There are some international standards and organization controling the quality characteristics of varieties and seeds such as UPOV, OECD, ISTA, AOSA. The National List system to check variety performance such as quality characteristics of plant varieties and seeds was established by each countries. The UPOV (International Union for the Protection of New varieties of Plant) regulates the requirement of plant variety protection that is distinctness (D), uniformity (U), stability (S) (here in after called DUS), Novelty and Denomination, and some quality characteristics are used to examine the requirement of plant variety protection by each crops. OECD (Organization for Economic Cooperation Development) seed scheme regulates the seed certification for seed trade between countries. ISTA (International Seed Testing Association) and AOSA(Association for Official Seed Analyst) regulates the seed analysis standard and methods. Most of the countries in Europe has the National List system, which check the value for cultivation and use(VCU), that is to say, variety performance such as yield, quality and stress to environment. All the seeds should be enlisted in the National List before sell the seed in their country. All the quality characteristics checked variety performance are for instance, amylose and amylopectin content in rice, molting quality, $\beta$-glucan, protein in barley, protein and sugar content in soybean, sugar and amylopectin content in corn etc. Conditions for the protection of new variety of plant are DUS. Quality characteristics may be the important characteristics and used to check DUS in crop by crop. It is very important to develop a new characteristics and establish standard method fur examine the VCU and DUS test for each crop.

국내 화훼류 육성품종의 미국 출원에 대한 안내 및 미국 육성 품종의 국내 출원 시 품종보호심사에 활용하는 자료로 제공하고자 미국의 식물신품종보호제도와 식물특허에 대한 운영실태를 조사하였다. 미국은 신품종 대상에 따라 종자번식 품종과 괴경식물은 식물신품종보호법으로, 무성번식품종은 식물특허로 구별되어 보호를 받게 된다. 품종보호나 특허를 받기위한 조건은 신규성, 구별성, 균일성, 안정성이며, 과수나 묘목의 품종보호 보호기간은 25년이고 나머지 대상의 품종보호와 식물특허의 보호기간은 20년이다. 식물신품종보호와 식물특허의 심사 모두 재배심사나 현지심사를 하지 않고 출원인이 제출한 서류만으로 심사를 한다. 화훼류 출원은 영양체번식 품종의 식물특허 출원이 대부분이고 종자번식 품종의 품종보호 비율은 낮으며, 전체 식물특허 출원 중 화훼류가 87%를 차지하며, 자국과 외국간 출원 품종수에는 큰 차이가 없다.

Rice blast disease caused by Magnaporthe grisea (Hebert) Barr [teleomorph] is one of the most devastating diseases in rice plantation areas. Silicon is considered as a useful element for a large variety of plants. Rice variety MR219 was grown in the glasshouse to investigate the function of silicon in conferring resistance against blast. Silica gel was applied to soil while sodium silicate was used as foliar spray at the rates of 0, 60, 120, 180 g/5 kg soil and 0, 1, 2, 3 ml/l respectively. The treatments were arranged in a completely randomized design. Disease severity and silicon content of leaves were compared between the non-amended controls and rice plants receiving the different rates and sources of silicon. Silicon at all rates of application significantly (${\alpha}$ = 0.05) reduced the severity of disease with highest reduction (75%) recorded in treatments receiving 120 g of silica gel. SEM/EDX observations demonstrated a significant difference in weight concentration of silicon in silica cells on the leaf epidermis between silicon treated (25.79%) and non treated plants (7.87%) indicating that Si-fertilization resulted in higher deposition of Si in silica cells in comparison with non-treated plants. Application of silicon also led to a significant increase in Si contents of leaves. Contrast procedures indicated higher efficiency of silica gel in comparison to sodium silicate in almost all parameters assessed. The results suggest that mitigated levels of disease were associated with silicification and fortification of leaf epidermal cells through silicon fertilization.

This study was carried out to assess the potential of SSR markers for variety identification by comparing SSR markers and morphological traits in tests of distinctiveness, uniformity, and stability (DUS) of pepper (Capsicum annuum L.) varieties. Twenty-seven SSR markers were polymorphic in 66 pepper varieties, revealing a total of 89 alleles. Average polymorphism information content (PIC) value was 0.529, ranging from 0.03 to 0.877. Cluster analysis of the band patterns separated the varieties into three groups corresponding to varietal types. Morphological trait-based clustering showed some degree of similarity to dendrogram topologies based on the SSR index. However, no significance correlation was found between the SSR and morphological data. SSR markers could be used to complement a DUS test of a candidate variety and to select complimentary varieties by pre-screening existing varieties in the context of protecting new varieties of pepper.

The National Forest Seed and Variety Center aims to write a manual for cultivation and characteristic inspection of new seed varieties in Korea, serving dual purposes. The first is the enhancement of the test guidelines, particularly the distinctness, uniformity and stability (DUS) test, for new seed variety, where research and examination are conducted based on the test guidelines. However, if the crop-specific test guidelines are initially reorganized, the details are unclear. Therefore, it seeks to maintain a written record to prevent confusion when the person in charge is changed. The second is to encourage the development of new varieties. By incorporating general characteristics and cultivation techniques in the manual, it seeks to encourage breeders to develop new varieties. Additionally, it serves as an important chronological record of the creation process, thereby helping future manual authors. This article introduces the current status of new plant variety protection and outlines the significance of creating a manual for cultivation and characterization of Actinidia arguta for screening new varieties.

본 연구는 국제 식물 신품종 보호제도가 실시된 이후 나라꽃 무궁화의 국내외 개발 동향을 조사 분석하고, 향후 나라꽃 무궁화를 국내 보급 확대뿐만 아니라, 해외수출을 촉진시키고, 활용범위를 넓히기 위한 기초 자료로 이용하고자 하였다. 국내에서 개발된 무궁화 품종 중 2004년부터 2018년까지 국립종자원에서 품종보호권 번호를 획득한 품종은 총 97개였다. 국내 육성 품종 중 꽃이 특이한 품종들은 정원 내 초점식재용으로 활용이 가능하였으며, 수세가 강하고 키가 큰 교목성 품종들은 가로수 및 초점식재용으로, 가지의 배열이 조밀하고 키가 작은 왜성형은 분화 및 분재용으로 이용되었다. 국내 품종보호권을 획득한 품종들은 대부분 홑꽃이었으며, 반겹꽃 품종은 2개, 겹꽃 품종은 전혀 없었다. 꽃색의 경우, 꽃잎이 분홍으로 단심이 있는 품종이 57개로 가장 많았으며, 흰색 꽃잎에 단심이 있는 품종이 21개로 많았다. 국내 품종보호권을 획득한 품종 중 교잡육종법으로 개발된 품종이 61개로 가장 많았으며, 다음으로 종간 교배육종을 통해 육성된 품종이 23개, 방사선 처리와 돌연변이 육종으로 개발된 품종이 7개였다. 미국 특허청(USPTO)에 출원한 무궁화 품종은 미국, 영국, 네델란드에서 각각 7개로 가장 많았으며, 다음은 한국에서 4개 품종, 벨기에에서 3개 품종이 등록되어 총 34 품종이었다. 유럽공동체 식물품종사무국(CPVO)에 등록한 무궁화 품종은 프랑스에서 육성된 품종이 16개 품종으로 가장 많았으며, 다음은 네델란드에서 9개 품종, 영국에서 5개 품종, 벨기에에서 1개 품종으로 총 32 품종이었다. 미국과 캐나다에서 동시에 식물 특허 및 식물 육성자 권리를 받은 품종은 'America Irene Scott', 'Antong Two', 'CARPA', 'DVPazurri', 'Gandini Santiago', 'Gandini van Aart', 'ILVO347', 'ILVOPS', 'JWNWOOD 4', 'Notwood3', 'RWOODS5', 'SHIMCR1', 'SHIMRR38', 'SHIMRV24', 'THEISSHSSTL' 등 15 품종이었다. 국내 품종보호권과 해외 식물 특허를 동시에 취득한 품종으로 'SHIMCR1'과 'SHIMRV24'이 있었다. 미국 식물 특허와 유럽 신품종보호권을 동시에 받은 무궁화 품종은 총 14 품종이었다. 미국 식물 특허권을 획득한 무궁화 품종 중 겹꽃 품종이 18개(52.9%), 반겹꽃이 4개(11.8%), 홑꽃 품종이 12개(35.3%)로 나타나 겹꽃 품종이 많았으며, 유럽 품종보호권을 획득한 무궁화 품종에서도 겹꽃 품종이 11개(34.3%), 반겹꽃이 7개(21.9%), 홑꽃 품종이 14개(43.8%)로 나타나 미국과 같은 결과를 보였다. 향후 나라꽃 무궁화의 품종은 국내 보급 확대 및 해외 수출을 위해서는 꽃의 종류가 홑꽃에서 겹꽃 품종의 개발이 요구되어지며, 꽃색 또한 적색, 청색 등 다양해야 할 것이다. 또한 무궁화 품종의 신품종 개발 시 미국 및 유럽품종처럼 화단 지피용 및 가장 자리식재용으로 이용하기 위해 키가 작고 가지가 아래로 향하는 품종 개발이 요구되어야 할 것이다. 또한 키가 작고 마디의 길이가 짧으며 분지각도가 좁은 품종을 개발하여 분화용 및 분재용으로 개발하여 실내에서도 무궁화를 감상할 수 있도록 해야 할 것이다.

국내에서 유통되고 있는 오이 110 품종을 대상으로 microsatellite 마커를 이용하여 DNA profile 데이터베이스를 구축하기 위하여 품종식별력이 높은 분자 마커의 선정 및 이를 활용한 품종간 유전적 유사도 검정 등에 대한 연구를 수행하였다. 오이 11 품종을 358개의 microsatellite 마커로 검정하여 31개의 다형성이 높은 마커를 선정한 다음 110품종에 대한 DNA profile 데이터베이스를 구축하였다. 오이 110품종을 31개의 microsatellite 마커로 분석하였을 때 대립유전자의 수는 2-9개로 비교적 다양한 분포를 나타내었으며 전체 139개의 대립유전자가 분석되었다. PIC 값은 0.253-0.873 범위에 속하였으며 평균값은 0.610으로 나타났다. Microsatellite 마커들의 대립유전자를 이용하여 계통도를 작성하였을 때 110 품종이 과실의 형태에 따라 그룹화되는 것을 확인하였으며, 대부분이 품종이 microsatellite 마커의 유전자형에 의해 식별이 되는 것으로 나타났다. 이 연구결과에 의해 개발된 오이 품종별 DNA profile 데이터베이스는 품종보호 출원 품종의 선 DNA 검정을 통한 대조품종 선정, 구별성, 균일성, 안정성 확인에 매우 유용하게 이용할 수 있어 향후, 품종보호권 강화 등에 크게 기여할 수 있을 것으로 사료된다.
