Origin & Breeding History: '32-75' was derived from a cross made by Monsanto Canada, in Listowel, Ontario in 1996. The segregating generations were selected for oil content, lodging resistance, yield and glyphosate tolerance. At the F5 generation, one plant was selected from which '32-75' originates.

Tests & Trials: Tests and trials were conducted at Elora Research Station, of the University of Guelph, Elora, Ontario in the summers of 2003 and 2004. Plots consisted of 4 rows, 6 meters in length with a row spacing of 40 cm. There were 2 replications arranged in an RCB design.
