Abstract

A new rose cultivar was bred by crossing the red-yellow standard cultivar 'Konfetti' and pink standard cultivar 'Laser' at the Chungcheongbuk-do Agriculture Research and Extension Services. The cross was completed in 2003, after varietal characteristics was tested for 3 years from 2005 to 2007, 'Suryeo' was finally selected in 2007 and registered on the grant of plant variety rights in 2009. The cultivar was developed for a standard-type cut flower with white-pink petals. 'Suryeo' produced 149 stems/$m^2$ in a year and had 64 petals per flower. This new cultivar needed 48 days to flower and showed 12 days vase life. The length of cut stem was about 78 cm, and the fresh weight of stem was 50 g. This cultivar showed high resistance against powdery mildew.

충북농업기술원에서 육성한 장미 '수려'는 절화용 장미로 황적색 스탠다드 계통의 장미 품종인 'Konfetti' 품종을 모친으로, 분홍색의 화색을 가진 스탠다드 계통의 'Laser' 품종을 화분친으로 하여 2003년에 인공 교배한 후 계통선발 및 3차 특성 검정을 거쳐 2007년에 최종 선발하여 '수려(Suryeo)'로 명명하였으며 2009년에 품종보호권이 등록되었다. 수려는 백색과 분홍색(Red-purple Group N57B)이 혼합된 스탠다드형 장미로 연간 절화수량은 149(본/$m^2$/년)이고 꽃잎수는 64매, 개화소요일수는 48일, 절화수명은 12일 정도이다. 절화장은 78cm이며 꽃무게는 50g이었다. 특히 수세가 강건하며 흰가루병에 강한 특성이 있다.
