Description:
'32-75' is a Roundup Ready open pollinated spring canola variety. The cotyledons are medium in width. Leaf blades are medium green in colour with a few lobes present. The leaf margin is sharp with dentations that are shallow in depth. The leaves are short to medium in length and narrow in width. '32-75' has yellow flower petals. The siliques are short to medium in length with a short to medium beak and pedicel length. The plants are short to medium in height. Seed colour is black. '32-75' has low erucic acid content and low glucosinolates. '32-75' has fair to good lodging resistance. '32-75' is resistant to glyphosate herbicides.
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.
