Origin & Breeding History: The variety 'DISZ0001' originated from a controlled cross made in May 2006 at Enkhuizen, Netherlands. The female parent was a red flowered proprietary seedling, designated H0026-1 and the male parent was a red flowered proprietary seedling, designated D29. The resultant seed was sown in a greenhouse in February 2007. In May 2007, a single plant was selected from the progeny, based on criteria for flower colour, plant habit and production characteristics.
Tests & Trials: Trials for 'DISZ0001' were conducted in a polyhouse during the summer of 2012 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 11 cm pots on April 24, 2012. Observations and measurements were taken from 10 plants of each variety on June 26, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
