Abstract

A spray chrysanthemum cultivar 'Green Candy' was released by National Institute of Horticultural & Herbal Science, Rural Development Administration, in 2009. The cross between 'Yoko Ono', a spray chrysanthemum cultivar with light yellowish-green double type, and 'Green Bird', a spray chrysanthemum cultivar with vigorous and green double type, was made in Suwon in 2006. After the evaluation of the characteristics under shade culture in summer and retarding culture in spring and consecutive selection from 2007 to 2009, 'Green Candy' was selected finality. The natural flowering time of 'Green Candy' is October 28th, and it is possible to flower all year-round by shade and light culture. It has double flower type with green petals. The growth of plant is very vigorous and the color of the petals is stable when the variety is cultivated under high temperature conditions in summer season. The diameter of flower is 4.1 cm. The numbers of flower per stem and petals per flower are 12 and 217, respectively. The days for flowering under the short day treatment are about 58 and its vase life is 18.1 days in autumn season. 'Green Candy' was applied as No. 2010-212 on March 5, 2010 for variety protection and the plant variety protection rights have been registered as No. 3633 on August 2, 2011 at the Korea Seed and Variety Service.

국화 'Green Candy'는 농촌진흥청 원예특작과학원에서 2006년에 녹색 겹꽃인 'Yoko Ono'에 녹색 겹꽃인 'Green Bird'를 교배하여 획득한 실생 집단으로부터 녹색 폼폰 화형의 겹꽃 '06B1-161' 계통을 선발하였다. 선발계통을 2007년부터 2009년까지 3년간 특성검정을 통해 2009년에 'Greeen Candy'를 육성하였다. 국화 'Greeen Candy'는 10월 하순에 자연 개화하는 절화용 스프레이 추국이다. 녹색화심, 녹색의 겹꽃 중형화로서 개화소요일수가 58일인 7.5주 개화반응을 보이는 중생종이다. 본 육성품종은 여름철 고온기에도 통상화가 발생하지 않고 화색이 우수하게 발현되며, 촉성 및 억제 재배 등 주년생산이 가능하다. 본 육성품종의 초장은 100cm 이상, 꽃의 직경이 4.1cm 내외, 꽃잎수는 소화당 210매 이상, 착화수는 본당 12화 내외로 절화수명은 18일 정도이다. 본 육성품종의 재배상 유의점으로는 여름 장마철 또는 겨울철 환기가 불량할 경우 흰녹병 발생을 주의하고 주기적인 방제와 채화 후 각각의 절화가 뒤엉키지 않게 하여 꽃목 꺾이는 것을 방지하기 위한 노력이 필요하다.
