The real joke is that most of the tinkering was to lower the erucic acid component, since that apparently caused serious problems in lab (mice ? rats ?), then years after Canola became popular it turned out that erucic acid seemed to cause problems in rodents but not in humans.

If I remember correctly, Canola was known as LEAR (Low Erucic Acid Rapeseed) for a quite a while...

Holy Canola, Batman !!
