Description

한국잔디 신품종 용천{Novel grass species Dragon Sky}Novel grass species Dragon Sky

본 발명은 한국잔디 신품종 용천(Dragon Sky)에 관한 것으로, 국내수집 중지계통 간 인공교배 [청북도 연기군 금남면 봉기리 하천변 수집종 (모본) / 충청북도 영동군 심천면 초강리 하천변 수집종 (부본)]하여, 초장이 17 ~ 34 cm, 엽길이가 12 ~ 24 cm, 엽폭이 0.3 ~ 0.5 cm, 포복경의 수(개/6000 cm2)가 5 ~ 29, 포복경의 절간수가 3 ~ 12, 포복경의 길이가 7 ~ 37 cm인 특성을 가지며, 줄기나 뿌리에 의해 영양번식되는 잔디 신품종 용천(Dragon Sky)에 관한 것이다.The present invention relates to a new grass varieties Yongcheon (Dragon Sky), artificial breeding between the domestic collection system [Gongbuk-do Yeonggi-gun Geumnam-myeon Bongi-ri riverside collection species (model) / Chungcheongbuk-do Yeongdong-gun 17-34 cm, leaf length 12-24 cm, leaf width 0.3-0.5 cm, number of creep diameters (dog / 6000 cm 2 ) 5-29, intercution number of creep diameter 3-12, length of creep diameter 7-37 It has a characteristic of cm, and relates to a new breed of grass Sky (Dragon Sky) nourished by the stem or root.

최근에 잔디의 이용이 늘면서 조성 속도가 빠르고 조성 방법이 용이한 품종, 생육 지속 기간이 긴 품종, 종자형 품종 등 각 목적에 부합되는 다양한 품종의 개발이 절실하게 요구되고 있으며, 이러한 요구를 충족시키기 위해 다수의 영양계 신품종들이 등장하고 있다. 또한 한국잔디는 계통마다 종자의 휴면 정도에 차이가 있어 자연발아율이 높은 품종을 육성하는 것이 가능하고(Forbes & Ferguson, J. Am. Soc. Agron., 40:725-32, 1952), 현재 미국에서 'Zenith', 'J37', 'J36' 등과 같이 종자형 품종이 만들어져 보급되고 있다 (Ruemmele & Engelke, Grounds Maintenance, April, 92-126, 1990). Recently, as the use of grass increases, the development of various varieties for each purpose is urgently required, such as varieties which have a high rate of composition and easy to grow, long-lasting varieties, and seed type varieties. Many new varieties of nutrients are emerging. In addition, Korean grass has a different degree of dormancy of seeds in each strain, which makes it possible to cultivate varieties with high natural germination rates (Forbes & Ferguson, J. Am. Soc. Agron., 40: 725-32, 1952). Seed varieties such as 'Zenith', 'J37' and 'J36' have been made and distributed (Ruemmele & Engelke, Grounds Maintenance, April, 92-126, 1990).

한국잔디의 품종 육성은 미국에서부터 시작되었다. 한국잔디가 탐험가들에 의해 아시아지역으로부터 미국으로 들어간 시기는 1895년부터 1900년 초 사이로 보고되고 있다 (Ruemmele & Engelke, Grounds Maintenance, April, 92-126, 1990; Christians & Engelke, Choosing the right grass to fit the environment. p.99-113. In: A.R. Leslie (ed.). Integrated pest management for turf and ornamentals, CRC Press, Levis Publishers, 1994). 그 당시 미국의 잔디 육종가들은 잎이 거친 들잔디(Z. japonica), 잎이 매우 가늘고 내한성이 약한 비단잔디(Z. tenuifolia), 그리고 이들의 중간적 특성을 보이는 금잔디(Z. matrella)가 잔디로서의 가능성이 있다고 판단했으며, 내염성이 강한 갯잔디(Z. sinica)와 왕잔디(Z. macrostachya)는 잔디 관리자들로부터 호응을 얻지 못했다.Breeding of Korean grass began in the United States. It is reported that korea grasses entered the United States from Asia by the explorers between 1895 and early 1900 (Ruemmele & Engelke, Grounds Maintenance, April, 92-126, 1990; Christians & Engelke, Choosing the right grass to fit the environment.p. 99-113.In: AR Leslie (ed.). Integrated pest management for turf and ornamentals, CRC Press, Levis Publishers, 1994). At that time, grass breeders in the United States showed the possibility of grassy grass ( Z. japonica ), silk grass ( Z. tenuifolia ) with very thin and cold-tolerant leaves, and gold grass ( Z. matrella ) with their intermediate properties. It was judged that there was a strong flame resistant Z. sinica and Z. macrostachya did not get the response from the grass managers.

그러한 이유로 미국에서 처음으로 선발된 계통은 금잔디 계통 중 잎이 곱고, 밀도가 높은 형태인 FC13521이었다. 그러나 FC13521 은 내한성이 낮아(Beard, J.B., Turfgrass: Science and Culture. Pretice-Hall, Inc., Englewood Cliffs, N.J. p.132-147&511, 1973), 그 이용이 줄어들었으며, 그 이 후 1951년 들잔디로부터 선발된 'Meyer'가 내한성, 진한 녹색, 중엽형의 특성을 보이며 우수한 잔디로 이용되었다. 1955년에는 미국 농무성에서 들잔디와 비단잔디를 인공교배해서 만든 F1 교잡종인 'Emerald'가 개발되었다. 'Emerald'는 들잔디의 특성중 하나인 내한성 과 비단잔디의 특성인 높은 밀도의 특성을 공유해 우수한 잔디로 평가되었으나, 내병성이 약하다는 단점을 보였다.For that reason, the first of its kind in the United States was FC13521, a multi-leaf, dense form of the grass family. However, FC13521 has low cold resistance (Beard, JB, Turfgrass: Science and Culture.Pretice-Hall, Inc., Englewood Cliffs, NJ p.132-147 & 511, 1973), and its use has declined since then in 1951. The selected 'Meyer' was used as an excellent lawn with cold resistance, dark green color, and mesenchymal characteristics. In 1955, the US Department of Agriculture developed 'Emerald', an F1 hybrid made from artificial crosses of grass and silk grass. 'Emerald' was evaluated as an excellent grass by sharing cold resistance, which is one of the characteristics of field grass, and high density, which is the characteristic of silk grass, but showed weakness of resistance to disease.

국내에서는 1965년부터 서울대학교에서 한국잔디 연구가 시작되었으며, 콜히친(colchicine)처리에 의한 돌연변이 유도에 관한 연구가 보고되었고(Lim, Y.P., Studies on the colchicine induced mutant in zoysiagrass (Zoysia japonica Steud.), MS Thesis, Seoul National University, 1982), 인공교배를 통해 종간 교배가 가능함을 확인하였다 (Hong & Yeam, J. Kor. Soc. Hort. Sci. 26(2):169-78, 1985). 이들은 한국 잔디류는 5종간에 교배 화합성이 있으며, 종간교잡종들은 형태적인 특성에 있어 대부분 양친의 중간형을 나타내었고, 생육속도에 있어서는 잡종강세 현상을 나타내었다고 보고하였으며, 다수의 인공교배 계통을 작성하였다. In Korea, research on Korean grass began at Seoul National University in 1965, and studies on the induction of mutations by colchicine treatment (Lim, YP, Studies on the colchicine induced mutant in zoysiagrass ( Zoysia japonica Steud.), MS Thesis, Seoul National University, 1982), and it was confirmed that cross-breeding is possible through artificial breeding (Hong & Yeam, J. Kor. Soc. Hort. Sci. 26 (2): 169-78, 1985). They reported that Korean grasses were hybridized between five species, and hybrids among the hybrids showed the middle type of both parents in morphological characteristics and hybrid stresses in the growth rate. Created.

이후, 서울대학교에서 육성한 수집 및 인공교배계통 중 47계통을 1990년 단국대학교에서 분양 받아 잔디육종을 시작했으며, 1991년과 1992년에 걸쳐 한반도의 남해안과 서해안에서 총 93개의 지역종을 수집하여, 유전자원을 확보하였다. 이들 수집계통을 동위효소 분석과 RAPD 분석을 통해 한국잔디의 기본 5종의 특성을 확인하였으며(Yang, et al., 한국원예학회지 36(2):240-7, 1995; Choi, et al., 한국원예학회지 38(4):399-407, 1997; Choi, et al., J. Kor. Soc. Hort. Sci. 38(6):789-95, 1997), 이를 기본으로 하여, 선발, 인공교배, 합성품종, 형질전환 등의 방법으로 한국잔디를 육성하여 왔다. Since then, 47 of the collection and artificial breeding systems fostered at Seoul National University were distributed by Dankook University in 1990, and grass breeding began.In 1991 and 1992, 93 species were collected from the south coast and west coast of the Korean Peninsula. , Secured genetic resources. These collections were characterized by isoenzyme and RAPD analysis (Yang, et al., Korean Society for Horticultural Science 36 (2): 240-7, 1995; Choi, et al., Journal of the Korean Society for Horticultural Science 38 (4): 399-407, 1997; Choi, et al., J. Kor. Soc. Hort. Sci. 38 (6): 789-95, 1997). Korean grass has been cultivated by breeding, synthetic breeding, and transformation.

한국잔디는 다년생 초본류로 화본과에 속하며, 포복경 및 지하경을 가지고 번식하는데 지역에 따라 형태나 특성에 있어 많은 변이를 나타내고 있다. 지금까지 의 연구에 의하면 한국에는 들잔디 (Z. japonica), 금잔디 (Z. matrella), 비로드 잔디 (Z. tenufolia), 갯잔디 (Z. sinica), 왕잔디 (Z. macrostachya)등 5-6종의 잔디가 분포되어 있는 것으로 보고 되고 있다. 한국잔디는 난지형잔디로서 한국을 포함한 극동아시아에 널리 자생하고 있으며, 정원, 공원, 경기장, 골프장, 도로비탈면, 간척지, 공항 등 거의 모든 장소에서 이용되고 있다. 특히, 한국잔디는 우리나라 기후에 있어 가장 적합한 잔디이며, 다른 한지형 양잔디 및 다른 난지형 잔디보다도 환경적응성이 뛰어나다. 특히 내건성, 내답압성, 내한성, 내서성, 내염성등이 강한 것으로 알려져 있다. 그러나, 잔디 조성이 늦고, 녹색기간이 짧은 등의 단점을 가지고 있어 그에 따른 우수한 품종에 대한 육종이 요구되어지고 있다.Korean grass is a perennial herbaceous plant belonging to the flower family, and it breeds with crawling and underground diameters and shows many variations in form and characteristics depending on the region. Studies so far deuljandi (Z. japonica), Jandi (Z. matrella) in Korea, velvet grass (Z. tenufolia), Conger grass species, such as 5-6 (Z. sinica), wangjandi (Z. macrostachya) Grass is reported to be distributed. Korean turf is a non-turquoise grass that grows widely in Far East Asia, including Korea, and is used in almost all places such as gardens, parks, stadiums, golf courses, road slopes, reclaimed land, and airports. In particular, Korean grass is the most suitable grass in Korea's climate, and it is more environmentally compatible than other cold grass and other warm grass. In particular, it is known to be strong in dry resistance, pressure resistance, cold resistance, weather resistance and flame resistance. However, there is a disadvantage in that the composition of the grass is slow, the green period is short, and breeding for excellent varieties is required accordingly.

1992년 생물다양성 협약을 계기로 세계 각국이 유전자원의 중요성을 보다 심각하게 인식하기 시작하였고, 우수한 유전자원은 물론, 그의 성능이나 특성이 미처 밝혀지지 않은 유전자원도 나라밖의 반출이나 분양이 갈수록 어려워지고 있다.In 1992, with the Convention on Biological Diversity, countries around the world began to recognize the importance of genetic resources more seriously.In addition to excellent genetic resources, gene sources whose performance or characteristics are not known are increasingly difficult to export or sell outside the country. ought.

12월 생물다양성 국제 협약이 발효된 이후 세계 각국은 앞다투어 자국의 종자를 챙기기에 바빴다. 생물다양성 협약이 각국의 고유종자에 대한 소유권을 인정해주기 때문이었다.Since the international agreement on biodiversity came into force in December, countries around the world have been busy gathering their seeds. This is because the Convention on Biological Diversity recognizes the ownership of endemic seeds in each country.

상기 잔디 중 우리나라의 골프장, 경기장, 공원 등에 이용되는 잔디종은 대부분 들잔디이고, 남부지방에서는 금잔디도 일부 사용되고 있으나, 체계적으로 선발되어 육종된 품종은 거의 개발되지 않은 상태이다. Among the grasses, most of the grass species used in golf courses, stadiums, and parks of Korea are grass turf, and some of the grass is used in the southern region, but the varieties that have been systematically selected and breeded are almost undeveloped.

미국과 일본 등의 선진국들이 발 빠르게 우리나라와 동남아시아의 우수한 특성을 보이는 잔디를 수집하고, 이를 이용하여 잔디육종을 수행하고, 우수한 품종을 세계 각국에 판매하여 국제시장에서 우위를 점유하고 있는 데 반하여, 우리나라의 경우는 현재 시장에서 유통되고 있는 한국잔디의 대부분이 임의로 선발하여 증식시킨 것이 대부분이기 때문에, 품종의 구분도 명확하지 않고, 여러 종류의 잔디가 무분별하게 섞여 있어, 균일성도 떨어진다. 또한, 최근에는 외국에서 수입된 잔디가 싼 가격에 유통되고 있어서, 한국 잔디 시장경쟁력을 저하시키고 있다. 따라서, 우수한 유전형질과 생육특성을 보이는 한국잔디를 수집하고 이를 이용하여 우수한 특성을 보이는 잔디를 육성하는 것이 시급히 요구되고 있다.While developed countries such as the United States and Japan are rapidly collecting grasses that show excellent characteristics of Korea and Southeast Asia, they use them to carry out grass breeding, and sell superior varieties to countries all over the world to gain an advantage in the international market. In Korea, most of the Korean grass currently in the market is randomly selected and multiplied. Therefore, the classification of varieties is not clear, and various types of grass are mixed indiscriminately, resulting in poor uniformity. In addition, in recent years, grass imported from foreign countries is being distributed at a low price, thus degrading the competitiveness of the Korean grass market. Therefore, it is urgently required to collect grass of Korea having excellent genetic traits and growth characteristics and to cultivate grass having excellent characteristics using the same.

생육 및 생태학적 특성조사는 식재되어있는 재배환경에 따라 변이가 있음으로 유전적으로 고정된 유전체정보를 기초로 한 분자마커의 개발이 필수적이며, 분자마커개발 방법에 있어서도 안정적으로 재현성이 있는 마커 시스템을 이용해야한다. 따라서 잔디의 품종 구별을 위하여 생육 생태학적 특성조사 및 안정적 분자마커의 종합적 정보가 함께 제공되어야한다.As the growth and ecological characteristics are varied according to the planting environment, it is essential to develop molecular markers based on genetically fixed genome information, and to develop a marker system that is stably reproducible in the method of developing molecular markers. Should be used. Therefore, comprehensive information on growth ecological characteristics and stable molecular markers should be provided to distinguish grass varieties.

RAPD (Random Amplified Polymorphic DNA, Williams JGK et al., 1990, DNA polymorphism amplified by arbitrary primers are useful as genetic markers., Nucleic Acids Res., 18:6531-6535)는 최초의 PCR-based marker 라고 할 수 있는데, 이는 genomic DNA 상에서 약 10-mer 로 구성된 primer 와 일치된 부분을 PCR 에 의해 증폭된 DNA 분석하는 마커이다. 이는 RFLP (Restriction Fragment Length Polymorphism)와는 달리 증폭된 DNA 량이 충분하여 radioisotope 혹은 chemically-labelled 된 probe 를 필요로 하지 않고, 분리된 gel 상에 ethidium bromide 를 처리하여 hybridization 과정 없이 DNA 변이를 분석할 수 있는 방법이다. RAPD (Random Amplified Polymorphic DNA, Williams JGK et al., 1990, DNA polymorphism amplified by arbitrary primers are useful as genetic markers., Nucleic Acids Res., 18: 6531-6535) is the first PCR-based marker. This is a marker that analyzes DNA amplified by PCR on a portion corresponding to a primer consisting of about 10-mer on genomic DNA. Unlike RFLP (Restriction Fragment Length Polymorphism), the amount of DNA amplified is sufficient, so it is not necessary to use radioisotope or chemically-labelled probe, and ethidium bromide is treated on the separated gel to analyze DNA variation without hybridization process. to be.

그 결과 신품종 용천(Dragon Sky)은 봄철녹화속도와 피복률에 있어서, 타 잔디류와 비교해서 봤을 때 평균치로 보였고, 색상은 약간 짙은 편에 속하는 것으로 조사되었다. 이삭출현 시기는 5월 중순부터 6월 초순이었고, 휴면 시기는 다소 느린 편이였다. Genetic color 는 짙은 녹색을 갖고, Fall color와 winter color 는 대부분 비슷한 경향을 가지며, 용천의 경우는 안양, 장성, 또는 들잔디와 비슷한 경향을 띠었다. SK중지가 가장 빨리 휴면기로 들어가면서 잎의 탈색이 진행되었고, 제니스는 잎의 녹색을 가장 오랫동안 유지하였다. 용천중지의 경우 Leaf Texture는 타 잔디류에 비해서 약간 부드러운 편이며, 종자의 길이와 너비는 평균정도 되지만 무게는 가장 적게 나가는 것으로 조사가 되었다.As a result, the new Dragon Sky was shown as an average value compared with other grasses in terms of spring greening rate and coverage, and the color was slightly darker. Isaac emerged from mid-May to early June, and the dormancy was rather slow. Genetic color is dark green, Fall color and winter color tend to be similar, and Yongcheon tends to be similar to Anyang, Great Wall or Grass. As the stop of SK entered the dormant phase, the leaves decolorized, and Zenith kept the leaves green for the longest time. In the case of Yongcheon Jungji, Leaf Texture is slightly softer than other grasses, and the length and width of seeds are average but the weight is the lowest.

시험포장 Ⅲ(반지름 10 cm 원모양)은 2003년 10월 9일 대전의 삼덕조경(주) 의 농장에서 임의로 선정한 17곳의 신품종 용천(Dragon Sky)을 sampling 하여 시험하였다. 각각의 조사항목은 기존의 국내 잔디품종의 특허출원 시 첨부된 조사 항목 이외에 미국의 NTEP (National Turfgrass Evaluation Program)의 잔디평가항목을 참고해서 국제적 신뢰성 있는 조사가 되도록 하였다. 조사는 크게 계절별로 시행이 되었고, 2003년 10월에 잔디가 식재되어 휴면기에 들어감으로써 2004년 봄부터 체계적인 조사를 시작하였다.The test packaging Ⅲ (round 10 cm radius) was tested by sampling 17 new varieties of Dragon Sky chosen at the farm of Samdeok Landscaping Co., Ltd. in Daejeon on October 9, 2003. Each survey item was referred to the National Turfgrass Evaluation Program (NTEP) turf evaluation item in addition to the investigation item attached to the patent application of the existing domestic grass varieties. The survey was carried out seasonally, and in October 2003, the grass was planted and entered the dormant period.

시험포장Ⅲ에서는 신품종 용천(Dragon Sky)간의 변이성을 살펴보았다. 본 포장에서는 신품종 용천(Dragon Sky)간에 있어서 유전적 균일성을 확인하고 대표 종을 선발하기 위함이다. 신품종 용천(Dragon Sky)간에 있어서 형태적 변이는 다소 다양하게 나타났으나, 잔디의 재배 상 지역적 조건, 기후적 여건, 그리고 교배상황에 따라서 여러 가지의 상황이 만들어지기 때문에 신품종 용천(Dragon Sky)이 아닌 다른 잔디류에 있어서도 이런 경향을 띠고 있는 것으로 나타났다. 신품종 용천(Dragon Sky) 전체 sample 을 통하여 유전적으로 판단을 하였고, 신품종 용천(Dragon Sky)간 통계적 유의성이 없기 때문에 동일종으로 조사되었다(표5). Test Package III examined the variability between the new varieties Dragon Sky. The purpose of this package is to check genetic uniformity among new breed Dragon Sky and to select representative species. The morphological variation between the new varieties Dragon Sky is somewhat different, but since the various conditions are created depending on the regional conditions, climatic conditions, and mating conditions, the new breed Dragon Sky is created. This trend also appears in other grasses. Genetic judgments were made through the entire sample of Dragon Sky, and the same species was investigated because there was no statistical significance between Dragon Sky.

실시예Example 4. 신품종  4. New varieties 용천(Dragon Sky)와With Dragon Sky 타 품종간 조사 항목별로 통계분석 Statistical analysis by survey items among different breeds

시험포장 Ⅰ에서 조사된 항목별로 자료를 수집했으며 수집된 데이터는 Statistical Analysis System (SAS Institute Inc., Cary, NC) package 를 이용해서 통계분석하였다. 분산분석법은 PROC ANOVA procedures 를 사용한 데이터로 근거하였다. 또한 다른 조사항목 사이의 유의수준은 최소유의차검정[Least Significant Difference (LSD)]에 따랐으며 상관관계는 PROC CORR procedures 를 이용하였다.Data were collected for each item examined in Test Package I. The collected data were statistically analyzed using the Statistical Analysis System (SAS Institute Inc., Cary, NC) package. Analysis of variance was based on data using PROC ANOVA procedures. In addition, the significance level among the other survey items was according to the Least Significant Difference (LSD), and the correlations were the PROC CORR procedures.

각각의 특징인 초장[plant height (PH)], 엽폭[width of leaf (WOL)], 엽길이[length of leaf (LOL)], 이삭/꽃대의 수[number of flower (NOF)], 이삭길이[length of inflorescence (LOI)], 꽃대(이삭포함) 길이[length of peduncle (LOP)], 이삭당 종자수 [number of spikes per inflorescence (NSPI)], 포복경의 길이[length of stolon (LOS)], 포복경의 수[number of stolon (NOS)], 포복경의 절간수[number of internode (NOI)]를 통계처리 하였으며 각 잔디별로 30개체씩 조사한 평균값은 아래와 같다(표 6).Plant height (PH), width of leaf (WOL), length of leaf (LOL), number of flower (NOF), ear length length of inflorescence (LOI), length of peduncle (LOP), number of spikes per inflorescence (NSPI), length of stolon (LOS) The number of stolons (NOS) and number of internodes (NOI) were statistically analyzed. The average values of 30 grasses per lawn were as follows (Table 6).

Duncan′s test 에서 나온 결과로 신품종 용천(Dragon Sky)과 다른 잔디들 사이에 그룹핑이 가능한 것으로 나왔다. 다른 품종들과 눈에 띄게 그룹핑이 가능하 지는 않았지만 여러 조사항목별로 타 잔디류와 다른 그룹핑이 가능하였다. 신품종 용천(Dragon Sky)을 제외한 다른 잔디들와 이와 비슷한 결과가 나왔으며 조사 항목별로 판단했을 때 각각 다른 품종인 것을 확인할 수 있는 자료가 되었다(표 6). The results from Duncan's test indicate that grouping is possible between the new breed Dragon Sky and other grasses. Although it was not possible to group noticeably with other varieties, it was possible to group differently from other grasses by various survey items. Similar results were obtained with other grasses except for the new breed Dragon Sky, and the data were identified as different varieties when judged by the survey items (Table 6).

또한 위의 실시예 2에서 나온 결과와 같이 90개체(30개체 × 3반복)를 비교했을 때도 신품종 용천(Dragon Sky)은 다른 중지류에 비해 포장은 짧고 엽길이와 잎폭이 약간 긴 편으로 나왔다. 또한 포복경의 길이는 보통이지만 포복경의 길이에 비해 많은 절간을 가지고 있음으로써 단위 피복률의 조밀도가 다른 잔디보다 높은 결과가 나왔다(표 7).In addition, when comparing 90 objects (30 objects × 3 repetitions) as shown in Example 2 above, the new breed Dragon Sky showed a shorter pavement and a slightly longer leaf length and leaf width than other middle class species. In addition, although the length of the creep diameter is normal, it has more intercutions than the length of the creep diameter, resulting in higher density of unit coverage than other turfgrass (Table 7).

또한 잔디별로 조사항 항목들간의 상관관계를 살펴본 바에 의하면 꽃대(이삭포함) 길이(LOP)와 이삭당 종자수(NSPI) 사이에서 특별한 상관관계가 있으며(r = 0.85787***), 이삭길이(LOI)는 꽃대(이삭포함) 길이(LOP) 및 이삭당종자수(NSPI)와 특별한 상관관계가 있었다(r = 0.89151***, 0.87692***). 또한 포복경의 길이(LOS)와 포복경의 수(NOS)가 상관관계가 있으며(r = 0.82**), 포복경의 수(NOS)와 포복경의 절간수(NOI)도 상관관계가 있는 것으로 결과를 얻었다(r = 0.66**). 위의 통계결과로 판단했을 때 실시예 2의 신품종 용천(Dragon Sky)과 타 잔디류간의 조사항목 결과를 신뢰할 수 있을 것으로 본다(표 8). In addition, according to the correlation between the items of each grass, there is a special correlation between the length of the stalk (including ear) (LOP) and the number of seeds per ear (NSPI) (r = 0.85787 ***) and the length of the ear ( LOI) had a special correlation with the pedicle length (including ear) (LOP) and the number of ear sugar seeds (NSPI) (r = 0.89151 ***, 0.87692 ***). In addition, there was a correlation between the length of the laparotomy (LOS) and the number of laparotomy (r = 0.82 **), and the number of laparotomy (NOS) and the number of intercutaneous laparotomy (NOI) were correlated. (r = 0.66 **). Judging from the above statistical results, it is believed that the results of the survey items between the new varieties Dragon Sky and other grasses of Example 2 may be reliable (Table 8).

위의 RAPD 결과물 중 OPW-2(5'-ACCCCGCCAA-3') 에서 특히 용천중지만의 고유의 band 를 확인할 수 있었다. Among the above RAPD results, OPW-2 (5'-ACCCCGCCAA-3 ') was able to identify the unique bands, especially in Yongcheon.

OPW-2 의 1244 bp 에 있는 RAPD bands 는 다른 잔디류에서 보이지 않는 용천중지만의 고유의 RAPD bands 를 보여주고 있기 때문에 이들 마커를 신품종 용천(Dragon Sky)의 특이 RAPD 마커로 확인하였다(도 5).Since RAPD bands at 1244 bp of OPW-2 show unique RAPD bands of only Yongcheon medium that are not seen in other grasses, these markers were identified as specific RAPD markers of new breed Dragon Sky (Figure 5). .

추가로 2차 RAPD 는 60개의 Operon Primer 로 진행하였으며 진행한 방법은 다음과 같다. 실시예 5의 근연관계 분석 결과 가장 근연관계인 3개체(DS 9-1, DS 11-2, DS 12-2)를 타 잔디들[안양중지, 장성중지, SK중지(가칭), 건희, 제니스, 조이시아 코리아나(Z. koreana), 고려잔디(Z. matrella, PI231146, PI264343), 갯잔 디(Z. sinica, PI 553019), 왕잔디(Z. macrostachya, PI 553020), 들잔디(Z. japonica, PI 338566)]과 RAPD를 통하여 비교를 하였다. 사용된 primer 는 QIAGEN사의 Operon 10-mer Primers (OPA series, OPC series, OPD series 각각 20개) 60개를 사용하였고, PCR band 의 유무에 따라서 1과 0으로 coding 을 하였다. Coding 된 결과는 NTSYSpc2 를 이용하여 신품종 용천(Dragon Sky) 대표종과 타 잔디류간의 근연관계를 살펴보았다(표 12, 13).In addition, the second RAPD was performed with 60 Operon Primers. As a result of the relationship analysis of Example 5, grasses [Anyang, Jangseong, SK, (tentative name), Kun-hee, Zenith, riding the three most closely related objects (DS 9-1, DS 11-2, DS 12-2) Zosia Koreana ( Z. koreana ), Goryeo grass ( Z. matrella , PI231146, PI264343), Gaedan di ( Z. sinica , PI 553019), Wang turf ( Z. macrostachya , PI 553020), Wild grass ( Z. japonica , PI 338566 )] And RAPD. The primers used were 60 Operon 10-mer Primers (20 each of OPA series, OPC series, and OPD series) of QIAGEN, and were coded as 1 and 0 depending on the presence or absence of PCR bands. Coding results were examined using NTSYSpc2 to examine the relationship between new species Dragon Sky representative species and other grasses (Tables 12 and 13).

근연관계의 결과로 인해 신품종 용천(Dragon Sky)과 타 잔디류와의 유전적 차이성이 있다는 것을 검증할 수 있었다. PCR product 내 band 의 존재 유무에 따라 coding 을 했으며 NTSYSpc version 2.0 을 이용하여 근연관계를 분석한 다음 신품종 용천(Dragon Sky)과 다른 잔디들간의 상호 유전연관성을 비교한 결과 신품종 용천(Dragon Sky) 대표종 3계통은 다른 Zoysiagrass 류와 다른 품종으로 확인되었다.As a result of the close relationship, it was possible to verify the genetic difference between the new species Dragon Sky and other grasses. Coded according to the presence or absence of band in PCR product, NTSYSpc version 2.0 was used to analyze the relationship and then compared the genetic correlation between the new species Dragon Sky and other grasses. Three strains have been identified from other Zoysiagrass species.

또한 OPA-8 의 primer를 사용했을 때 신품종 용천(Dragon Sky) 대표종의 3개체에서만 볼 수 있는 polymorphic band를 확보할 수 있었다(도 6).In addition, when using the primer of OPA-8, it was possible to obtain a polymorphic band that can be seen only in three species of the representative species of new species Yongcheon (Dragon Sky) (Fig. 6).

이상 실시예에서 확인된 바와 같이, 본 발명의 신품종 잔디 용천(Dragon Sky)은 생육 형태적, 분자유적학적으로 타 잔디 품종 및 계통들과 구별된다. 또한 국내에서 재배하고 있는 다른 난지형 잔디들과 비교할 때 품질, 색상 및 영양번식상태가 우수하고, 피복률이 높고, 조밀도가 크기때문에 국내 각종 골프장, 공원, 절개지, 또는 녹화 사업 등에 활용될 수 있는 특징이 있다. As confirmed in the above examples, the new breed Dragon Grass (Dragon Sky) of the present invention is distinguished from other grass varieties and lineages in growth morphology, molecular history. In addition, it has excellent quality, color and nutritional propagation status, high coverage and high density compared to other cultivated turf, which can be used in various golf courses, parks, incisions or greening projects in Korea.
