Origin & Breeding History: The variety 'Sunviocoba' originated by a controlled pollination made at Yokaichi, Shiga, Japan in April 2004. The female parent was a proprietary line designated 01V-132-1 and the male parent was a proprietary line designated VF177-3. Seeds from the cross were germinated and grown to maturity. One plant was selected by the breeder on April 2005 and propagated by cuttings. A pot trial was carried out from October 2005 to April 2006 where it was concluded that the new variety was distinct, uniform and stable.
Tests & Trials: Trials for 'Sunviocoba' were conducted in a polyhouse during the spring of 2010 in St. Thomas, Ontario. The trial included a total of fifteen plants of the candidate and reference varieties. The candidate variety was grown from rooted cuttings while the reference was grown from seed. All plugs were transplanted into 11 cm pots on May 11, 2010. Observations and measurements were taken from ten plants or parts of plants on June 7, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
