Description

New egg of Symbidium Agri plant {New variety of plant cymbidium Aguri}

The present invention relates to a new egg 'Cymbidium' new varieties 'Aguri' plants. More specifically, the present invention relates to a plant 'Aguri' belonging to a new breed of poultry symbidium, which is a peach-colored double ring, which is fixed as an excellent new breed for differentiation.

The origin of the symbidium called the egg eggs is a ring species native to the highlands (800-1,500m) of tropical Southeast Asia, such as northern India, Burma, Thailand and Vietnam. They are bred between the native species or by breeding these species with Japanese and Chinese species.

On the other hand, mass production of symbidium is possible by tissue culture techniques, in particular by the technology of nutrient system, that is, mericlone, which is obtained by extracting, culturing and growing apical meristem.

In particular, symbidium can be mass-produced by the mericlone technology, and it is easy to cultivate new varieties, and as a result, it can satisfy the demand of consumers by the low price. Accordingly, an object of the present invention is to provide a large amount of new varieties of symbidium which can be satisfied by the consumer at low cost.

The above object of the present invention is to select the existing egg symbidium as the parent and the bundling and hybridization and color (flower), leaf posture (plantation), flowering time (開花 期) aseptic seed species and other new varieties After cultivation by germination, the nutrients, especially spermatozoon, were extracted, tissue cultured, and subcultured.

1 is a photograph showing the phenotype of flowers, leaves, stems, etc. of plants belonging to a new breed of poultry symbidium of the present invention.

The present invention provides aseptic seed germination step of live seed; Corrective cutting step; Fertility culture step; It consists of three stages of passage of cultured Mericlone.

Hereinafter, the specific configuration and operation of the present invention will be described with reference to Examples, but the scope of the present invention is not limited only to these Examples.

Example 1

Germination and Growth of Aseptic Seeds Crossed with Lapine Joyner (♀) × Red Gloria (♂)

In order to germinate symbiotic seedlings, Knudson C medium was selected and germinated aseptically in fertilized medium with relatively lower concentration ratios of SO ₄ ^-2 , Ca ⁺² , NH ₄ ⁺¹ ions and instead of higher concentrations of K ⁺¹ ions. The embryos were grown in the usual manner and grown.

Seeds were selected to cross the Lapine Joyner line as the parent and the Red Gloria line as the parent.

Sterilization of the seedlings was performed by sterilizing for 20 minutes in a 10% Ca (CLO) 2 solution, and then put into sterile water to use the seed precipitated using a magnetic stirrer.

Example 2

Composition of the initial tissue culture badge

Unlike the seed culture medium of Example 1, in order to promote the initial growth of fertilization or fertilization of fertilization (莖 頂) was used as a medium composition as follows.

For fertility extraction medium, 8 g / L agar is added to the growth of PLB. pH was set at 5.5.

Example 3

Proliferation of Protoplasts (PLB)

The following KC medium was used for proliferation of protoplasts.

Example 4

Induction and rooting of new plant species of the present invention

As a medium for inducing and rooting new varieties of the present invention, Knudson (1946) medium below was used, and activated carbon was added to promote rooting rate and ground and underground growth.

The medium composition was prepared 100 times the liquid and stored in the refrigerator used, but Ca ^{+ 2} and SO ₄ ^-2 , Mg ⁺² and PO ₄ ^- form an insoluble precipitate was added when used.

On the other hand, when shoots were differentiated from protoplasts, they were transplanted into 300mL Flasks for seedlings, but seedlings were fixed for three generations by seedlings based on 20 weeks in 300mL flasks and 40 weeks in 500mL flasks. The horticultural characteristics of 'Aguri' plants are shown in the following table.

[Note] 1: flower stem inclination 1: upright 2: bent about 15 degrees 3: 30 degrees bend 2: disease resistance A: very resistant to root diseases B: strong C: moderate D: weak E: very weak Example 5

Purification of new varieties of plants

Seedlings that are about 15cm old after 3 months of passage are added to the flask and water is removed by tweezers. The medium is removed with distilled water.

Purified conditions were carefully placed in a basket with good air permeability and light permeability, and kept at 70 to 80% so that the moisture level was 5,000 to 10,000 lux, which is about 10% with nature.

The entire flowering state of the purified new varieties of 'Aguri' plants is shown in Fig. 1 and shows a peach-colored abdominal ring that is remarkably distinguished from the existing eggs.

As described above, the present invention as described through the embodiment, the present invention is a very useful invention in the plant new breed growth industry because it has the effect of providing a plant belonging to the new breed of Symbidium excellent egg for differentiation as a peach-colored biped.
