Origin & Breeding History: 'MB41007' was developed by the breeder, Zenon Lisieczko of Monsanto Canada Inc. in Listowel, Ontario in 1999. The segregating generations were selected for oil content, standability, yield and resistance to glyphosate herbicides. At the F5 generation, one plant was selected from which 'MB41007' originated.

Tests & Trials: Tests and trials for 'MB41007' were conducted during the summers of 2005 and 2006 at the Elora Research Station, Elora, Ontario. Plots consisted of 4 rows which were 5 meters in length and a row spacing of 35 cm. There were 2 replicates arranged in a Random Complete Block Design.
