Abstract

A new spray chrysanthemum cultivar 'Yellow Candy' was released by National Institute of Horticultural & Herbal Science (NIHHS), Rural Development Administration (RDA), in 2008. The cross was made in 2003 between 'Restone' and 'Lollipop'. Trials were conducted from 2006 to 2008 for the evaluation and selection of this cultivar, including shading cultures in summer and retarding cultures in spring. The natural flowering time of 'Yellow Candy' is late October, but year-round flowering is possible by photoperiodic control. It has pompon flower type with yellow petals and yellowish red flower center. The growth of plant is very vigorous. The diameter of flower is 4.3 cm. Number of flowers per stem and petals per flower are 8 and 184, respectively. Days to flowering under the short day treatment is about 58.5 and its vase life is 18.5 days in autumn season. 'Yellow Candy' was applied as No. 2009-177 on Feb. 18, 2009 for variety protection and the plant variety protection rights have been registered as No. 3247 on August 3, 2010 at the Korea Seed and Variety Service.

농촌진흥청 원예특작과학원에서는 2003년에 황색 폼폰 화형인 'Restone'에 자주색 폼폰 화형인 'Lollipop'을 교배하여 획득한 실생 집단으로부터 황색 적심 폼폰 화형의 겹꽃 '03B1-82' 계통을 선발하였다. '03B1-82' 계통은 2005년 겨울부터 2007년 3년에 걸쳐 1, 2차 특성검정을 통해 안정성, 균일성 및 흰녹병저항성 검정 및 절화수명에 대해 조사되었고, 2008년에는 우수선발계통으로 '원교B1-142호' 계통번호를 부여받아 3차 특성검정을 실시하여 안정성, 균일성에 대한 연차별 재현성 그리고 주년생산성(촉성, 억제재배), 생산자 및 소비자 기호성을 평가 받았다. '원교B1-142호'는 2008년에 직무육성품종심의회를 거쳐 '옐로우캔디'로 명명되어졌다. 국화 '옐로우캔디'는 10월 하순에서 11월 상순에 자연 개화하는 절화용 스프레이 추국이다. 황색의 적색화심을 지닌 폼폰화형의 겹꽃으로 초세 및 줄기가 강건하다. 특히 여름철 고온기에도 통상화가 많이 발생하지 않으며, 촉성 및 억제재배 등 주년생산이 가능하다. 꽃의 직경이 4.3 cm 내외, 꽃잎수는 소화당 180매 이상, 착화수는 본당 8화 내외의 중형화로 절화수명은 18일 정도이다. 재배상 유의점으로는 둥근모양의 폼폰형이기 때문에 수확시 꽃이 서로 엉키면 꽃이 떨어지는 경우가 있으며, 여름 장마철 또는 겨울철 환기 부족시 흰녹병 발생을 주의하고 주기적인 방제가 필요하다.
