Description

A Muehlenbeckia complexa new plant variety

The present invention relates to a new breed of murenbecia strains, and more particularly, to a new breed of murenbechia strains that are robust in nature and can increase ornamental value.

Muhlenbeckia complexa is an evergreen perennial herb that is native to New Zealand and Australia, and has about 250 species native to the tropics. It is an ornamental plant known as Trian in Korea. Murenvecchia has thin, delicate stems that grow long and long like hair, and fine leaves attached to the stems, making them more attractive than other vines.

These murenbechia is strong in the growth and adaptation to the room, so planted in a basket or high pots, and put the pots on the shelf and down the stems and grow, there is a sense of popularity, accordingly is very popular for ornamental. It is sold as an ornamental plant in the domestic market.

However, this murenbekia has a problem that because the color of the leaf is only green, it could not meet the consumer's desire for a variety of leaves.

The present invention was created in order to solve the above problems, and the object of the present invention is to provide a new breed of murenbechia mutant plants that can implement the color of the leaf in yellow and excellent growth.

In order to achieve the above object, the new varieties of murenbechia strains according to the present invention, as the cultivated by extracting azo-mutated stems from murenbechia, subcultured by more than six generations by cutting, (a) leaf color Is entirely yellow, (b) the leaf shape is generally round oval, (c) the leaf tip is blunt, (d) the leaf surface is glossy, (e) the leaf edge is smooth, and by asexual propagation Breeding, the breeding is implemented by performing the passages for eight generations.

According to the present invention, the leaf has a yellow color has an effect that can be implemented murenvecchia that can increase the ornamental value.

In addition, Figure 3 is a photograph showing the stem and leaves after the passage of the azomutated stem of Figure 1 once, Figure 4 is a stem and leaves after the passage of the azomutated stem of Figure 2 twice. 5 is a photograph showing the color of most of the leaves sprouting on the stem after the passage of the sub-mutated stem of FIG. 3 six times. And, Figure 6 is a picture for comparing the new type murenbechia strains of the present invention and the existing murenbechia, Figure 7 is a picture showing that a number of new varieties of murenbechia strains of the present invention are stored.

According to the present invention, after selecting azo-modified stems from muren-vecchia with green leaves, the varieties were fixed by using 8 times asexual reproduction of cuttings. The new varieties of muren-vecchia plants and their breeding method will be described in detail as follows.

1. The discovery of azo mutations

The present inventors have been working on flower propagation and breeding for two decades while working in flower business. Applicant. In the process of breeding a very popular murenvecchia for ornamental use among plants around January 2004, as shown in FIG. 1, the green and yellow partially mixed leaves and the whole yellow leaves were azo-mutated. The stem was excavated.

2. Variety fixation by cutting

The azomutated stem obtained by finding as described above was taken out, and cutting (8 passages) was performed by the method shown in FIG. 2 from eight times from mid-February 2004. For this purpose, the house was shaded, the temperature was maintained at 18-25 ° C. and the humidity 70-80%. In this state, the mutated stems were cut with a knife and inserted into peatmoss mixed soil.

One-time passage: The first cuttings were performed from February to March 2004. More yellow leaves were found on the stems of the muren-vecchia that were bred through the first cutting, as shown in FIG.

Two passages: In muren-vecchia, bred from the first cutting, the second cutting was carried out from June to July 2004 by cutting the stem with the most yellow leaves. In murenvecchia breeding through a second cutting, as shown in FIG. 4. More yellow leaves were found in the first cuttings than the Murrenbekia bred.

Three passages: In Murrenbecia, bred from the second cutting, the third cutting was carried out from September to October 2004 by cutting the stem with the largest yellow leaves. In murenvecchia, bred through the third cutting, more yellow leaves were found than the murenvecchia bred in the second cutting.

4,5,6 passages: Fourth, fifth, and sixth cuttings were performed from February to October 2005. As the passage was repeated, as shown in FIG. It became yellow.

7,8 pass-throughs: The seventh and cuttings were carried out from November 2005 to September 2006, and the green leaves were culled by cutting and inserting more open stems each time the yellow leaves were inserted than before. . And from the seventh cutting, it was difficult to find green leaves practically.

By inserting more than six passages and eight passages in the present example, it was possible to cultivate a new variety of muren-vecchia varieties that consist entirely of yellow leaves. These new varieties of murenbechia plants and conventional murenbechia are shown in Figure 6, the photo on the left is a new species of murenbechia strains of the present invention, the photo on the right is a general murenbechia.

The new varieties of murenbechia strains are vigorously multiplied through the asexual breeding method, and as shown in FIG. 7, many new varieties of murenbechia varieties are stored in the applicant's flower garden.
