Broccoli, also known as Calabrese in England and much of Europe, is closely related to cauliflower, cabbage, brussels sprouts, and kohlrabi. There is considerable confusion in the scientific and lay literature regarding exact nomenclature. All these Brassicas will intercross readily and are classified in the same genus and species.

Zea mays (sweet corn for processing)
Last revised February 2, 2010
TYPES
A number of genes affect sweetness in corn. These are recessive mutants of the starchy gene found in field corn (Su) and their modifiers, and other genes. Normal sweet corn has the recessive mutant of field corn (su). Modifiers and other genes include the sugary-extender gene (se) and the supersweet or shrunken gene (sh2). These make up three major genetic classes of importance in commercial production :
