Tap root
fibrous root if this is not correct try google or wikipedia
A beet is technically a root. So the root of the plant is the beet, and whatever that grows out of it is the actual 'plant' portion.
I think you refer to 'sugar beet' it is not any type of cane. It is a root crop with a tap root similar to beetroot. It is grown in cooler climates for sugar production.
