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.
