Abstract

A new poinsettia cultivar 'Heidi' was bred by the National Institute of Horticultural and Herbal Science (NIHHS) in 2004. A cross was made between 'Freedom Rose', a variety with vigorously growing deep pink color, and 'Red Velvet', a variety with dark green leaves and red bracts in 2001. 'Heidi' was finally selected in 2004 after the investigation of the growth and flower characteristics from 2002 to 2004. It has velvety red colored elliptic bracts and transitional leaves, and medium intensity of rugosity between bract veins. Leaf blade is dark green, ovate shape and lobes are shallow. Petiole length is relatively short and stem color is reddish. 'Heidi' has free-branching ability and plant height is short. The bracts and transitional leaves are fully colored 7.5 weeks after short day commencement.

'Heidi' 품종은 국립원예특작과학원에서 2004년도에 육성한 포인세티아 품종이다. 이 품종은 2001년에 생육이 왕성하고 진분홍색인 'Freedom Rose'를 모본으로, 진한 녹색 잎에 결각이 있으며 적색인 'Red Velvet'을 부본으로 교배를 실시하여 양성된 실생계통 중 선발되었다. 2002년과 2003년 2차에 거쳐 특성검정을 하여 '원교 D5-9'를 육성하였고, 2004년에 3차 특성검정과 품평회를 실시하여 최종선발, 'Heidi'로 명명하였다. 포엽의 형태는 타원형이며 포엽에 접힘이 있고 포엽엽맥사이에 중간 정도의 주름이 있으며 포엽의 색상은 벨벳질감의 적색이다. 잎몸은 난형이며 진한 녹색이고 결각이 거의 없으며 엽병이 짧다. 줄기 색은 적색계이며 적심을 하지않은 상태에서도 분지가 발생하나 줄기의 수는 적다. 초장은 작으며 단일처리 후 약 7.5주일이 경과하면 완전히 착색되어 출하가 가능하다.
