Origin & Breeding History: The variety 'Imtracorbu' originated from a controlled cross pollination made in February 2005, at Syngenta Seeds B.V., in Enkhuizen, The Netherlands. The female parent was a proprietary line designated W3797-3 and the male parent was a proprietary line designated W4709-2. The resultant seed was sown in a greenhouse in March 2005. The new variety 'Imtracorbu' was selected as a single seedling in September 2005 in Enkhuizen, based on criteria for flower colour, plant habit and production characteristics.
Tests & Trials: Trials for 'Imtracorbu' were conducted in a polyhouse during the summer of 2010 in St. Thomas, Ontario. Trials included 15 plants each of the candidate and reference varieties. Rooted cuttings were transplanted into 15 cm pots on April 21, 2010. Observations and measurements were taken from 10 plants of each variety on June 2, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
