The female parent was a proprietary seedling designated 01-M169 and the male parent was the variety 'Yogwendolyn'. The resultant seed was sown in a greenhouse in Alva, Florida in June 2005 and a single plant was selected from the progeny in October 2005, based on criteria for flower colour, flower size and plant habit.
Tests & Trials: Trials for 'Synberna Yel' were conducted in an outdoor irrigated trial during the summer of 2010 in St. Thomas, Ontario. The trial included a total of 15 plants of each variety. All plants were grown from rooted cuttings and transplanted into 20 cm pots on June 29, 2010. Observations and measurements were taken from 10 plants of each variety on September 14, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
