A new pink gerbera (Gerbera hybrida Hort.) cultivar “Pink Giant” was developed from a cross between “Salina” and “Marita” followed by seedling and line selections at the Flower Breeding Research Institute, Gyeongnam Agricultural Research and Extention Services (ARES) in 1999. Characteristic trials were conducted three times from 2002 to 2004. Newly bred “Pink Giant” have shown pink color (RHS, 65-B), semi-double type, and large flower. It also was in good harmony in ray floret color and flower center color with stable flower shape. The vase life was 19.2 days. The average yield of “Pink Giant” was 45.8 flowers per plant in an year in greenhouse yield trails during 2003 and 2004. This cultivar was registered for a commercialization in 2005. “Pink Giant” would be cultured under greenhouse condition in Korea.
