Description

종자생산성이 안정화된 고임성 배무채 신품종 식물{A New plant variety of baemoochae xBrassicoraphanus having a stabilized high fertility} A new plant variety of baemoochae xBrassicoraphanus having a stabilized high fertility

본 발명은 배무채 식물의 종자생산성이 안정화된 고임성 배무채 신품종 비비(BB) 식물에 관한 것이다.The present invention relates to a new type of BB plant, which is stabilized in seed productivity of the BB plant.

본 발명자는 배추와 무 간의 속간잡종식물인 "배무채(속명: xBrassicoraphanus, genome : aarr, 2n=38)"를 육성하고 이를 특허 취득한 바 있다 (대한민국 특허제 0492518호, 특허의 명칭: 신종 배무채 변종식물 및 그 육종방법, 등록일: 2005년 5월 23일). 그 후 본 발명자가 확인한 바에 따르면, 이 식물은 싹 채소, 애기채소, 쌈 채소, 열무채소, 김치채소 및 건강보조식품의 원료재료 등으로 널리 이용될 수 있으나, 원연간 잡종이 공통적으로 가지는 두 가지 문제점이 완전하게 해결되지는 못하였음을 알게 되었다.
The present inventors have fostered and patented " Baemuchae ( Genus : xBrassicoraphanus, genome: aarr, 2n = 38)", a genus hybrid of cabbage and radish (Korean Patent No. 0492518, Patent No. Varieties of plants and their breeding methods, registered on May 23, 2005). Then, according to the inventors confirmed, this plant can be widely used as a raw material of sprout vegetables, baby vegetables, ssam vegetables, yeolmu vegetables, kimchi vegetables, and health supplements, etc. It was found that the problem was not completely solved.

첫째 종자 생산성이 낮은 것이다. 이 식물이 비록 농업 경영상 이익이 창출될 정도의 종자가 생산되기는 하지만(400-600L/ha), 한 꼬투리에 10여개의 종자가 들 수 있음에도 1-3개 정도만 영글고 나머지는 중간에 퇴화하여 종자 수량이 적다는 것이다. 둘째 형질이 계속적으로 분리되어 균일성이 비교적 낮다는 사실이다. 농업적으로 실용상 지장 없을 정도의 균일성은 있지만 세대가 거듭되어도 계속해서 특성이 조금씩 분리함으로 채종 재배 때에 형질이 다른 개체를 잘 솎아 주어야 하는 문제점이 확인되었다.
First, seed productivity is low. Although the plant produces seeds that produce agricultural benefits (400-600 L / ha), only about one to three and the other degenerate in the middle, although there are about 10 seeds in one pod. The seed quantity is low. The second is that the traits continue to separate, resulting in a relatively low uniformity. Although there is a uniformity that is practically practical for farming, it has been confirmed that the characteristics of the traits have to be well screened at the time of cultivation, because the characteristics are gradually separated even after generations.

따라서 본 발명은 식물학적으로 기존의 식물들과 같이 꼬투리내의 모든 종자가 퇴화 없이 영글고 적당한 육종적 방법으로 1대잡종 품종의 친으로 이용할 수 있을 정도의 균일성이 보장되는 신 계통을 육성하고 이를 제공하는데 그 목적이 있다. Therefore, the present invention nurtures a new line that guarantees uniformity to the extent that all seeds in the pod can be used as progeny of the first hybrid species without degeneration, as in botanically existing plants. The purpose is to provide.

본 발명의 상기 목적은 돌연변이처리하는 단계와, 채종단계와; 인공교배하여 종자생산성을 확인하는 단계와; AFLP primer를 이용하여 균일성을 확인하는 단계를 통하여 달성하였다.The object of the present invention is the step of mutagenesis, and the step of collecting; Verifying seed productivity by artificial breeding; The uniformity was achieved by using AFLP primer.

본 발명은 배무채의 꼬투리내의 모든 종자가 퇴화없이 영글어 종자생산성이 향상되고 품종 형질이 분리됨이 없이 균일성을 유지하는 뛰어난 효과가 있다.The present invention has an excellent effect of maintaining the uniformity of all seeds in the pods of Baekchae, without any degeneration of the English seed production productivity and separation of the trait trait.

실험 재료 및 방법Materials and Methods

신 계통의 배무채 신품종 식물의 육종방법으로 소포자 돌연변이법을 이용코자하였다. 본 발명자 등에 의해 개발된 소포자 배양에서는 배 발생율이 배양접시 당 0.9개밖에 안되므로(홍과 이, 1995) 돌연변이 유도 수단으로 부적합한 상태이다. 따라서 좀 더 배 발생량이 많은 배양법을 확립함과 동시에 돌연변이제 NMU를 0.01μg/L로 처리하는 시험을 수행하였다. 많은 시험 중 배가 많이 나오는 어떤 한 시험에서 유래된 배를 식물로 유도하고 후대를 채종하였다. 그 결과 종래의 배무채 보다 실내 인공교배에서 채종 량이 많은 개체가 있었다(농림부과제(ARPC), "신 채소작물 배무채의 주요 형질 개선 및 쌈 채소로 연중 생산 연구"의 최종 보고서(2006), 31-38쪽의 표 15-23 참조). NMU(n-nitroso n-methyl urethane)는 분자량이 132로서 반감기가 빠르고 빛에 의해 분해됨으로 소포자 배양 직전에 제조하여 처리한다. 즉 소포자가 배양액 1㎖당 100,000개 들어있는 용액을 먼저 만든다. 그리고 즉시 전등이 꺼진 크린벤치내에서 아래와 같은 과정으로 NMU 농도를 묽게 하여 0.01μM이 되게 배양액에 첨가한다. 그리고 배양액을 2.5㎖씩 직경 60mm petridish에 분주하고 보통의 소포자 배양과정에 준하여 배양한다. 즉 처리중에 NMU를 씻어내지 않고 그대로 두고서 배양하는 것이다.The vesicle mutation method was used as a breeding method for new varieties of Baemuchae new varieties. In the culture of vesicles developed by the present inventors, the embryo development rate is only 0.9 per culture plate (Hong and Lee, 1995), which is inadequate as a means for inducing mutations. Therefore, a more embryonic culture method was established and a test was performed in which the mutant NMU was treated at 0.01 μg / L. Of many tests, pears derived from one of the more pear trials were induced into plants and later seeded. As a result, there were more cultivated individuals in indoor artificial breeding than conventional apricots. See Table 15-23 on page 38. NMU (n-nitroso n-methyl urethane) has a molecular weight of 132 and has a half-life that is rapidly decomposed by light, so it is prepared and processed immediately before vesicle culture. That is, first make a solution containing 100,000 vesicles per ml of culture. In a clean bench with the lamp off immediately, dilute the NMU concentration to add 0.01μM to the culture. Incubate the culture solution in 2.5ml diameter 60mm petridish and incubate following the normal vesicle culture. In other words, the NMU is incubated without being washed off during the treatment.

NMU 농도 희석 과정은 NMU concentration dilution process

- 1M NMU=132㎖ NMU/L H201M NMU = 132mL NMU / LH 2 0

- 10mM(X100희석)용액제조=1.32㎖/L ∴ 0.132㎖=132μl=132p/100㎖ H2010 mM (X100 dilution) solution preparation = 1.32ml / L ∴ 0.132ml = 132μl = 132p / 100ml H 2 0

- 0.1mM(X100희석)용액제조=10mM 용액 1㎖/100mL H20-0.1mM (X100 dilution) solution preparation = 10mM solution 1ml / 100mL H 2 0

- 1.0μM(X희석)용액제조=0.1mM 용액 1㎖/100mL H201.0 μM (X dilution) solution preparation = 0.1 mM solution 1 mL / 100 mL H 2 0

배양액 100mL에 0.1μM NMU용액 1㎖를 혼합하여 0.01 μM 농도로 조정하여 사용하였다.
1 mL of 0.1 μM NMU solution was mixed with 100 mL of the culture solution to adjust the concentration to 0.01 μM.

상기 시험 연구결과에 고무되어 2007년부터 집중적인 연구를 수행한 결과, 먼저 2007년도에 채종량이 많았던 4개체의 후대를 다시 실내 인공교배로 종자 생산능력을 확인하고 가을에는 포장에 재배하여 균일성을 조사하였다. 그리고 다시 2008년도에는 노지 밭에 이들 계통을 재배하여 자연상태에서의 종자생산능력을 확인하였다. 그리고 그 계통들의 균일성을 육안검정만으로는 부족하다고 생각하여 AFLP로 비교하였다. AFLP는 primer를 E-AAC/M-CAA~CGG까지 9개(CAA, CAC, CAG, CCA, CCC, CCG, CCT, CGC, CGG)를 이용하였다.
Encouraged by the above test results, intensive research has been carried out since 2007. First, the seed of four plants, which had a large amount of cultivation in 2007, was re-checked by indoor artificial breeding, and cultivated on the pavement in autumn to ensure uniformity. Investigate. And again in 2008, these strains were grown in open field to identify seed production capacity in the natural state. In addition, the uniformity of the lines was considered insufficient by visual inspection alone, and compared with AFLP. AFLP used 9 primers (CAA, CAC, CAG, CCA, CCC, CCG, CCT, CGC, CGG) from E-AAC / M-CAA to CGG.

균일성 및 종자생산성 확인평가Homogeneity and seed productivity confirmation

종자 생산능력을 확인하기위한 실내교배시험에서 역시 돌연변이제가 처리된 계통은 전년도와 비슷하게 종자가 많이 수확되었다(표 1). In the indoor hybridization test to check the seed production capacity, the mutant-treated line also harvested a lot of seeds similar to the previous year (Table 1).

이들을 가을에 재배한 결과 균일성이 기존 계통보다 훨씬 좋았다. 따라서 이듬해에는 기존계통 2개와 신 계통 4개를 동일한 노지 밭에 재배하여 자연 상태에서 동일한 조건으로 종자생산능력을 비교하였다(표 2 및 도 1 참조). The cultivation of these in autumn resulted in much better uniformity than the existing strains. Therefore, in the following year, two existing lines and four new lines were cultivated in the same open field to compare seed production capacity under the same conditions under natural conditions (see Table 2 and FIG. 1).

Figure pat00002

Figure pat00002

종래 계통 BB1호와 4호는 전체 생산량을 10a당으로 환산하였을 때 약 60L정도로 과거의 시험결과와 아주 비슷하였다. 그런데 돌연변이제가 처리되었던 4계통, BB11호, 12호, 13호, 14호는 100L이상으로 많이 생산되었다. 특히 BB12호는 160L이상으로 무나 배추의 고정종과 비슷한 량이었다. 이러한 결과는 꼬투리안의 종자가 대부분 퇴화하지 않고 영글기 때문임을 사진 1에서 확인할 수 있었다. BB1호와 BB4호는 대부분의 종자가 갈색으로 퇴화하고 있는데 BB#12호는 퇴화하는 종자가 거의 없고 대부분이 아직도 초록색을 띄고 있다. 이렇게 종자생산성은 원연간 잡종임에도 완전히 기존식물과 같이 개량되었다. 즉 원연간 잡종이 가지는 한가 지 문제점이 완전히 해결된 것이다. Conventional systems BB1 and 4 were about 60L when the total production amount per 10a was very similar to the previous test results. However, the four lines, BB11, 12, 13, and 14, which were treated with mutants, were produced more than 100L. In particular, BB12 was more than 160L, similar to the fixed species of radish and cabbage. These results were confirmed in Photo 1 because most of the seeds of the podrian are not degenerated but are English. In BB1 and BB4, most of the seeds degenerate brown, while BB # 12 has few degenerating seeds and most of them are still green. In this way, the seed productivity was completely improved like the existing plants even though it was a hybrid of the first time. In other words, one problem with hybrids is solved completely.

두 번째 문제점인 낮은 균일성에 대하여 염려하지 않을 수 없었으나 실제로 두 번에 걸친 포장재배에서 기존 계통보다 월등히 높은 균일성을 보였다. 즉 외관상으로 볼 때 무나 배추 등의 1대잡종과 거의 비슷한 수준의 균일성을 나타내었다. 이러한 결과를 좀 더 확실하게 증명하고자 AFLP기술을 적용하였다. 한 계통의 모든 공시개체를 AFLP로 전기영동 하였을 때 만일 그들이 모두 동일한 유전자를 가졌다면 그들은 모두 동일한 밴드를 나타낼 것이다. 그리고 한 유전자만이라도 다른 개체가 있으면 그 개체는 다른 개체들과는 다른 밴드, 즉 다형성 밴드를 나타낼 것이다. 이러한 이론에 따라 AFLP를 수행해 본 것인데 예상하였던 것과 같이 균일성이 가장 낮다고 생각되었던 BB4호는 다형성 밴드 율이 5.4%로 그 중 가장 높게 나타났다. The second problem, the low uniformity, was inevitably concerned, but in fact, the packaging in two batches showed much higher uniformity than the existing system. In other words, it showed almost the same level of uniformity as the one hybrid such as radish or Chinese cabbage. In order to prove these results more clearly, we applied AFLP technology. When all the subjects of a line were electrophoresed with AFLP, they would all show the same band if they all had the same gene. And if there is another individual with just one gene, that individual will have a different band, or polymorphic band, than the others. According to this theory, AFLP was performed. As expected, BB4, which was considered to have the lowest uniformity, had the highest polymorphism band rate of 5.4%.

Figure pat00003

Figure pat00003

그런데 기존 보유계통 중 균일성이 가장 좋다고 생각되었던 BB1호는 4.5%로 역시 낮게 나타났다. 그리고 돌연변이제 처리 후 얻어진 계통 중 종자생산성이 획기적으로 개선된 계통들은 4.0%에서 4.9%로 모두 5.0% 이하로 나타났다. 품종의 균일성을 나타내는 기준으로 이 AFLP 기술을 이용하려는 연구가 몇몇 곳에서 있었는데 균일성이 가장 높다는 1대잡종과 그 잡종의 양친까지도 다형성 밴드 율이 재료와 시험시기에 따라 다르지만 대체로 5%까지는 나타나는 경우가 많다고 한다. 따라서 BB1호를 비롯한 BB11호, 12호, 13호, 14호는 외관상으로 나타난 것(도 2 참조)과 동일하게 균일성이 개량되었음을 알 수 있다. 즉 두 번째 문제점인 낮은 균일성도 완전히 해결 된 것이다. However, BB1, which was considered to have the best uniformity among existing holding systems, was also low at 4.5%. Among the strains obtained after the mutant treatment, the strains with dramatically improved seed productivity were 4.0% to 4.9%, all less than 5.0%. Several studies have attempted to use this AFLP technique as a criterion for the uniformity of varieties, with polymorphic band rates varying between material and testing time, even for the first-generation hybrid and the parents of the hybrid, which have the highest uniformity. There are many cases. Accordingly, it can be seen that BB11, 12, 13, and 14, including BB1, have improved uniformity as shown in appearance (see FIG. 2). That is, the second problem, low uniformity, is completely solved.

여기서 변이제가 처리되어 돌연변이 되었을 것으로 생각되는 4개의 계통이 어떻게 변이 제1세대(M1)에서 모든 형질이 고정되어 균일할 수 있느냐하는 의문이 생길 수 있다. 이는 Swanson 등(1989)이 유채의 소포자 배양 때 돌연변이제를 처리하여 제초제저항성 고정계통을 육성할 있었다는 보고에 따라 시험한 결과인 것이다. 즉 소포자를 배양하는 배양액에 돌연변이 유발제를 혼합하여 처리함으로서 반수체인 소포자 내지는 소포자유래 반수성 세포의 분열기에 돌연변이가 생기고 그것이 배로 자라서 식물로 분화하는 과정에 2배체체로 되기 때문인 것이다.
The question arises how the four strains, which are thought to have been treated and mutated, can be fixed and uniform in all traits in the first generation of mutation (M1). This is the result of Swanson et al. (1989) reported that the cultivation of rapeseed vesicles to cultivate mutants to cultivate herbicide-resistant fixed system. That is, by mixing and treating a mutagenizer in a culture medium for culturing the vesicles, a mutation occurs in the divider of the haploid vesicles or the vesicle-derived haploid cells, which grow into embryos and become diploids in the process of differentiation into plants.

이상 설명한 바와 같이, 본 발명은 배추와 무의 원연간 잡종식물 배무채가 소포자 돌연변이라는 육종법으로 종자생산성이 안정화되고 고임성의 신계통을 개량한 뛰어난 효과가 있고 향후 동일한 육종방법으로 배무채의 또다른 신 계통 변종식물을 육성할 수 있는 뛰어난 효과가 있으므로 원예식물육종산업상 매우 유용한 발명인 것이다.
As described above, the present invention has the excellent effect of stabilizing the seed productivity and improving the high-fertility new system by the breeding method of the cabbage and radish of the hybrid plant of the radish is a scavenger mutation. It is a very useful invention in the horticulture plant breeding industry because it has an excellent effect of growing other new strains.
