A new spray chrysanthemum cultivar, 'Moon Festival' was released by National Horticultural Research Institute (NHRI), Rural Development Administration (RDA), Korea in 2007. A cross was made in 2002 between '01B1-559', a breeding line of NHRI and 'Baeksokuk', a spray cultivar with white petals. Trials were conducted from 2005 to 2007 for evaluation and selection of this cultivar, including shading culture in summer and retarding culture in autumn. The natural flowering time of "Moon Festival" is late October, but year-round flowering is possible by shading and lighting treatment. The cultivar is semi- double type flowers with light-ivory white petals and green flower center. Flower neck and stem are very hardy. The diameter of flower is 67.5 mm. The number of flowers per stem and petals per flower is 11.5 and 100.5, respectively. The days to flowering under the short day is about 54 in autumn season.

In this study, we tried to offer the possibility of White Hibiscus syriacus L. (WHS) flower extracts as a preventive and improving agent of osteoporosis that bone mass reduction is induced by an decrease of osteoblast involved in bone formation and increase of bone resorption by osteoclast activity. As a results, it was found to have antioxidant activity and contain a flavonoid contents ($47.74 mg/g) of the WHS flower. There was cytotoxicity at more than $250{\mu}g/m{\ell}$ concentration of WHS flower extract of RANKL-induced osteoclast in RAW264.7. There were no significant inhibited TRAP activity in the WHS leaf and stem. However, it was confirmed that it is significantly inhibited the differentiation activity of osteoclasts in 50 and $100{\mu}g/m{\ell}$ concentration of cells of stability levels of only WHS flower extracts (p < 0.01). The WHS flower prominently inhibited RANKL-induced osteoclast differentiation activity by decreased calcitonin receptor and TRAP mRNA (p < 0.01). These results indicate that of osteoclasts differentiation activity is inhibited by protection of oxidative stress due to the antioxidant activity of the WHS flower. Therefore, suggesting the WHS flower may be a presents the possibility as a preventive and therapeutic agents for osteoporosis.

This study was conducted to analyze the morphological characteristics such as flower color, flower type, flower diameter and flower stalk, and the main annual production yield, and genetic similarity of twenty four Gerbera species growing in Korea. Most of flower colors were pink. The numerical order of flower color was pink, orange, red, double-colored, and milk-white. Majority of flower types were sin81e or semidouble flowers. A few species were double flowers. flower diameters were from 7 ㎝ to 12 ㎝, showed significant differences compared to other characteristics. Flower stalks were ranged from 55 ㎝ to 65 ㎝. Only one species was the shortest as 55 ㎝. The others were similar size as about 65 ㎝. Main annual production yields were between 190 and 400 blossoms. Fifty seven reproducible polymorphic bands from eighty primers were used for analyses of genetic similarity. The genetic similarity of 24 collected Gerberas was largely classified into five groups. The average similarity coefficient was 0.72 ranged from 0.50 to 0.90. The highest similarity coefficient was shown between 'Sardana' with red/white flower color and double flower type, and 'Tamara' with orange flower color and double flower type as 0.90.

무안 회산지 백련꽃의 재배와 개화 조절에 필요한 자료를 얻기 위하여 2008년 4월 20일과 5월 4일에 각각 비대근경과 종자를 용기에 식재하여 비가림 재배 관리한 후 동년 9월 4일에 근경생장 유형과 개화 특성을 조사하였다. 주근경이 분지된 것은 실생의 경우 10%, 비대근경은 15%였다. 주근경의 마디 수는 개화된 것은 14개 이상이었으며, 개화가 되지 않은 것은 11마디 이하였다. 실생 번식한 것은 모두 개화되지 않았으며, 비대근경을 식재한 것은 80%가 개화되었다. 첫 번째 꽃은 7월 말과 8월 초에 피었으며, 4.0~4.4개의 꽃이 피었다. 첫 번째 꽃대는 주근경이 분지되지 않은 것의 경우 8.8번째 마디에서, 주근경이 분지된 것은 8.0번째 마디에서 출현되었다. 화경이 지상부에 출현된 후 개화까지는 16일이 소요되었다. 백색의 꽃은 높이 15.3 cm, 폭 28.2 cm 크기로 수명은 3.3일이었으며, 생체중은 29.2 g이었다. 이상의 결과로부터 무안 백련꽃의 개화를 시키기 위해서는 근경의 비대가 시작되기 이전에 주 근경의 마디를 8마디 이상 생장시켜야 함을 알 수 있었다.

경남농업기술원 화훼육종연구소에서 2000년부터 교배조합 육성을 위하여 국내의 재배농가와 종묘업체로부터 유전자원을 수집한 후, 2000년부터 2007년에 걸쳐 교배 및 계통선발육종을 하였다. 2004년부터 2006년까지 3회의 특성검정을 거쳐서 호접란 신품종 '리틀 듀'를 개발하였다. '리틀 듀'는 백색 미니 다화성계 품종으로 꽃잎, 꽃받침, 설판이 모두 백색이며 꽃 크기는 3~4cm 정도이다. 특히 화경이 3~4개 정도가 발생하여 많은 꽃이 피고 꽃배열도 우수하여 관상가치가 높아 시장성이 우수하다고 판단되었다. 또한 조직배양을 통해 영양번식도 용이한 것으로 나타났고 재배가 용이하고 생육속도도 매우 빠른 것으로 나타났다. 꽃수명도 긴 편이며 병충해 발생도 적고 저온처리를 통한 개화조절도 용이하여 상업용 재배에 적합한 품종으로 판단되었다.
