This paper outlines the system and operation of plant variety protection right and plant patent of ornamental crops in USA to guide for application of new varieties developed in Korea and to use for national examination of applied variety from USA. The Plant Variety Protection Act(PVPA) in USA is given as PVPR to the developers of new variety for the seed propagating crops and tubers and provides as plant patent for asexually reproducing crops. A certificate of PVPR and plant patent is awarded to an owner of a variety has shown that it is new, distinct from other varieties, genetically uniform and stable through successive generations by official evaluation without the growing trial. The term of protection for plant patent and PVPR for most crops is 20 years but 25 years for trees, shrubs, and vines. The application of ornamental variety in USA is mostly for plant patent. The application of ornamental crops accounted for 87% of total applications for plant patent. The ratio of new variety applications for plant patent from national and foreign countries is not significant differences.

지난25년간 유전자변형 생물체(LMO)는 가장 성공적인 농업 기술의 하나로 자리잡았다. 그러나 동시에 LMO가 격렬한 찬반 논란의 중심에 있었고 이로 인한 엄격한 규제의 대상이 되어 왔다. 카르타헤나 바이오안전성의정서와 LMO 위해성 심사 및 승인 등은 이러한 엄격한 규제를 대표하는 국제 혹은 국가 수준의 정책사례라고 할 수 있다. 특히 유럽연합은 역내의 반-LMO 정서를 반영하여 스페인 등 일부 국가를 제외하고는 거의 모라토리움 수준의 LMO 규제를 실시하고 있다. 유럽식품안전청(EFSA)는 유럽연합의 이러한 정책 결정에 따라 역내의 LMO 재배 및 사용에 대해 엄격한 심사업무를 담당하고 있는 기관이다. 최근EFSA는 그 동안의 심사 경험을 바탕으로 LMO의 심사 경험과 LMO환경 방출에 대한 모니터링 결과를 공유하기 위한 자료를 발간했다. 이들 자료는 EU에 비견될 수 있을 정도로 LMO에 대해 부정적인 정책적 입장을 취하고 있는 우리에게 다양한 시사점을 제공할 것으로 판단된다. 본 발표에서는 최근의 LMO 정책 환경 변화를 돌아보고, EFSA 보고서의 시사점을 살펴봄으로써 우리의 LMO 규제 정책이 합리적으로 개선될 수 있는 방향을 제시하고자 했다.

수목의 품종을 연구하고 특성을 규명하기 위해 특성조사요령에 따라 특성 분석이 시행된다. 특성조사요령은 신품종 개발 및 품종 보호 출원을 위한 재배심사에 필요한 특성별 조사 방법을 규정하고 있다. 하지만 수목의 특성 분석 과정에서 연구자의 주관이 개입될 가능성이 있으며, 특성 분석의 신뢰성에 부정적인 영향을 미칠 수 있다. 본 연구에서는 딥러닝 모델을 활용하여 영상 속에서 수목을 검출하고, 특성조사요령에 규정된 특성들의 '표현 형태'를 출력하는 시스템을 구현함으로써 수목 특성 분석의 신뢰도를 높이고자 한다.

New Guinea impatiens (Impatiens hawkeri) shows very sensitive responses to different light conditions. Due to these phenomena, testers of DUS (distinctness, uniformity and stability) for granting plant variety protection right often have problems distinguishing genetic or physiological differences. New Guinea impatiens 'Fishlimp 149' was grown under several light intensities in a rain-sheltered vinyl house to observe differences of plant growth and flowering. As compared with the control (avg. $1,010{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$), treatments of shade-1 (avg. $599{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$) and shade-2 (avg. $88{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$) showed increased plant height, plant width, leaf size and pedicel length. On the contrary, these growth parameters decreased in shade-3 (avg. $30{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$) with the lowest light intensity. Shade-1 treatment enhanced flower characteristics such as flower diameter, upper petal width, side petal width and lower petal length. However, these characteristics were suppressed by lower light intensities than that in shade-1. Anthocyanin contents of shoot, leaf and pedicel decreased with increasing shading, but that of flower petal was the greatest of the shade-1 treatment. Shade-1 treatment showed the greatest Hunter a value analyzed by a colorimeter, and L and b values increased with increasing shading. Shade-1 treatment seemed to be provided the most proper light condition for DUS test of New Guinea impatiens. Additionally, anthocyanin accumulation on New Guinea impatiens during DUS test was due to not genetic differences but physiological phenomenon.

Since the implementation of the Living Modified Organisms (LMOs) Act in 2008, approximately 10 million tons of genetically modified corn, soybean, potato, canola, and other crops have been imported into South Korea. The import approval procedures have been completed for approximately 191 cases that include seven crops. Of these, approximately 90 cases, excluding crossbreeds of approved LMOs, were reviewed via consultation risk evaluation in four areas: human health, crop culture, natural ecology, and marine fishery environment. LMO developers in South Korea, who are major stakeholders in the import of LMO crops produced overseas, have raised concerns regarding procedural inefficiency in consultation reviews and the need of excessive reviews that are unsuitable for food-feed processing purposes. These procedures reflect the perspective of consultation agencies that deviate from the nature of risk assessment and demand specific supplementary data that do not reflect familiarity and substantial equilibrium. Based on frequent instances of unintentional environmental release of LMO crops imported into Korea, the ministries responsible for consultation insist on a review that considers the climate and natural environment of Korea. In addition, the ministries mandate that their reviews reflect the expertise of competent ministries and are based on risk assessment principles and methods in accordance with international guidelines. In this regard, considering that traits introduced into LMO crops involving familiar agricultural crops have been considered safe for more than two decades, we have suggested reasonable alternatives to several risk assessment items for agricultural LMOs. These alternatives can mitigate conflicts of interest among key stakeholders within the scope of the current LMO regulations.

Plant factories are plant cultivation systems which produce farm products uniformly under the controlled environmental condition regardless of seasons and places. Thermal flow in the plant factory is an important parameter in cultivating plants. In this research, we study thermal flow characteristics for a hybrid plant factory with multi-layer cultivation shelves using computer simulation techniques. In order to obtain numerical solutions for thermal flow characteristics, a finite volume method was applied. We consider a low-Reynolds-number ${\kappa}-{\epsilon}$ turbulence model, incompressible viscous flows, and pressure boundary conditions for numerical simulation. Commercial software Solid Works Flow Simulation is then used to investigate characteristics of thermal flows in the plant factory applying several different inflow air velocities and arrangements of cultivation shelves. From numerical analysis results, we found that temperatures in cultivation shelves were uniformly distributed for Case 3 when the inflow air velocity was 1.6 m/s by using a blower in the plant factory. However in Case 1 lower temperature distributions were observed in test beds, TB2 and TB3, which indicated that additional temperature control efforts would be required. Average shelf temperature increased by $3^{\circ}C$ using artificial light source (DYLED47) with 50% blue and 50% red LED ratios. Korea Academia-Industrial cooperation Society.

This study was conducted to examine the morphological characteristics of those Azalea Cultivars(hereinafter, Azalea Cultivars) that are mainly used for landscaping in Korea in order to prepare classification criteria. As testing materials, major Azalea Cultivars cultivated in large quantities by its producing companies were collected. Thereafter, the qualitative and quantitative characteristics of the traits of Azalea Cultivars were investigated in the way of characteristic investigation for new cultivars of azalea used by the Korea Seed and Variety Service in order to classify them and prepare the classification criteria. Since cultivar names have not been established for Azalea Cultivars for landscaping thus far, the data were compiled using the names used by cultivating companies. According to the results, Azalea Cultivars cultivated in Suncheon, Jeonnam mainly for landscaping were 10 in number; Beni, Daewang, Three, Zasanhong, Hancheol, Sancheoljuk, Gyeobsancheoljuk, Baekcheoljuk, Akado, and Seok-am. Among them, the cultivars Beni, Daewang, and Three could not be easily distinguished from each other because they are commonly called Yeongsanhong by cultivating companies and the shapes of their leaves and flowers are similar to each other. In particular, the flower color of Beni was 'bright red', that of Daewang was 'vivid purple', and that of Three was 'bright purple'. In addition, Zasanhong and Hancheol were similar to each other in shape the degree of expression of spots on the flowers and the gloss on the front side of the leaves of Hancheol were higher and stronger compared to that of Zasanhong. Sancheoljuk flowered in early April, earlier compared to other Azalea Cultivars. Gyeobsancheoljuk is an elementary species of Sancheoljuk and it had double flowers although all other traits were similar to those of Sancheoljuk. Although Baekcheoljuk was easily distinguished because it had white flowers, its leaves were similar to those of Akado the reason why these two cultivars could not be easily distinguished from each other. The cultivar Akado flowered early May later compared to other Azalea Cultivars and its flowers were relatively large in diameter as with Baekcheoljuk and Sancheoljuk. Finally, the cultivar Seok-am was easily distinguished because it had smaller leaves compared to other cultivars and it flowered late as with the cultivar Akado.

This study was carried out to construct a DNA profile database of 100 strawberry cultivars using microsatellite markers. Two hundred seventy four microsatellite primer pairs were screened with a set of 21 strawberry cultivars with different morphological traits. Twenty five primer pairs were selected because they produced reliable and reproducible fingerprints. These primer pairs were used to develop DNA profiles of 100 strawberry cultivars. Three to thirteen alleles were detected by each marker with an average of 7.50. The average polymorphism information content varied from 0.331 to 841 (average 0.706). Cluster analysis showed that the 100 cultivars were divided into 7 major groups reflecting geographic origin and pedigree information. Moreover, most of the cultivars could be discriminated by marker genotypes. These markers will be useful as a tool for the protection of plant breeders' intellectual property rights in addition to providing the means to intervene seed disputes relating to variety authentication.
