Origin & Breeding History: 'AMOZ0001' originated from a controlled cross conducted by the breeder Har Stemkens, an employee of Syngenta in Enkhuizen, the Netherlands, in April 2007, as part of a controlled breeding program. The cross was conducted between the female parent 'K1243-1' and an unknown male parent, both proprietary seedlings. In September 2007, the resultant seed was sown in a greenhouse from which a single plant was selected in March 2008 based on its plant growth habit, flower colour and production characteristics.
Tests & Trials: The comparative trial for 'AMOZ0001' was conducted in a polyhouse during the winter of 2015 and the spring of 2016 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 10 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots in May 2015. Observations and measurements showing early flowering of the candidate variety were taken from 10 plants, or parts of plants, on December 9, 2015 and all other observations and measurements were taken on April 26, 2016. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
