The Brassica crops provide the greatest diversity of products derived from a single genus. As vegetables they deliver leaves, flowers, stems and roots that are used either fresh or in processed forms. This book covers the Occidental crops derived from B. oleracea (cole or cabbage group) and Oriental types from B. rapa (Chinese cabbage and its relatives). Both groups are of immense importance for human nutrition, containing vital vitamins and cancer preventing substances.
