Origin & Breeding History: '34-65' was developed by Monsanto Canada Inc. in Listowel, Ontario. The variety originates from a cross made in 1996. Segregating generations were selected for oil content, standability and yield. Each generation was sprayed with "Roundup". At the F5 generation, one plant was selected from which '34-65' originated. Experimental designation was PR9040.

Tests & Trials: Test and trials were conducted during the summers of 2004 and 2006 at the Elora Research Station, of the University of Guelph, Elora, Ontario. Plots consisted of 4 rows per variety spaced 20 centimeters apart with a row length of 6 meters. There were two replicates arranged in an RCB design.
