Origin & Breeding History: 'NCORNSP-024SCRI' was bred and developed by Dr. G. Craig Yencho, Meri K. Reeber, Dr. Kenneth V. Pecota and Dominic A. Gillooly at the North Carolina State University in Raleigh, North Carolina, U.S.A. The variety originated from an open pollinated cross that occurred between June and November 2014, between the proprietary breeding line 'NC8226-011ORN', as the female parent and pollen from an unknown male. The resulting seed was sown in December 2014 and the seedlings transplanted to 15 cm pots. Two vegetative cuttings were taken from each plant and propagated in April 2015. The resulting young plants were planted in field plots in June 2015. 'NCORNSP-024SCRI' was selected on August 20, 2015 at the Horticultural Crops Research Station in Clinton, North Carolina based on growth habit, vigour, branch architecture, leaf shape and colour.
Tests & Trials: The comparative trial for 'NCORNSP-024SCRI' was conducted in a polyhouse during the spring of 2019 at BioFlora Inc., in St. Thomas, Ontario. The trial included 20 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 15, 2019. Observations and measurements were taken from 10 plants, or parts of plants, of each variety on June 3, 2019. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
