Origin & Breeding History: The variety 'Sunsurfcopaka' originated from controlled cross pollinations made from April to November 2005 at Higashiomi, Shiga, Japan. The female parent was an unnamed proprietary variety designated Px287-1 and the male parent was an unnamed proprietary variety designated Px612-1. Seeds from the pollination were germinated and grown to maturity. One plant was selected in September 2006, in a controlled environment at Higashiomi, Shiga, Japan, based on criteria for growth habit, flower size and flower colour. The selected plant was propagated by cuttings and grown in a pot trial from April to September 2007 where it was determined that it was distinct from other varieties and uniform and stable. The new variety was named 'Sunsurfcopaka'.
Tests & Trials: Trials for 'Sunsurfcopaka' were conducted in a polyhouse during the spring of 2011 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 20, 2011. Observations and measurements were taken from 10 plants of each variety on May 31, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
