'Sunbelchipi' has only one colour on the corolla. The secondary colour of 'USCALI17' is a dark ring around the transition to the corolla tube. The secondary colour of 'KLEC01055' is a yellow area on the lower lobe, extending from the corolla tube. The veins on the inner side of the corolla tube are moderately conspicuous in 'USCALI17', whereas they are weak in 'KLEC01055'.

Origin & Breeding History: The variety 'USCALI17' originated from a planned breeding program developed by the breeder in Japan. In May 1998, a controlled cross was conducted with the female parent CJ20-7, a seedling selection with magenta flowers, crossed with the male parent CJ19-2, a seedling selection with pink flowers. The seed was collected and sent to Gensingen, Germany for further breeding and selection. The new variety was selected as a single plant from the resulting progeny in June 1999. The selection criteria were growth habit, superior summer performance, large flowers and resistance to Thielaviopsis, a soil fungus.

Tests & Trials: The tests and trials for 'USCALI17' were conducted in a polyhouse in St. Thomas, Ontario, during the summer of 2004. The trial consisted of a total of 18 plants of each variety. All plants were grown from rooted cuttings, transplanted into 10 inch baskets on May 27, 2004. Each basket contained 3 cuttings, with a total of 6 baskets per variety. Observations and measurements were taken from 10 plants of each variety on July 16, 2004. All colour measurements were made using the RHS Colour Chart 2001.
