"Beta vulgaris (beet) is a plant which is included in the subfamily Betoideae of the family Amaranthaceae. It is the economically most important crop of the large order Caryophyllales. It has several cultivar groups: the sugar beet, of greatest importance to produce table sugar; the root vegetable known as the beetroot or garden beet; the leaf vegetable known as chard or spinach beet; and mangelwurzel, which is a fodder crop. Three subspecies are typically recognised. All cultivars fall into the subspecies Beta vulgaris subsp. vulgaris. The wild ancestor of the cultivated beets is the sea beet (Beta vulgaris subsp. maritima)." - (en.wikipedia.org 26.01.2020)
