Origin & Breeding History: 'Sundapin' originated as a naturally occurring branch mutation of the variety 'AK-Pet3', discovered in June 2009. The new plant was propagated by cuttings and grown in a controlled environment at Miyazaki-shi, Miyazaki, Japan. A trial was carried out from June 2009 to August 2010 where the botanical characteristics of the variety were examined. After determining that the new variety was distinguishable from any other varieties, and uniform and stable in its characteristics, the new variety was named 'Sundapin'.
Tests & Trials: Trials for 'Sundapin' were conducted in a polyhouse during the spring of 2013 in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 10, 2013. Observations and measurements were taken from 10 plants of each variety on May 14, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
