Origin & Breeding History: The variety 'NCORNSP-011MNLC' originated from an open pollinated cross made at North Carolina State University, Raleigh, North Carolina, USA. The female parent was a breeding clone designated 'NC1650-009N' and the male parent was unknown. The resultant seed was harvested between September 2003 and April 2004 and sown in a greenhouse during the last week of January 2005. The first cycle of selection was conducted on this seedling population for visual characteristics 4-6 weeks after germination. The selections were transferred to pots in a greenhouse to serve as virus-free source plants for future plantings. Two to three node cuttings of each source plant were taken in late April 2005 and transferred to rooting flats. These cuttings were planted in field trials during June and July of 2005 at the Horticultural Crops Research Station in Clinton, North Carolina. The new variety, 'NCORNSP-011MNLC' was selected as a single plant on September 1, 2005, based on a combination of characteristics including plant growth habit and vigour, and foliage colour and shape.
Tests & Trials: The trial of 'NCORNSP-011MNLC' was conducted in a polyhouse during the spring of 2010 in St. Thomas, Ontario. It included 15 plants of each variety. All plants were grown from rooted cuttings transplanted into 15 cm pots on April 30, 2010. Observations and measurements were taken from 10 plants or parts of plants of each variety on June 3, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
