Origin & Breeding History: The variety 'Mos Thimint' originated from a cross made in January 2006 in Andijk, Netherlands. The female parent was a proprietary seedling designated CS06-29-7 and the male parent was a proprietary seedling designated CS06-4-1. The resultant seed was sown in a greenhouse in July 2006 in Andijk and in September 2006 a single plant from the progeny was selected, based on criteria for leaf colour and pattern, plant growth and plant habit.
Tests & Trials: Trials for 'Mos Thimint' were conducted in a polyhouse during the spring of 2011 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate variety and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 27, 2011. Observations and measurements were taken from 10 plants of each variety on June 15, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
