Current Trends in Cabbage Breeding
Head cabbage (Brassica oleracea L. var Capitata), commonly called cab bage is a member of Brassica oleracea, belonging to Cruciferae family. The chromosome pattern is 2n = 2x = 18.
Cabbage cultivars descended from wild non-heading Brassica and origi nated in the eastern Mediterranean and Asia Minor. The Greeks and Romans have cultivated several wild varieties since at least 2000 B.C., and later Romans disseminated cabbage throughout Europe. After a long time of artifi cial cultivation and selection, variation within and between subspecies of B. oleracea, such as cabbage, collard, Brussels sprouts, broccoli, cauliflower, and kohlrabi, came into use (Figure 1). The heading types were created in Eu rope in the 13th century, and was introduced to Canada and China in the 16th century, to U.S. in the 17th century, and introduced to Japan in the 18th century.
