Reports regarding the chromosomal architecture of Brassica genomes and genome relationship among various species of the genus appeared in the second quarter of the 20th century AD. In the second quarter genome relationship was elaborated through secondary associations, pachytene and somatic karyotypes. Genome analysis and preferential pairing were extensively utilized for characterizing Brassica genomes in the third quarter. In last quarter of the century molecular characterization supplemented the conventional analytical tools for understanding the infrastructure of Brassica genomes. Whether it is the breeding system analysis, chromosome morphology, meiotic associations or molecular characterization proves that Brassica is monophyletic origin and it descended from an unknown six chromosomal prototype. Scientific developments made in Brassica genetics, from genome analysis to genomics during the 20th century AD are generalized in this paper.
