Origin & Breeding History: 'USTUNI8902' originated from a controlled cross between a seed raised variety with red flowers as the female parent and a wild Petunia species as the male parent. The cross was made by the breeder, Ushio Sakazaki, in Shiga, Japan on April 28, 2001. The seed from the cross was collected and sent to Gensingen, Germany for further breeding and selection. The new petunia was selected as a single plant from the resultant progeny on June 18, 2002, in Gensingen, Germany. Selection was based on improved branching characteristics and growth habit.
Tests & Trials: The tests and trials for 'USTUNI8902' were conducted in a polyhouse at BioFlora in St. Thomas, Ontario in the spring of 2006. The trials included 15 plants of each variety. Rooted cuttings were transplanted into six inch pots on April 17, 2006. Observations and measurements were taken from 10 plants of each variety. All colour measurements were made using the 2001 Royal Horticultural Society Colour Chart.
