Summary: 'Tra Tercot' differs from the reference varieties, 'Sakcadnucop' and 'KLEOE06151', mainly in leaf shape, inflorescence diameter, ray floret length, ray floret colour and disc diameter. The leaves of 'Tra Tercot' are obovate and spatulate in shape whereas they are elliptic in both reference varieties. The inflorescence of 'Tra Tercot' is medium in diameter whereas it is very wide in 'Sakcadnucop' and medium to wide in 'KLEOE06151'. The ray florets of 'Tra Tercot' are short to medium in length whereas they are long in 'Sakcadnucop' and medium to long in 'KLEOE06151'. The main colour of the upper side of the ray florets of 'Tra Tercot' is orange brown streaked with brown purple whereas it is purple in 'Sakcadnucop' and light yellow in 'KLEOE06151'. The secondary colour on the upper side of the ray florets of 'Tra Tercot' is another shade of orange brown whereas it is yellow brown in 'Sakcadnucop' and purple red in 'KLEOE06151'. The lower side of the ray floret of 'Tra Tercot' is yellow with green-brown stripes whereas it is orange-brown with purple stripes in 'Sakcadnucop' and orange-brown with yellow at the base and purple-brown in the centre in 'KLEOE06151'. Before dehiscence, the disc diameter of 'Tra Tercot' is smaller than that of both reference varieties.

Origin & Breeding History: 'Tra Tercot' originated from the cross using a proprietary seedling, 'OZ-185-1', as the female parent, with another proprietary seedling, 'OY-81-2', as the male parent, conducted in June 1999 in Andijk, the Netherlands. The resultant seed was sown in the greenhouse in August 2003. In January 2004, a single plant from the progeny was selected for flower quality and colour, and compact growth habit.

Tests & Trials: The trials for 'Tra Tercot' were conducted in a polyhouse at BioFlora in St. Thomas, Ontario, during the spring of 2007. The trials included 15 plants of each variety grown from rooted cuttings and transplanted into 11 cm pots. Observations and measurements were taken from 10 plants of each variety. All colour characteristics were determined using the 2001 Royal Horticultural Society (RHS) colour chart.
