Origin & Breeding History: The variety 'Sunrovein' originated from heavy ion beam irradiation on the variety 'Revolution Brilliantpink'. In November 1999, 5 Gy of ionic neon (135MeV) were irradiated on 128 pieces of in-vitro axillary buds of 'Revolution Brilliantpink' with the Ring Cyclotron at the Institute of Physical and Chemical Research. Two weeks later, elongated buds were grown from cuttings. In April 2000, a plant having vivid purplish red corolla with a deep purplish red pattern was selected. In January 2001, the plant was propagated by cuttings. The resulting plants were grown in pots in trials at the Omi R&D Centre of Suntory Flowers Limited. By October 2001, the botanical characteristics of the selected plant were examined. The new variety was named 'Sunrovein'.

Tests & Trials: Tests and trials for 'Sunrovein' were conducted in a polyhouse during the spring and summer of 2005 in St. Thomas, Ontario. The trials included a total of 15 plants of each variety. All plants were grown from rooted cuttings, planted into 15 cm pots on April 29, 2005. Observations and measurements were taken from 10 plants of each variety on June 9, 2005. All colour measurements were made using the RHS Colour Chart 2001.
