Varieties used for comparison: 'KLEC02004' (MiniFamous Peach) and 'Kakegawa S69' (Colorburst Melon)

Summary: The plants of 'USCALI214-1' are taller than those of both reference varieties. Intensity of anthocyanin colouration of the shoot is weak to moderate for 'USCALI214-1' while it is strong to very strong for 'Kakegawa S69' and very weak to weak for 'KLEC02004'. The main colour on the upper side of the corolla of 'USCALI214-1' is red pink with red secondary veins while for 'Kakegawa S69', it is light red pink with red pink near the mid-veins with orange red secondary veins and for 'KLEC02004', it is purple red along the margins fading to light red pink towards the base. The main colour on the lower side of the corolla lobe is light blue pink with purple red around the mid-veins for 'USCALI214-1' while for 'Kakegawa S69' it is light red pink with red pink around the mid-veins and for 'KLEC02004', it is blue pink around the mid-veins. 'USCALI214-1' has weak to medium undulation of the corolla margin while both reference varieties have medium to strong undulation of the corolla margin.

Origin & Breeding History: 'USCALI214-1' originated from a controlled cross between the female parent 'CJ03-98' and the male parent 'CJ03-110'. The cross took place on April 14, 2003 in Hikone, Shiga, Japan. The new Calibrachoa was selected as a single plant from the resultant progeny on June 4, 2004 in Gensingen, Germany and was then propagated by vegetative cuttings. 'USCALI214-1' was selected based on plant growth habit, heat tolerance, flower size and resistance to Thielaviopsis.

Tests & Trials: Trials for 'USCALI214-1' were conducted during the summer of 2007, in a polyhouse, in St. Thomas, Ontario. The trial included 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 30 cm hanging baskets on May 1, 2007. Each hanging basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants of each variety (except plant height where 5 plants were measured) on July 7, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
