Origin & Breeding History: The variety 'Petpasyel' originated from a controlled cross made in July 2002 in Cambridge, United Kingdom. The female parent was identified as 01-84-1 and the male parent was the variety 'Keiyeul'. The new variety was selected from the resultant progeny as a single plant in May 2003, based on criteria for growth habit, earliness, flower colour and consistency. Asexual reproduction was first conducted in August 2003 in Enkhuizen, The Netherlands.

Tests & Trials: The trials for 'Petpasyel' were conducted during the spring of 2007, in a polyhouse in St. Thomas, Ontario. The trials consisted of a total of 15 plants of the candidate and reference varieties. All plants were grown from rooted cuttings planted into 15cm pots on April 24, 2007. Observations and measurements were taken from 10 plants of each variety on June 5, 2007. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour chart.
