Origin & Breeding History: 'Sunbel 0579' was bred by controlled pollination of proprietary Calibrachoa selection designated '9P9' as the female parent and proprietary Calibrachoa selection designated '3137-1' as the male parent. The cross took place in April 2007 in an isolated area of the OMI Research and Development Centre of Suntory Flowers Ltd., in Shiga, Japan. Seeds resulting from the cross were germinated and grown to maturity. In September 2009, one plant was selected for its growth habit and flower colour. The selected plant was propagated by cutting and grown in pots in order to examine its botanical characteristics during trials conducted between April 2010 and September 2011. The new variety of Calibrachoa was named 'Sunbel 0579'.

Tests & Trials: The trial for 'Sunbel 0579' was conducted in a polyhouse during the spring of 2013 at BioFlora Inc. in St. Thomas, Ontario. There were a total of 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 30 cm diameter hanging baskets on May 7, 2013. Each basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants or parts of plants on July 2, 2013. All colour determinations were made using the 2007 Royal Horticulture Society (RHS) Colour Chart.
