===Botanical history===
Rutabaga has a complex [[Taxonomy (biology)|taxonomic]] history. The earliest account comes from the Swiss botanist [[Gaspard Bauhin]], who wrote about it in his 1620 ''Prodromus''.<ref name="Sturtevant" /> ''Brassica&nbsp;napobrassica'' was first validly published by [[Carl Linnaeus]] in his 1753 work ''[[Species Plantarum]]'' as a [[variety (botany)|variety]] of ''[[Brassica oleracea|B.&nbsp;oleracea]]'': ''B.&nbsp;oleracea'' var. ''napobrassica''.<ref name="IPNI1">{{IPNI|id=60452368-2|accessdate=30 October 2009}}</ref> It has since been moved to other taxa as a variety, [[subspecies]], or elevated to species rank. In 1768, a Scottish botanist promoted Linnaeus' variety to species rank as ''Brassica&nbsp;napobrassica'' in ''[[The Gardeners Dictionary]]''.<ref name="IPNI2">{{IPNI |taxon=Brassica napobrassica |id=72249-3|accessdate=30 October 2009}}</ref>

Rutabaga has a [[chromosome number]] of 2''n''&nbsp;= 38. It originated from a cross between [[turnip]] (''[[Turnip|Brassica rapa]]'') and ''[[Brassica oleracea]]''. The resulting cross doubled its chromosomes, becoming an [[Allotetraploid#Allopolyploidy|allopolyploid]]. This relationship was first published by [[Woo Jang-choon]] in 1935 and is known as the [[Triangle of U]].<ref name="Dixon 2007">Dixon, G.R. 2007. ''Vegetable Brassicas and Related Crucifers.''
