Breeding of Phalaenopsis ‘SM 3337’ with Stripe Type of Pink Flower

A new Phalaenopsis cultivar SM 3337 was bred by Sangmiwon, Korea. The new cultivar SM 3337, with a pink color and striped characteristics, was derived by artificial crossing between Phal. Minho Princess (the female parent) and Phal. Minho Stripes (the male parent). From 2006 to 2007, 300 individuals were cultivated over 2 years. Among them, an elite individual, number ‘05-33-37’, with excellent growth and flowering characteristics was finally selected through an intensive selection process. The stability and uniformity of the cultivar were confirmed through the first and second characteristics tests in 2008 and 2009, and it was named ‘SM 3337’. SM 3337 produces bright clean pink (RHS#69C) flowers with incurved shape and striped characteristics, with a flower length and width of 9.8 cm and 10.8 cm, respectively. SM 3337 is regarded as a lightly striped flower type and is suitable for the new flowerpot market. The leaves of SM 3337 are arranged horizontally and are 22.2 cm in length and 10.7 cm in width. This cultivar also possesses no genetic variation, fast in vitro propagation, and easy growing due to vigorous growth habit. SM 3337 was registered to Korea Seed & Variety Service (KSVS) in September 30, 2013 and the plant breeder’s right (PBR) is currently controlled by Sangmiwon Orchid Company, Korea (Registration No. 4640).
