Description

The present invention relates to a cauliflower cultivar having a long flower stem (flower infarct) and a light green outer leaf and growing in a standing manner.

A group of genetically similar specific traits among the same type of crop is called a variety. That is, even if it is the same kind of agricultural product, the difficulty of cultivation, resistance to pest damage, yield, quality (food texture / taste), and the like differ depending on the variety. For this reason, in crops, especially main crops such as rice and wheat, cultivar improvement has been performed for a long time to obtain better varieties.

One such crop is cauliflower (Brassica oleracea var. Botrytis), a vegetable improved from a variety of cabbage, and is known as a vegetable rich in nutrients such as vitamins and minerals.

In particular, a collection of white buds formed on the heads of stems (flower buds, hereinafter referred to as “cauliflower”) is used as an ingredient in various dishes. Conventionally, varieties have been improved so that flower buds suitable for each dish can be produced, and various varieties have been bred (see Non-Patent Document 1).

However, cooking variations and taste preferences of people have changed with the times, and cauliflower having more diverse characteristics is required. In particular, in recent years, an increasing number of consumers prefer cauliflowers that are soft and sweet and have no taste, but there is a problem that none of them meets the needs of such consumers.

At the same time, cauliflower producers wanted to produce cauliflower having the above characteristics and a large yield, but there was a problem that no cauliflower varieties having such characteristics existed. there were.

The inventor of the present invention has succeeded in cultivating the following epoch-making cauliflower varieties as a result of continually improving varieties regarding the above-mentioned problems.

The first aspect of the present invention for solving the above problems is that when cultivated under the same conditions as a conventional cauliflower variety, the flower stem is 1. The cauliflower varieties are characterized by being longer than twice.

Here, “conventional cauliflower varieties” include all known cauliflower varieties, and examples include cauliflower varieties “Snow Crown” (registered trademark). “Flower stem” means from the root of the flower stem to the tip of the flower stem.

In the first aspect, the flower stem is 1.2 times longer than the plant body of the conventional cauliflower cultivar, so that the flower bud (cauliflower) is larger than that of the conventional cauliflower cultivar (for example, 1500 g or more). As a result, compared to conventional cauliflower varieties, the yield of cauliflower can be significantly increased for the same cultivation area. Here, the “plant body” may be either a plant body (individual) or a part of the plant body.

A second aspect of the present invention is the cauliflower variety according to the first aspect, wherein the cauliflower variety is a cauliflower variety specified by FERM BP-22331.

In the second aspect, a cauliflower that is soft and sweet and has no peculiar taste can be obtained. In addition, the plant of this cauliflower cultivar has an appearance that the outer leaves are light green, slightly larger and more upright, and heat resistant than the plant of the conventional cauliflower cultivar cultivated under the same conditions. It has the characteristics of strong disease resistance and easy cultivation.

According to a third aspect of the present invention, there is provided an individual of the cauliflower varieties described in the first aspect, a progeny individual of the cauliflower varieties described in the first aspect, an individual of the cauliflower varieties described in the second aspect, and a second In the alternative individuals obtained by mating two individuals selected from the group consisting of the progeny individuals of the cauliflower varieties described in the embodiment. Here, the mating method is not particularly limited.

In the third aspect, cauliflower varieties having the same characteristics as the cauliflower varieties according to the first aspect and the cauliflower varieties according to the second aspect can be obtained.

A fourth aspect of the present invention resides in the seed of the cauliflower variety described in any one of the first to third aspects.

In this 4th aspect, the plant body of the cauliflower variety of the 1st-3rd aspect and its cauliflower can be obtained easily using the seed.

FIG. 1 is an appearance photograph of the flower varieties according to the first embodiment. FIG. 2 is a photograph of the flower stem of this variety according to Example 1.

(Cauliflower variety according to the present invention)
As described above, the plant body of the cauliflower cultivar according to the present invention has a flower stalk that is 1.2 times longer than that of the conventional cauliflower cultivar. It has the characteristic of becoming.

In addition, the cauliflower varieties in the present invention are not limited as long as the plant body has the above-mentioned characteristics, but since it is larger than the cauliflower of the conventional cauliflower varieties and can harvest sweet cauliflower, Edible ones are preferred.

Furthermore, in this invention, the cultivation conditions for comparing with the conventional cauliflower varieties are not specifically limited, What is necessary is just the same cultivation conditions. As a cultivation condition, a common cauliflower variety cultivation method can be used.

In the present invention, the length of the flower stem is compared with the cauliflower varieties according to the present invention after the flower buds are formed, about 10 days have passed, and the flower stems have grown and the flower buds appear to have loosened. At the time of.

In addition, unlike the conventional cauliflower varieties, the cauliflower varieties according to the present invention appear to be in a state where the flower stems grow and the florets appear to loosen after about 10 days have passed since the florets are formed. The length of the flower stalk in that state is 1.2 times or more, preferably 2.0 times or more longer than that of a conventional cauliflower variety cultivated under the same conditions. At that time, the length of the flower stem is compared. As a specific example, for example, the lengths of flower stems are compared within 3 days before and after 75 days after the first day of sowing.

Examples of the cauliflower varieties of the present invention include the cauliflower varieties deposited under the accession number: FERM BP-22331 or their progeny lines. The deposit information is shown below.
