvidium, which is bright and vivid with yellow color, has high ornamental value and is also valuable as a commercial value.

When shoots are differentiated from the protoplasts (PLB), they are transplanted into 300mL flasks for seedlings, but seedlings are based on 20 weeks in 300mL flasks and 40 weeks in 500mL flasks. The average height of more than 90% of the leaves was measured, the lateral width was the length of the middle leaf width, and the number of leaves was the number of leaves except the lower leaves.

As a result, new symbidium varieties (FIG. 2c) exhibiting the horticultural characteristics as shown in Table 5 was bred, and in the present invention it was named symbidium ( Cymbidium ) new breed "Babocy-GF1 (Babocy-GF1)".

division New breed of the present invention Cymbidium 'Babocy-GF1' Lobed Green (Figure 3c) Leaf length 40 cm Leaf width 1.2 cm Form (super fine) of plant leaf Upright Number of leaves 3-4 Color Yellow (Figure 4c) Flowering time March-May, September-October Blooming 2 times / year virus none Production method Tissue culture

Example 4 Pure Greenhouse Cultivation

Seedlings seeded in Example 3 about 15cm seedlings are planted in the conception to purify the seedlings, after 4 months of transplantation, transplanted into 6cm pots mixed with ovarian and bark 6: 4, and transplanted into 12cm pots after 8 months Cultivation was carried out.

In the cultivation management, the temperature in the greenhouse was 22 ℃ ± 2 ℃, humidity 60 ~ 80%, and brightness was 4,000 ~ 5,000Lux.

As a result of the cultivation, as shown in Figure 2c leaves and flowers stand upright intensive cultivation per unit area is possible, cultivation effort is reduced by not having to stand the stalk of the flower stand, it is easy to breed and can be used for differentiation.

In addition, it blooms twice a year to contribute to income increase, has a fragrance, as shown in FIG.
