Description

A new variety plant of new kale, ROYALCHAE and method for breeding the same}

Figure 1 is a breeding schematic diagram showing the process from 1996 to 2007 to collect the kale "TV" and cauliflower "leaf group" to obtain a new plant "royal vegetable" of the present invention.

Figure 2 shows a view of the side and top view of the plant new varieties of the present invention "royal vegetable" grown in seedlings.

Figure 3 is a photograph showing the leaf shape of the new plant "royal vegetable" of the present invention.

The present invention relates to a new plant varieties royal vegetables and a breeding method thereof. More specifically, the present invention relates to a new plant royal species and a method for breeding the same, grown by self-modifying the species hybrid between kale and cauliflower.

Kale ( Brassica oleracea var. acephala) belongs to the Brassicaceae family, and the cabbage-derived leaves are sexually edible crops of various varieties. Scotch kale and Buddha kale are cold-tolerant of the growing vegetable crops. In plants, elongated leaves with long petioles form a solid rosette, with the edges of the leaves ranging from wavy to corrugated. It grows for a long time, and main stem reaches 60cm or more. In the United States, the entire rosette is usually harvested before the stems are elongated, but in the United Kingdom and Europe, the leaves are harvested sequentially from the bottom as the main stem is elongated. Kale is grown mainly for harvesting in autumn and winter because it is cold-resistant and can be harvested with fresh green vegetables when most fresh vegetables are no longer available. The leaves of fresh kale are not withered and dark blue green. It contains protein, vitamins A, B1, B2, and C. It also contains vitamins K and U and is edible for green juice, salad, and vegetables.

Kale has been rapidly growing due to the prominent shooting of Ssam vegetable since it was introduced in Korea about 15 years ago, and it is a vegetable that has grown rapidly to an indispensable position in Ssambap restaurant. Since Korea joined UPOV (International New Variety Protection Federation) in 2000, the number of crops to be protected is increased every year, and since 2006, additional kale items have emerged, resulting in the issue of loyalty. Therefore, there is a need to try to reduce foreign currency by developing new varieties that can replace domestically all kale varieties imported from the United States, Japan and the like.

Therefore, the present inventors have devised the present invention to solve the problem of existing kale that is poor in texture in the mouth when eating and eating raw wraps and cooked with salads, and to obtain a new kind of kale for reducing foreign currency.

Accordingly, it is an object of the present invention to provide a new breed of plants grown by raising a hybrid between kale and cauliflower.

Another object of the present invention is to provide a method for breeding the new plant.

The above object of the present invention is to obtain a seed parent by breeding the species hybrid by the bud breeding of kale and cauliflower and to select breeding individuals through the combination ability test, systematic purification, productivity test, characterization of new varieties and regional adaptation After the test, a part of the plant tissue was cultured to achieve the growth of plant objects having excellent traits such as iron and beta carotene.

Hereinafter, the configuration of the present invention will be described.

The present invention obtains a new kind of kale of the present invention in which the superior traits such as iron, beta carotene and the like have been introduced through a systemic purification by basing hybrids between cabbage and cabbage and calling it "royal vegetable"; Cultivating the royal vegetable of the present invention and then examining the properties; Comprising the step of propagating a plant object having excellent traits by tissue culture a part of the plant tissue of the present invention.

The present invention has the following characteristics, which are grown by harvesting kale "Tibish" and cauliflower "leaf" to obtain interspecific hybrids and child seed to obtain seed seed and systematically purify the deleted seeds. New varieties of royal vegetables ( Brassica), which are grown by asexual propagation by culture oleracea L. var. capitata ):

Leaf

Shape: slightly oval and round shape

Lobe: Hard, but soft, reddish, with very small scales of leaf blue, staggered in two or three positions not far apart.

Foliage: green on front and back

Leaf veins: reddish than flat

Limbus: red with some irregularities and bends

Foliar: Immaculate appearance as a thin layer of wax

2. Self-incompatibility: strong

3. Spring-type modified from green plant seed-spring type.

The royal chapel of the present invention is characterized by being grown through the following steps:

Kale "tibis" and cauliflower "leaf" to cross-border to obtain a hybrid species and to obtain a seed parent by the child,

Selecting and breeding the seed parent to obtain royal vegetables from the seed obtained by phylogeny to the F10 generation.

New varieties of plant royal vegetable of the present invention contains 70-80% of carrots with beta carotene, and compared with other cabbage products such as cabbage, cabbage, cabbage, lettuce, and kale. More than three times more, eight times more than lettuce, and much more, and calcium is similar to kale but more than seven times more than lettuce, and vitamin A retinol, which is good for women's skin care and disease, is three times more than kale. . In addition, thiamine (vitamin B), which is not found in conventional crops such as cabbage, cabbage, and kale, is characterized by the fact that it is contained in Ssamchuchu and royal vegetables. In addition, ascorbic acid (vitamin C), which is associated with anticancer effects, is similar to kale without significant difference, but contains 12 times more than lettuce.

Royal varieties of the present invention are sown and grown only one month to a half a month after planting so that when harvested and used as a ssam vegetable, because the growth rate is too large to use as a ssam vegetable, green juice can be used to make it suitable. In particular, the kale imported from the West is used a lot for green juice, but the taste is bitter and there is no objection to use it as a food and drink, but royal vegetables have a sweet taste and rich nutritional ingredients, so it is very suitable for use as green juice.

The new varieties of Royal vegetables of the present invention is suitable for hydroponic cultivation as well as soil cultivation and is very excellent for highland cultivation in summer. The cultivation method is not much different from the existing kale, but when grown too hot and humid, bacterial soft disease is likely to occur. It is very resistant to wart disease (root hog disease), which occurs in many cabbage crops.

The new varieties of the plant royal vegetable of the present invention is a ssam vegetable is very good to increase the immunity to children and the elderly to grow up because the soft and strong sweetness and iron, calcium, etc., compared to the conventional ssamka gives a bitter taste and stiff feeling.

Hereinafter, the present invention will be described in detail by way of examples, but the scope of the present invention is not limited only to these examples.

EXAMPLE

1996-1997: A new breed of breeding material, kale "TV" ( Brassica) olearacea L. var. capitata , 2n = 18, CC) and cauliflower "leaf" ( Brassica oleracea L.var. Species hybrids (F1) were induced between the acephala DCs and 2n = 18, CC).

1998-2007: The seed parent (F2) was obtained from the above, the individual was selected through the combination ability test, the characteristic test, the productivity test, and the adaptive test were carried out systematically until the F10 generation to produce a new hybrid "Royal vegetable". It was.

Example  2: cultivation of new plant of the present invention

The new variety plant "Royal vegetable" of the present invention obtained in Example 1 was cultivated according to a conventional method under similar conditions to existing kale varieties at the time of seedling. However, if the cultivation is too high and humid under the above conditions, it is easy to develop bacterial soft disease, so that the cultivation does not occur. Lime was always used as an airborne solution with borax, and when lime deficiency symptoms occurred, 0.3% of calcium chloride (60 g in 20 L of water) was sprayed three times at 5 day intervals.

Royal vegetables are available for hydroponic as well as soil cultivation. Cultivation conditions may be cultivated in a conventional manner.

One month to one and a half months after planting, the crops are grown only in the size of palms. At this time, the crops are used for ssam vegetable, and the leaves that are too large to be used for ssam vegetable are used for green juice.
