Origin & Breeding History: 'Suntutuki' originated from a controlled cross between two proprietary lines, made at the Omi Research & Development Center of Suntory Flowers Ltd., Shiga, Japan. The cross was made in July 2000 and in January 2001, the seed was sown in a greenhouse for evaluation. In August 2001, the new variety was selected as a single seedling based on its plant growth habit, flower size, flower colour and time of flowering. In November 2001, the new variety was propagated by cuttings in Shiga-ken, Japan and tested further in greenhouse and field trials from November 2001 to October 2002.
Tests & Trials: Trials for 'Suntutuki' were conducted in a polyhouse during the spring of 2005 at BioFlora Inc. in St. Thomas, Ontario. The trial included 15 plants of each variety. Rooted cuttings were transplanted into 15 cm pots on May 9, 2005. Measured characteristics were based on measurements taken from 10 plants or parts of plants. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
