The resultant seed was sown in a greenhouse in September, 2006. In January 2007, a single plant was selected from the progeny based on flower colour, plant habit and production characteristics.

Tests & Trials: Trials for 'Tra Yel' were conducted in a polyhouse during the summer of 2011 in St. Thomas, Ontario. The trial included a total of fifteen plants each of the candidate and reference varieties. Rooted cuttings were transplanted into 11 cm pots on April 27, 2011. Observations and measurements were taken from ten plants or parts of plants on June 24, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
