Origin & Breeding History: The variety 'Sunsurf Akatora' originated from a cross between the variety 'PF411-5' as the female parent and the variety 'B268-1' as the male parent. The cross was conducted in July 2006, at Higashiomi-shi, Shiga, Japan. Seed was obtained from the cross, germinated and grown to maturity. In August 2007, one plant was selected for its growth habit, flower size and colour. The selected plant was propagated by cuttings and grown in pots, and then evaluated in a trial from April to September 2008.
Tests & Trials: Trials for 'Sunsurf Akatora' were conducted in a polyhouse during the spring of 2012 at BioFlora Inc. in St. Thomas, Ontario. The trial included 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 25, 2012. Observations and measurements were taken from 10 plants of each variety on May 28, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
