Abstract

'Secret Pink' was released by National Institute of Horticultural & Herbal Science in 2008. The cross was made between '03B1-23' and 'Sei-Monaco in 2005'. After the evaluation of the characteristics under shade culture in summer and retarding culture in spring and consecutive selection from 2006 to 2008, 'Secret Pink' was selected finality. The natural flowering time of 'Secret Pink' was the middle of October, and it is possible to flower all year round by shade and light culture. It has single type flowers with pink petals. The growth of plant was very vigorous and response time was 6.5 weeks. The diameter of flower was 6.7 cm. Number of flowers per stem and petals per flower were 14.5 and 25, respectively. Days to flowering under the short day treatment was about 50 and its vase life was 25.5 days in autumn season.

국화 '시크릿핑크'는 농촌진흥청 원예특작과학원에서 2005년에 분홍 홑꽃의 육성계통인 '03B1-23'에 중생 하추국인 'Sei-Monaco'를 교배하여 획득한 실생 집단으로부터 조생다화성 분홍 홑꽃인 '05B1-49' 계통을 선발하여 3년간 특성 검정으로 통해 2008년에 '시크릿핑크'를 육성하였다. '시크릿핑크'는 10월 중순에 자연 개화하는 절화용 스프레이 추국이다. 분홍색의 녹색화심을 지닌 홑꽃 중형화로 개화소요 일수가 50일, 6.5주 개화반응을 보이는 조생성이다. 본 육성 품종은 다화성이며, 절화수명이 26일 정도로 길고 착화성이 우수하다. 특히 여름철 화색발현이 뛰어나며 연중 생육속도가 일정하여 촉성 및 억제재배 등 주년재배 품종으로서 적당하다. 초장은 110cm 이상, 꽃의 직경은 6cm 이상, 꽃잎수는 소화당 25매 정도, 착화수는 본당 15화 내외이다. 재배상 유의점으로는 여름 장마철 또는 겨울철 환기가 불량 할 경우 흰녹병 발생에 주의하고 주기적인 방제가 필요하다.
