A hypothetical scheme is given for the evolution of the different types of cauliflower (Brassica oleracea var. botrytis L.). This has been useful in identifying sources of reduced susceptibility to cabbage root fly (Delia radicum (L.)), and may also be useful in the search for reduced susceptibility to clubroot (Plasmodiophora brassicae Woron.). It is argued that knowledge of the phylogeny of types within each crop species is of great importance in the exploitation of genetic resources.
