Brassica species within the triangle of U. Three diploid species (Brassica rapa, Brassica nigra and Brassica oleracea) which represent the AA, BB and CC genomes are shown. Also shown are three allotetraploid species (Brassica juncea, Brassica napus and Brassica carinata) which are hybrid combinations of the basic genomes. Diploid chromosome number (2n) is shown.
