Origin & Breeding History: 'KLEPH15313' originated from a hybrid cross conducted by the breeder, Antonella Capo, in Latina, Italy. The cross was made between the female parent variety, 'PH-2012-3528', and the male parent variety, 'Surprise Marine', in April 2012. Seedlings were selected in April 2013, in Latina, based on the stability of the flower colour pattern and the plant quality. The selected seedlings were evaluated in multiple greenhouse trials between October 2013 and May 2014 and were assessed for cold tolerance, plant growth habit, plant quality, flower colour and flower colour pattern. 'KLEPH15313' was selected as a single seedling for commercialization in the fall of 2014, in Stuttgart, Germany.
Tests & Trials: The comparative trial for 'KLEPH15313' was conducted in a polyhouse during the spring of 2018 in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 16, 2018. Observations and measurements were taken from 10 plants, or parts of plants, of each variety on May 25, 2018. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
