A new spray chrysanthemum (Dendranthema grandiflorum) cultivar, 'Dimple' was developed from a cross between 'champy' and 'SP05-135', by selection of seedlings and lines at the Flower Research Institute, Gyeongnam Agricultural Research and Extension Services (ARES) from 2005 to 2009. Its characteristics were investigated three times from 2007 to 2009 under condition of forcing culture in spring and retarding culture in autumn. The natural flowering time of 'Dimple' was October 24th, and year-round production was possible by day-length control. This cultivar has single type flowers with bright yellow ray floret and green center. The plant is very vigorous and very stable in the color of petals when it is cultivated even under high temperature condition in summer. Its flower was 4.7 cm in diameter, and it had 20.3 flowers per stem in autumn. The days to flowering under the short day treatment is about 50 in spring season, and 'Dimple' showed the vase life of 21.3 days in autumn. This cultivar was registered for the protection in 2009.

잇꽃(Carthamus tinctorius L.)은 국화과에 속하는 두해살이 초본 식물로 한자명은 홍화(紅花), 영명으로는 Safflower를 사용하고 있다. 잇꽃의 원산지는 이집트, 아프카니스탄 등의 서남아시아가 원산지로 알려져 있으며, 우리나라의 잇꽃 재배면적은 2010년 39 ha 수준이 재배되다가 2016년에는 67 ha로 재배면적이 증가한 것으로 보고되고 있다. 우리나라에서 잇꽃 이용은 잇꽃 종실을 위주로 이용되고 있으나 일본의 경우 잇꽃의 경관적 가치를 활용하여 산형현(山形縣)에서는 홍화축제가 매년 개최되고 있으며, 미국 등에서는 잇꽃의 저온압착유가 기능성 건강식품류로 판매되고 있다. 본 연구는 일조시수가 짧은 표고 500 m의 준고랭지에서 잇꽃의 경관적 가치 활용도를 평가하기 위해 차광조건에 따른 개화특성 및 종실 수량성을 평가하기 위해 수행되었다. 비가림 하우스에서 5월 9일 파종후 생육 54일차인 7월 5일 개화기에 지상부 발육량을 조사한 결과 차괄비율이 강해질수록 엽장폭비가 감소하여 세장형에서 장타원형으로 성장함을 알수 있었고, 분지수는 30% 차광조건에서 증가하는 경향을 보였다. 같은 시기에 조사한 엽면적에서는 30% 차광에서 증가하다가 차광비율이 높아질수록 감소하였으며, 식물체당 총 착화수는 30% 차광조건에서 20.3화/주로 가장 많았고 2차 화경의 착화수도 많은 경향을 보였다. 착생된 꽃의 개화단계를 3등급으로 구분하여 비율을 조사한 결과 차광 조건에서는 개화 2, 3단계의 비율이 무차광에 비해 낮아 개화가 지연됨을 알수 있었고, 건조한 관상화의 색도에서는 차광비율이 높아질수록 b 값이 증가하여 황색값이 높아지는 것을 알수 있었다. 파종 후 생육 94일 차인 8월 13일 종실을 수확하여 식물체당 100립중을 조사한 결과 무차광 4.9 g에 비해 차광조건에서는 감소하는 경향을 보였고, 종실수량성에서도 무차광에서 201.1 kg/10 a로 가장 높아 차광조건에서 잇꽃 재배는 개화지연에 의한 등숙률의 감소로 종실수량성이 감소하는 것으로 판단되었다.

Cymbidium 'Purple Star' (Miake 'Pieta' ${\times}$ 'Allstar Mariane') was developed from a cross between hybrids at the National Institute of Horticultural & Herbal Science (NIHHS), Rural Development Administration (RDA) in 2008. A cross was made between purple colored flower C. Miake 'Pieta' as maternal line and dark pink colored flower, C. 'Allstar Mariane' as paternal line in 1995. The seed germination, cultivation, selection, and characteristic trials were conducted from 1996 to 2002. The line was named as Wongyo 'F1-21' and phenotype was characterized in 2007 as a new cultivar. The 'Purple Star' has dark purple basal color (RHS, GP186A) on both of sepal and petal with red lip (RHS, RP59A). 'Purple Star' has about 10.7 flowers per flower stalk and flower size of 7.6 cm. General appearance of petals and sepals is slightly incurved shape. The plant size is intermediate having erect peduncle. Blooming is started from the late of January (mid-winter) under optimal culture condition. Leaf attitude and twisting is erect and weak respectively. This hybrid has attractive floral arrangement, long flower stalk (78.4 cm) and vigorous growth. 'Purple Star' has a great potential for exporting to Chinese market.

A FA (Lilium formolongi $\times$ Lilium asiatic hybrid) intersectional hybrid lily cultivar 'Orange Crown' was developed in 2007 at National Institute of Horticultural and Herbal Science (NIHHS), Rural Development Administration (RDA) of Korea. The cross and immature embryo rescue was conducted between female parents 'Migreen' (Lilium formolongi 'Raizan' $\times$ Lilium asiatic hybrid 'A61') and male parent 'A01-187' (L. asiatic 'A96-28' $\times$ 'Sanzio') by cut style pollination method at Suwon in 2001. It was preliminarily selected as 'FA04-27' in 2004. Multiplication, bulb production and characteristic tests were conducted from 2004 to 2007. The evaluation of characteristics and preference were surveyed at a lily flower show of NIHHS at Taean in 2007. 'Orange Crown' flowers in the late of June and grows more than 183 cm stem length. Flowers bloom upward-facing, a little spotted and orange (RHS, O24A) petals. The pollen of 'Orange Crown' was sterile.

'Anyu', a perilla (Perilla frutescens (L.) Britton) cultivar for edible seed was developed by the Department of Functional Crop Science, National Institute of Crop Science, RDA in 2008. It was originated from the cross between a pedigree of YCPL1824 as a female and SF9225-3-1 as a male parent in 1998. 'Anyu' can be characterized by purple flower color and brown grain color. 'Anyu' showed semi-dwarft type with 120 cm height, and has lodging tolerance. Maturing date of 'Anyu' was September 24, which is 15 days faster than that of 'Saeyeopsil'. The early maturity of this new cultivar showed a great advantage to various planting system with other crops. This new cultivar has high oil content (45%) and high linolenic acid in the fatty acid composition. The yield potential of 'Anyu' was about 0.9 ton/1ha in the regional yield trial.

A FA intersectional hybrid lily cultivar 'Golden Center' was developed in 2008 at National Institute of Horticultural and Herbal Science (NIHHS), Rural Development Administration (RDA) Korea. The cross was conducted between female parent Lilium FA hybrid 'Migreen (FA97-30)' and male parent L. Asiatic hybrid 'Sanzio' by a cut style pollination method (CSM) and immature embryo rescure at Suwon in 1999. The first selection was done and the line name was tentatively given as 'FA04-24' in 2004. After in vitro multiplication, bulb-producing ability, line, growth and flowering characteristic of 'FA04-24' were evaluated from 2005 to 2007. The evaluation of characteristics and consumer preferences were surveyed at a lily flower show of NIHHS in 2008. 'Golden Center' flowers in the middle of June and grows up to 144 cm high in length. Flower blooms facing upward, with light yellow petals (RHS, GW157C). The pollen of 'Golden Center' is sterile. Year-round flowering can be done by storing the bulb under $-1.5^{\circ}C$ conditions. It is needed to control Botrytis disease in wet season.
