Abstract

신품종 Phalaenopsis 'SM 333'은 2002년 상미원에서 Phalaenopsis 'Odoriko'와 Phalaenopsis 'Be Tris'를 모부본으로 인공교배하여 육성한 <TEX>$F_1$</TEX> 개체 중에서 선발한 핑크 소형 다화 분지성이다. 2003년부터 2004년까지 2년에 걸쳐 실생 300개체를 양성하여 이들 중에서 영양생장과 개화특성이 우수한 개체 02-03-33을 선발하였다. 2004년과 2005년에 1차, 2차 특성검정을 통하여 품종의 안정성과 균일성을 확인하고 'SM 333'으로 명명하였다. 'SM 333'은 화색이 화사하고 선명한 핑크(RP69D)이며, 화형은 앉아피기로 안정되어 있다. 꽃의 길이와 폭은 각각 5.0, 5.8cm로 소형이다. 복총상화서로 볼륨이 있으며 소형 캐주얼분화에 적합하다. 잎의 길이와 폭은 각각 20.8, 6.5cm이며 엽형은 수평이다. 기내증식율이 높고 변이가 거의 없으며 영양생장 우수하여 재배관리가 용이하다. 2009년 12월 1일 품종등록(등록번호 제2916호)하여 종자산업법에 의해 보호받고 있다. A new Phalaenopsis cultivar 'SM 333' was bred by Sangmiwon Orchid, Korea, which produces young plants through tissue culture techniques. The new cultivar 'SM 333', showing the phenotype of multiflora with pink color and small, multibranching-type characteristics, was derived from crossing between Phalaenopsis 'Odoriko' and 'Be Tris'. An elite individual number '02-03-33' later termed 'SM 333' was selected among about 300 individual progenies, based on an intensive selection process covering vegetative and flowering distinctiveness over more than 2 years. In year 2004-2005, the 1st and 2nd characteristic analyses were carried out through performance and uniformity tests. 'SM 333' shows flower color that is bright clean pink (RHS # RP69D) and flower shape that is formal type with 5.0 and 5.8 cm in flower height and width, respectively. 'SM 333' is regarded as raceme flower type suitable for the small casual flower market. The leaves of 'SM 333' grow horizontally and about 20.8 cm in length and 6.5 cm in width. This cultivar also possesses no genetic variation, and is amenable to fast in vitro propagation and easy growth due to its vigorous growth habit. This 'SM333' was registered (Reg. # 2916) with Korea Seed & Variety Service (KSVS) on 1st December, 2009, and the plant breeder's right is currently controlled by Sangmiwon Orchid Company, Korea.
