The leaf blade of 'Sunrekodou' is shorter and narrower than the leaf blades of the reference varieties. The incisions on the margin of the leaf blade are medium to deep for 'Sunrekodou' while they are very deep for 'Danmoon20'. The inner side of the lower petal of 'Sunrekodou' is a lighter yellow than the inner side of the lower petal of 'Dancat266'. The inner and outer side of the corolla tube is a darker violet for 'Sunrekodou' than for 'Danmoon20'

Origin & Breeding History: The variety 'Sunrekodou' originated from the heavy ion irradiation of in-vitro meristems of a proprietary torenia selection designated 06-13-7. The irradiation was conducted in April 2007 at the Institute of Physical and Chemical Research in Japan. All shoots developed from the irradiated meristems were grown in pots in the glasshouse and in January 2008, one plant was selected. The selected plant was propagated by cuttings and grown in trials from May to September 2008, at Higashiomi-shi, Shiga, Japan. The new variety of torenia plant was named 'Sunrekodou'.

Tests & Trials: Trials for 'Sunrekodou' 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 transplanted into 11 cm pots on April 29, 2011. Observations and measurements were taken from 10 plants of each variety on June 7, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
