Origin & Breeding History: 'BHTUN6202' originated from a controlled cross conducted by the breeder between the female parent variety 'USTUNI8902' and the male parent variety 'Asukura roman'. The cross was conducted in Bonsall, California, USA on August 2, 2010. The new petunia variety was selected as a single plant from the resultant progeny on May 12, 2011. Selection was based on time of flowering, length of flowering period, number of flowers and plant shape throughout the season. 'BHTUN6202' was first propagated by vegetative tip cuttings on May 12, 2011 in Bonsall, California.

Tests & Trials: Trials for 'BHTUN6202' were conducted in a polyhouse during the spring of 2013 in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 10, 2013. Observations and measurements were taken from 10 plants of each variety on May 12, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
