Brassica genome sizes

At present the size of the various Brassica species genomes can only be estimated. There are several established methods of estimation, including Feulgen microdensity measurements and flow cytometry. The values quoted are the haploid genome (1C) equivalents in Mbp. For information on the genome composition and U's triangle see here link
