Description

New Cultivar of Hosta minor Yellow Dream}

The present invention is a zombie ivy ( Hosta minor ) of the new species “Yellow Dream”. More specifically, the seeds obtained by self-modifying the zombie ivy were treated with mutagen, and then grown, resulting in a high ornamental value zombies ( Hosta). minor ) 's new breed "Yellow Rim".

Beetle plants are widely used as garden plants, and their demand is increasing day by day as the world's four largest flower beds. The Zombie Beetle ( Hosta minor ) is a perennial herbaceous plant that grows in the forests of Mt. Moak and Jeju Island in the Gimje city of Haenam, Jeollanam-do, and Jeonbuk.

Looking at the appearance of the zombie beetle, the stem stands upright, about 30cm long, and the stem is short and shows the shape of the string-shaped beard roots. The leaves come out in a pile, stand at an angle, wide egg-shaped, about 10cm long. Under leaf has a shape flowing from petiole to shallow petiole, flowers bloom in July-August and light purple (Fig. 1).

The stalk of zombies is about 30cm long, with vertical lines, and the flowers are biased to one side and run in the form of gunshots. Bracts are bassos, corollas are bell-shaped, about 5cm long, with six ends, flipped over. Six stamens and one pistil are long facing out and the fruit is fruited in September.

Recently, the demand for various kinds of ornamental plants is increasing, which can be planted for differentiation or gardening, especially afterglow and shade, and there is a growing demand for the development of new varieties of native cold beetroot plants with high cold resistance.

Accordingly, the present inventors earnestly endeavored to develop an ornamental plant having a beautiful leaf color. As a result, the zombie herb as a promising flower resource native to Jeju Island was collected and subjected to self-hybridization. Thus, yellow-green individuals having no spots or patterns on the entire leaves were selected to complete the present invention.

An object of the present invention is zombie ivy ( Hosta minor ) 's new breed "Yellow Dream".

In order to achieve the above object, the present invention is obtained by mutating a zombie ivy ( Hosta minor ) seeds, zombie ivy having the following characteristics ( Hosta) minor ) offers a new breed of "Yellow Dream":

(a) leaf color is pure yellow green without spots or patterns, leaf shape is lanceolate;

(b) leaf width 1.8-2.3 cm, leaf length 3.8-4.5 cm, leaf length 2.0-2.3 cm, height 3.5-4.6 cm, 12-15 leaves per aeration;

(c) the flowers are purple flowers;

(d) 35-40 cm flower garden, 13-18 flower plants per flowerbed, 13-18 cm flower length, 6-July flowering; And

(e) Fire hydrant 2.3-2.8cm long, 1.2-1.5cm wide.

New varieties of zombie beet according to the present invention "Yellow Rim" is a plant that grows after self-modifying the zombie beet, which is a plant native to the valley and forests of the mountain between 300-600 m above the southern slope of Hallasan, Jeju Island It is a new kind of industrially useful product that has high ornamental value and is expected to be competitive both domestically and internationally.

The present invention is a zombie ivy ( Hosta The seeds obtained by self-correcting minor ) were treated with mutant MMS (methyle methane sulfonate) and then grown to a new breed of “Yellow Dream” of Zombie ivy ( Hosta minor ).

In the present invention, in order to develop a new kind of "Yellow Rim" of zombie ivy, the seeds obtained by hybridizing zombie ivy at the time of flowering in June-July were obtained, and then used as a mutagenic chemical MMS (methyl methane sulfonate) After the treatment), new varieties were cultivated by selecting the leaves with patterns on the leaves.

In the present invention, the mutagens are MMS (methyl methane sulfonate), γ-rays, X-rays, ultraviolet rays, EMS (ethyl methane sulfonate), NaN ₃ (sodium azide), NMU (N-nitroso-N-methylurea) , Colchicine, an alkylating agent, an aromatic amine, a nitro compound, and at least one selected from the group consisting of peroxides, and preferably MMS (methyl methane sulfonate).

Yellow Dream according to the present invention has the following characteristics:

(a) leaf color is pure yellow green without spots or patterns, leaf shape is lanceolate;

(b) leaf width 1.8-2.3 cm, leaf length 3.8-4.5 cm, leaf length 2.0-2.3 cm, height 3.5-4.6 cm, 12-15 leaves per aeration;

(c) the flowers are purple flowers;

(d) 35-40 cm flower garden, 13-18 flower plants per flowerbed, 13-18 cm flower length, 6-July flowering; And

(e) Fire hydrant 2.3-2.8cm long, 1.2-1.5cm wide.

In the present invention, the lanceolate is one of the words indicating the shape of a leaf, a flower, or a petal, and is a term that refers to a shape that is thin and long, the tip is pointed, and the bottom is slightly convex from the middle.

Yellow Dream is 13 ~ 18 irises per flower and 13 ~ 18cm in flower length. It is light purple with many flowers running to one side. Po is not uniform in size, runs on each flower and has a distinct vein like leaf. There are 6 stamens in flower and 1 pistil. Fruits are capsules, long lanceolate, bursting from their backs, pouring black seeds with wings.

In general, since the zombie beet can be repeatedly reproduced by nutrient breeding, tissue culture, etc. well known in the art, it is obvious to those skilled in the art that the yeast rim according to the present invention can also be repeatedly repeatedly reproduced like the zombie beet. It will be called.

The new varieties "Yellow Rim" of the present invention, while the leaf color of the existing zombie ivy is dark green single color, the entire color of the leaf is bright yellow-green, so it is very excellent as an ornamental plant, such as for eruption and flower bed. In addition, the new breed "Yellow Rim" of the zombie ivy is cultivated by applying a combination of mutant breeding and selection breeding methods, it will be excellent in the domestic and foreign markets, and excellent in traits and excellent commercial properties.

Hereinafter, the present invention will be described in more detail with reference to Examples. These examples are only for illustrating the present invention, and it will be apparent to those skilled in the art that the scope of the present invention is not to be construed as being limited by these examples.

Example  1: Training course

At the end of June, the flowers of the zombie ivy were hybridized with their flowers to collect mature seeds in early October and then stored in a refrigerator at 10 ° C.

Example  2: mutant somatic cell development

The following year, in March, seeds (about 15,000) were taken out of the refrigerator, soaked in hot water at 23 ° C. for 24 hours, and then taken out, wrapped in wet gauze, and stored in a constant temperature at 24 ° C. for 3 days. In order to induce mutations, the seeds were immersed in a solution of methyl methane sulfonate (MMS), a mutant organic chemical, for 24 hours, and then taken out and washed. The washed 1,500 seeds were sown in a seeding box, but the cultured soil was formed so that the ratio of subleaf soil: pitmos: masato was 1: 1: 1, and the management temperature for germination was maintained at 23 ° C ± 2 ° C.

Example  3: Somatic Mutant Plant Selection

Seeds began to germinate (about 11,000) 10 days after sowing, and after 3 months, the patterned individuals (about 45) were reselected among the individuals (about 1,000) that had mutated leaves (Figure 2). . Among them, the yellow-green pattern appeared and was grown for 4 years, and after the growth characteristic investigation, it was confirmed that the characteristics of the varieties were expressed uniformly.

The new varieties of zombie ivy fostered by Examples 1, 2 and 3 have the characteristics of leaves and flowers as shown in Tables 1 and 2, and named them “Yellow Dream” (FIG. 3 and 4).
