All maize arose from a single domestication in southern Mexico about 9,000 years ago. The oldest surviving maize types are those of the Mexican highlands. Maize spread from this region to the lowlands and over the Americas along two major paths. [3] The centre of domestication was most likely the Balsas River valley of south-central Mexico. [4]
This map shows the sites of domestication for a number of crop plants. Places, where crops were initially domesticated, are called centers of origin. This is a list of plants that have been domesticated by humans. The list includes individual plant species identified by their common names as well as larger formal and informal botanical ...
These two plants provide complementary dietary amino acids. Improved bioavailability of maize was discovered using a special process involving limewater, which also added calcium. Maize is also associated with festival and feast foods. Before it was domesticated and became a main crop, maize was used as a basis for beer.
Cereals that became modern barley and wheat were domesticated some 8,000 years ago in the Fertile Crescent. [5] Millets and rice were domesticated in East Asia, while sorghum and other millets were domesticated in sub-Saharan West Africa, primarily as feed for livestock. [6] Maize arose from a single domestication in Mesoamerica about 9,000 ...
Maize, beans, and squash, whether grown individually or together, have a very long history in the Americas. [5] The process to develop the agricultural knowledge for cultivation took place over a 5,000 to 6,500 year period. Squash was domesticated first, with maize second and beans third.
(middle) sorghum, maize, oats (bottom) millet, wheat, rye, triticale. A cereal is a grass cultivated for its edible grain. Cereals are the world's largest crops, and are therefore staple foods. They include rice, wheat, rye, oats, barley, millet, and maize. Edible grains from other plant families, such as buckwheat and quinoa, are pseudocereals.
Flint corn (Zea mays var. indurata; also known as Indian corn or sometimes calico corn) is a variant of maize, the same species as common corn. [1] Because each kernel has a hard outer layer to protect the soft endosperm, it is likened to being hard as flint, hence the name. [2]
Genetic erosion is a menace to the basis of further improvement for a monoic [check spelling], allogamous species, Zea mays L., whose genetic progress is mainly founded on the combination of the structural and physiological traits, contributed by each parental genotype, and a hazard to the specific qualities of different maize varieties, selected throughout the centuries as a major element for ...
