Early humans recognised the edible value of many of these species and through
selection modified nearly every plant part to suit their needs. Such modifications include

Species grown as oilseeds include B. napus, B. juncea, B. rapa and B. carinata.
The vegetable Brassicaceae includes B. napus (rutabaga, Siberian kale), B. rapa (Chinese
