농촌진흥청 국립원예특작과학원에서는 2018년 오리엔탈-트럼펫(OT) 종간잡종나리 ‘Pink Bella’를 개발하였다. 2008년 연노란색 OT 종간잡종나리 ‘Valparadiso’와 붉은색의 오리엔탈나리 ‘Scalini’를 각각 모본과 부본으로 화주 절단 수분법과 주 두교배법으로 각 3화를 인공교배하였고, 교배 후 미숙한 3개의 꼬투리를 수확하여 배가 형성된 배주를 기내에서 배양하여 잡종을 획득한 후 재배하였다. 육묘한 배양묘로부터 2011년 분홍색의 OT 종간잡종 나리 ‘OTO-11-43’ 계통을 개체 선발하였다. 2012년부터 2017년까지 선발된 계통은 자구와 인편번식, 조직배양을 이용하여 번식 및 양구한 후 1, 2차 생육특성 검정을 실시하였다. 2018년 3차 생육특성검정 및 소비자 기호도 평가를 수행한 결과 화색 및 화형에 대한 기호도가 높은 분홍색(RHS, RP62C)의 조기개화성 절화용 OT 종간잡종 나리 ‘Pink Bella’를 육성하였다. 3배체의 OT 종간잡종 나리로 초장은 131.7cm로 초장신장성이 우수하였다. ‘Pink Bella’의 화폭은 18.6cm이며 대조품종 ‘Table Dance’의 18.4cm와 유사한 크기였으며, 내화피의 폭, 길이 역시 대조품종과 통계적인 차이가 없었다. ‘Pink Bella’의 개화기는 6월 15일로 대조품종 ‘Table Dance’의 6월 28일에 비교하여 개화기가 13일 단축된 것으로 나타났으며 통계적으로 유의하였다.

NDF (No Defect Found) is a phenomenon in which defects have been found in the manufacturing, operation and use of a product or facility, but phenomenon of defects is not reproduced in the subsequent investigation system or the cause of the defects cannot be identified. Recently, with the development of the fourth industrial revolution, convergence of hardware and software technologies in various fields is spreading to products such as aircraft, home appliances, and mobile devices, and the number of parts is increasing due to functional convergence. The application of such convergence technologies and the increase in the number of parts are major factors that lead to an increase in NDF phenomena. NDF phenomena have a significant negative impact on cost, reliability, and reliability for both manufacturers, service providers and operators. On the other hand, due to the nature of NDF phenomena such as difficult and intermittent cause identification and ambiguity in judgment, it is common to underestimate the cost of NDF or fail to take appropriate countermeasures in corporate management. Therefore, in this paper, we propose a methodology for estimating NDF costs by the PAF model which is a quality cost analysis model and ABC (Activity Based Costing) technique. The methodology of this study suggests a detailed procedure and the concept to accurately estimate the NDF costs, using ABC analysis, accounting system information, and IT system data. In addition case studies have validated the methodology. We think this could be a valid methodology to refer to when estimating the cost of other parts. And, it is meaningful to provide important judgment information in the decision-making process based on quality management and ultimately reduce NDF costs by visualizing them separately by major variable factors.

Rose is one of the most economically important ornamental crops worldwide. Although rose products are widely used, limited genetic and genomic data from this species is available. Fundamental genetic knowledge can accelerate the development of superior rose germplasms. In the present study, we explored the genetic data (e.g., chromosome numbers, total chromosome length, and ploidy level) of 39 rose cultivars using conventional cytogenetic methods. Of the 39 rose cultivars tested, 36 (92.3%) were tetraploid (2n = 4x = 28). ‘Rosada,’ ‘Rosemarin,’ and ‘Hanmaum’ were diploid (2n = 2x = 14), triploid (2n = 3x =21), and tetraploid-based aneuploid (2n = 4x = 28 + 2), respectively. The total chromosome length ranged from 46.03 ± 0.55 μm in ‘Rosada’ (2x) to 138.51 ± 0.92 μm in ‘Christoper’ (4x). The chromosome information obtained in this study will be useful for rose breeding and germplasm evaluation.

Currently, the cut flower market seems to be an export revenue in the world trade of the flower industry. The amount of exported cut flowers is impressive with increased production in various countries, especially in Korea. In the Fourth Industrial Revolution, automatic technologies are continuing to develop agricultural effective tools in the challenge of digital innovation. Thus, the low production costs set up in the field, greenhouse, or smart farm set up, and the short time of harvest must be considered within a few months. The postharvest quality of cut flowers presents freshness and long vase life, and the tools for postharvest handling are expected to optimize these. This review highlights the most important factors improving postharvest quality of cut flowers, the potential standard applicable techniques for commercial handling outlines of cut flower vase life, and recommendations for improving postharvest handling in the flower industry.
