Abstract

A new cultivar Dendranthema grandiflourm 'Dream Round' was developed at Gyeonggi-do Agricultural Research & Extension Services (GARES), Korea in 2010. The variety 'Dream Round' was initially derived from a cross in 2006 between 'Hebo' a seed parent, a spray chrysanthemum cultivar with white anemone type, and 'Samos' as a pollen parent, a spray chrysanthemum variety with white anemone type. The cultivar has anemone type with white petals. Trial evaluation was conducted from 2008 to 2010 for the selection of that cultivar, including a shading culture in spring and a retarding culture in summer. The flowering time of 'Dream Round' was October 24th, and year-round flowering was possible by shading or lighting treatment. The diameter of flower of 'Dream Round' was 34.1 mm. Numbers of flowers per stem and petals per flower of 'Dream Round' were 12.8 and 26.1, respectively. Its leaf color was green (Green Group 147A) and plant height was 92.4 cm. Days to flowering of 'Dream Round' under the short day treatment was about 54 in spring, and diameter of flower of 'Dream Round' was 34.2 mm in the summer. The vase life of 'Dream Round' was 21.7 days in autumn.

'Dream Round'는 경기도농업기술원에서 2010년도에 육성한 절화용 스프레이 국화 신품종이다. 2006년도에 화색이 흰색이면서 갈색심을 가지는 아네모네형 스프레이용 국화 'Hebo' 품종을 모본으로 하고 분홍색의 아네모네형 스프레이용 국화 'Samos' 품종을 부본으로 하여 교배를 하였다. 2007년도에 실생을 양성한 후 선발된 실생계통 중에서 화색과 화형이 우수한 8계통의 예비선발을 수행하였으며, 2008-2010년에 주년 재배성을 위한 3회 이상의 특성검정과 품평회를 실시한 결과, 절화생육과 개화특성이 우수한 'GCS 06-'99-10' 계통을 최종 선발하여 'Dream Round'로 명명하였다. 'Dream Round'는 흰색의 설상화(RHS White Group 155B)에 진분홍색(RHS Red Purple Group 68A)의 통상화를 가지는 아네모네형으로 꽃잎수는 26.1매이고, 꽃직경은 34.1mm 이며, 절화장은 92.4cm이고 흰녹병 발생은 거의 없었으며, 절화 수명은 21.7일 이었다.
