Origin & Breeding History: 'WNCALSBDBLYEL23' originated from a controlled cross conducted on May 9, 2018 in Higashiomi, Shiga, Japan between the female parent variety 'Sweet Clingel Double Bronz' and the male parent variety 'Million Bells Gran Yellow'. From the resulting progeny, the new variety was selected on May 8, 2019 in Bonsall, California, USA based on flower colour, flower type, branching, abundance of flowers, flowering frequency and timing. Asexual reproduction of 'WNCALSBDBLYEL23' was first conducted by cuttings on May 10, 2019 in Bonsall, California, USA.

Tests & Trials: The comparative trial for 'WNCALSBDBLYEL23' was conducted in a polyhouse during the summer of 2023 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 April 29, 2023. Each basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants, or 10 parts of plants, on June 7, 2023. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
