Abstract

A new poinsettia cultivar 'Clara' was bred by the National Institute of Horticultural and Herbal Science (NIHHS) in 2005. A cross was made between 'Red Velvet', a variety with dark green leaves and red bracts, and 'Freedom Bright Red', a variety with early short day responding and bright red bracts, in 2002. 'Clara' was finally selected in 2005 after the investigation of the growth and flowering characteristics from 2003 to 2005. 'Clara' has red ovate bracts and weak intensity of rugosity between bract veins. Leaf blade is ovate and medium green. Petiole length is relatively short, and stem color is reddish. 'Clara' has medium free-branching ability and makes short and compact canopy. Clara's bracts and transitional leaves are fully colored 9 weeks after short day commencement.

'Clara' 품종은 국립원예특작과학원에서 2005년도에 육성한 포인세티아 품종이다. 이 품종은 2002년에 진한 녹색 잎에 엽절이 있으며 선명한 적색인 'Red Velvet'을 모본으로, 단일반응이 빠르고 밝은 적색인 'Freedom Bright Red'를 부본으로 인공교배하여 양성된 실생계통 중 선발되었다. 2003년, 2004년 2차에 거쳐 특성검정을 하여 '원교 D5-12'를 육성하였고 2005년에 3차 특성검정과 품평회를 실시하여 최종선발 하였으며, 농작물 직무육성 신품종선정위원회를 거쳐 'Clara'로 명명하였다. 포엽의 형태는 난형이며 포엽의 엽맥 사이에 약한 주름이 있고 포엽의 색상은 적색이다. 잎몸은 난형이며 중간 녹색이고 엽절이 거의 없으며 엽병이 짧다. 줄기 색은 적색계이며 적심을 하지 않은 상태에서도 분지가 발생하고 줄기의 수는 중간이다. 초장은 작고 컴팩트한 수형을 이루며 단일처리 후 약 9주일이 경과하면 완전히 착색되어 출하가 가능하다.
