Origin & Breeding History: 'Kerminiblue' originated from a controlled hybridization of the proprietary seedling designated 05-227-1, as the female parent, and the proprietary seddling 05-227-3, as the male parent. The new Petunia variety was bred and developed by the breeder David W. Kerley in August 2005, in Over, United Kingdom. 'Kerminiblue' was selected in May 2006 based on flower colour, flower size and plant growth habit. The new variety was first propagated by vegetative tip cuttings in September 2006, in Over, United Kingdom.
Tests & Trials: Trials for 'Kerminiblue' were conducted in a polyhouse during the spring of 2009 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants wree grown from rooted cuttings and transplanted into 15 cm pots on April 30, 2009. Observations and measurements were taken from 10 plants of each variety on May 27, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
