Origin & Breeding History: 'Sunbelriapu' originated from a cross between the female parent '9PE1' and the male parent 'P3'. The cross was conducted in April 2003 at Higashiomi-shi, Shiga-ken, Japan. In September 2003, 50 seedlings were obtained from that crossing. Those seedlings were grown in pots in the glasshouse and evaluated. 'Sunbelriapu' was finally selected in September 2004 based on its growth habit, flower size and flower colour.

Tests & Trials: Trials for 'Sunbelriapu' were conducted in a polyhouse during the spring of 2008 in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 30 cm hanging baskets on May 23, 2008. Each basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants of each variety on July 22, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
