Origin & Breeding History: '92Y53' is the result of a cross between 92M91 x 91M91 that occurred in 2003 in Puerto Rico. Bulk, modified single seed descent and single plant selection methods were used in developing the variety. It was evaluated in yield test nurseries from 2006 to 2009. Contra season nurseries were used to advance the development of the variety. Selection criteria included yield, maturity and pest and disease resistance.

Tests & Trials: Tests and trials were conducted during the 2010 growing season in Wallaceburg, 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 201000114 from the Plant Variety Protection Office, Beltsville, Maryland, USA.
