Brassica
Brassica is a genus of flowering plants in the mustard family, Brassicaceae. It includes crops such as cabbage, broccoli, turnip, and rapeseed.
Brassicaceae: The flowering-plant family commonly called the mustard or cabbage family. Brassica is one genus within this larger family.
Cabbage: A leafy vegetable formed by a compact head of overlapping leaves, usually from Brassica oleracea. Cabbage is a familiar crop form derived from this genus.
U triangle: A model describing the relationships among three diploid and three allotetraploid Brassica crop species. It explains how ancestral species and hybridization produced several crop genomes.
Raphanus: A genus of flowering plants that includes radish and belongs to the mustard family. Radish is a familiar mustard-family crop outside Brassica.
Brassica oleracea: A Brassica species that includes cabbage, kale, broccoli, cauliflower, and several other cultivated forms. Its crop varieties show how selection diversified one species.
Broccoli: A vegetable whose edible flower buds and stems come from Brassica oleracea. Its harvested flower clusters are one of the genus's best-known foods.
Allopolyploidy: A form of polyploidy in which chromosome sets come from different species through hybridization. It underlies the origins of several cultivated Brassica species.
Sinapis: A genus of flowering plants in the mustard family that includes white mustard. Its mustard crops are related to, but taxonomically separate from, Brassica.
Brassica rapa: A Brassica species that includes turnips, Chinese cabbage, and several leafy vegetables. It is another species whose cultivated forms span distinct vegetables.
Cauliflower: A vegetable with a dense, undeveloped flower cluster, usually from Brassica oleracea. It is a crop form of the same species as broccoli and cabbage.
