Origin & Breeding History: 'Sutcatrabl' was developed by the breeder, Har Stemkens, an employee of Syngenta Seeds B.V. in Enkhuizen, The Netherlands. It originated from a cross made in August of 1999 between the female parent designated 'B21' and the male parent designated 'B23'. A plant from the resultant progeny was selected in May of 2000 and this same plant was selfed. Seeds from this cross were sown in February of 2001 and in May of the same year 'Sutcatrabl' was selected based on criteria for earliness of flowering and plant growth habit.

Tests & Trials: The test and trial for 'Sutcatrabl' was conducted in a polyhouse during the spring of 2006 at BioFlora Inc. in St. Thomas, Ontario. The trial included 15 plants of each variety. Rooted cuttings were transplanted into 15 cm pots on April 25, 2006. Observations and measurements were taken from 10 plants of each variety on June 9, 2006. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
