Selection criteria included yield, maturity and disease resistance.

Tests & Trials: Tests and trials were conducted during the 2010 growing season in Woodstock, Ontario. Plots consisted of 2 rows with a row length of 3.8 meters and a row spacing of 76.2 cm. There were 3 replications. Tests and trials were supported by the purchased test report number 201000104 from the Plant Variety Protection Office, Beltsville, Maryland, USA.
