The tribe Brassiceae is one of the 13-19 tribes which have been recognized within the family and is one of the few tribes believed to constitute a natural group. It is the most important economically and the most distinctive. The following publication is the third part of a guide to the wild germplasm of Brassica and allied crops. Artificial intergeneric hybridizations between various members of the tribe have been carried out on a large scale. Table 1 represents a summary of the literature compiled on inter-cytodeme hybridization between members of the tribe Brassiceae. Table 2 provides a summary of the 45 diploid cytodemes or crossing groups and six amphidiploid taxa described for Brassica coenospecies.
