Origin & Breeding History: 'Sunbelsuka' was developed from a cross between the female parent 'R10' and the male parent 'E20' which was conducted at Higashiomi-shi, Shiga-ken, Japan in April 2001. In September 2001, 50 seedlings were obtained and sown in pots in a greenhouse. One seedling was selected for its flower colour and growth habit. That seedling was propagated by cuttings and observed in a trial from April to September 2003. The botanical characteristics of that plant were then examined. As a result, it was concluded that the selected Calibrachoa plant is distinguishable from any other variety. The new variety was named 'Sunbelsuka'.
Tests & Trials: The tests and trials for 'Sunbelsuka' were conducted in a polyhouse during the summer of 2006 in St. Thomas, Ontario. The trial included a total of 20 plants of each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 25 cm baskets on April 20, 2006. Each basket contained 3 cuttings with a total of 7 baskets per variety. Observations and measurements were taken from 10 plants of each variety on July 5, 2006. All colour measurements were made using the RHS Colour Chart 2001.
