Origin & Breeding History: 'Divoro' was developed by the breeder Har Stemkens, an employee of Syngenta Seeds B.V., in Enkhuizen, The Netherlands. The variety originated from a controlled cross made in August 2001, in Enkhuizen, between the female parent 'Diastu' and the male parent 'C0004-2'. A single plant was selected from this cross in May 2002, based on criteria for compact habit, earliness, flower colour and field performance. Asexual reproduction by vegetative cuttings was first conducted in June 2002.

Tests & Trials: The trials for 'Divoro' were conducted in a polyhouse during the spring of 2006 in St. Thomas, Ontario. The trial included a total of 15 plants of each variety. All plants were grown from rooted cuttings transplanted into 11 cm pots on March 31, 2006. Observations and measurements were taken from 10 plants of each variety on May 17, 2006. All colour measurements were made using the 2001 RHS colour chart.
