Abstract

A new poinsettia(Euphorbia pulcherrima. Willd. ex Klotzch) cultivar 'Red Stone' was bred by the National Institute of Horticultural and Herbal Science (NIHHS) in 2009. In 2006, a cross was made between 'Freedom Rose', a cultivar with vigorous growth and deep pink bracts, and 'Enduring Pink', a cultivar with pink bracts early colored. 'Red Stone' was finally selected in 2009 after the investigation of the growth and flowering characteristics from 2007 to 2009. 'Red Stone' has red elliptic bracts and strong rugosities between bract veins. Leaf blade is ovate and very dark green. Stem color is reddish and petiole length is medium but relatively longer than that of 'Pepride Red', control cultivar. 'Red Stone' develops as many as 3.8 branches and which is more than double of 'Pepride Red'. Its bracts and transitional leaves are fully colored at 7.5 weeks after short-day commencement. Plant variety protection right of 'Red Stone' was registered in April 2011, and its grant number is 3487.

포인세티아(Euphorbia pulcherrima. Willd. ex Klotzch) 'Red Stone' 품종은 국립원예특작과학원에서 2009년도에 육성한 품종이다. 이 품종은 2006년에 생육이 왕성하고 진한 분홍색의 'Freedom Rose'를 모본으로, 착색이 빠르고 분홍색인 'Enduring Pink'를 부본으로 인공교배하여 양성된 실생계통 중에서 선발되었다. 2007~2008년 2차에 거쳐 특성검정을하여 '원교 D5-65'를 육성하였고 2009년에 3차 특성검정과 품평회를 실시하여 최종선발 하였으며, 농작물 직무육성 신품종선정위원회를 거쳐 '레드 스톤(Red Stone)'으로 명명하였다. 포엽의 형태는 도란형이며 포엽의 엽맥 사이에 강한 주름이 있고 포엽의 색상은 적색이다. 잎몸은 난형이며 진한 녹색이고 엽절의 수와 깊이는 중간이다. 줄기 색은 적색계이며 적심을 하지 않은 상태에서도 분지가 왕성하게 발생하고 줄기의 수는 많다. 초장은 작으며 단일처리 후 약 7.5주일이 경과하면 완전히 착색되어 출하가 가능하다.
