Yang et al. (2002) have shown that species of Raphanus are derived from an ancestor that originated by hybridization between two different lineages of Brassica—the B. nigra clade and the B. rapa clade. Therefore, species of Raphanus are actually members of the genus Brassica. However, formal combinations under the genus Brassica have not yet been made.
