Q:Information:  - 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. Because each kernel has a hard outer layer to protect the soft endosperm, it is likened to being hard as flint; hence the name.  - The Andropogoneae, sometimes called the sorghum tribe, are a large tribe of grasses (family Poaceae) with roughly 1,200 species in 90 genera, mainly distributed in tropical and subtropical areas. They include such important crops as maize (corn), sugarcane, and sorghum. All species in this tribe use C carbon fixation, which makes them competitive under warm, high-light conditions.  - Forage is plant material (mainly plant leaves and stems) eaten by grazing livestock. Historically, the term "forage" has meant only plants eaten by the animals directly as pasture, crop residue, or immature cereal crops, but it is also used more loosely to include similar plants cut for fodder and carried to the animals, especially as hay or silage. The term forage fish refers to small schooling fish that are preyed on by larger aquatic animals.  - Dent corn also known as yellow dent corn, Reid's yellow dent corn, white dent corn, or field corn, is a variety of maize or corn with a high soft starch content. It received its name because of the small indentation ("dent") at the crown of each kernel on a ripe ear of corn. It is a variety developed by northern Illinois farmer James L. Reid. Reid and his father, Robert Reid, moved from Brown County, Ohio to Tazewell County, Illinois in 1846 bringing with them a red corn variety known as "Johnny Hopkins", and crossed it with varieties of flint corn and floury corn. Most of today's hybrid corn varieties and cultivars are derived from it. This variety won a prize at the 1893 World's Fair.  - Panicoideae is the second - largest subfamily of the grasses with over 3,500 species , mainly distributed in warm temperate and tropical regions . It comprises some important agricultural crops , including sugarcane , maize ( or corn ) , sorghum , and switchgrass . C4 photosynthesis evolved independently a number of times in the subfamily , which presumably had a C3 ancestor .  - Maize (; "Zea mays" subsp. "mays", from after Taíno "mahiz"), also known as corn, is a large grain plant first domesticated by indigenous peoples in Mexico about 10,000 years ago. The six major types of corn are dent corn, flint corn, pod corn, popcorn, flour corn, and sweet corn.  - Sorghum is a genus of plants in the grass family. Seventeen of the twenty-five species are native to Australia, with the range of some extending to Africa, Asia, Mesoamerica, and certain islands in the Indian and Pacific Oceans.  - Indigenous peoples, also known as first peoples, aboriginal peoples, native peoples, or autochthonous peoples, are ethnic groups who are descended from and identify with the original inhabitants of a given region, in contrast to groups that have settled, occupied or colonized the area more recently. Groups are usually described as indigenous when they maintain traditions or other aspects of an early culture that is associated with a given region. Not all indigenous peoples share such characteristics. Indigenous peoples may be settled in a given locale/region or exhibit a nomadic lifestyle across a large territory, but they are generally historically associated with a specific territory on which they depend. Indigenous societies are found in every inhabited climate zone and continent of the world.  - Sugarcane, or sugar cane, are several species of tall perennial true grasses of the genus "Saccharum", tribe Andropogoneae, native to the warm temperate to tropical regions of South Asia and Melanesia, and used for sugar production. It has stout, jointed, fibrous stalks that are rich in the sugar sucrose, which accumulates in the stalk internodes. The plant is tall. All sugar cane species interbreed and the major commercial cultivars are complex hybrids. Sugarcane belongs to the grass family Poaceae, an economically important seed plant family that includes maize, wheat, rice, and sorghum, and many forage crops.  - Mexico (, modern Nahuatl ), officially the United Mexican States, is a federal republic in the southern half of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost two million square kilometers (over 760,000 sq mi), Mexico is the sixth largest country in the Americas by total area and the 13th largest independent nation in the world. With an estimated population of over 120 million, it is the eleventh most populous country and the most populous Spanish-speaking country in the world while being the second most populous country in Latin America. Mexico is a federation comprising 31 states and a federal district that is also its capital and most populous city. Other metropolises include Guadalajara, Monterrey, Puebla, Toluca, Tijuana and León.  - Flour corn ("Zea mays" var. "amylacea") is a variety of corn with a soft starchy endosperm and a thin pericarp. It is primarily used to make corn flour.  - Popcorn is a type of corn that expands from the kernel and puffs up when heated. Popcorn is able to pop like amaranth grain, sorghum, quinoa, and millet. When heated, pressure builds within the kernel, and a small explosion (or "pop") is the end result. Some strains of corn are now cultivated specifically as popping corns.  - Sucrose is a common, naturally occurring saccharide found in many plants and plant parts. Saccharose is an obsolete name for sugars in general, especially sucrose. The molecule is a disaccharide combination of the monosaccharides glucose and fructose with the formula CHO.  - Saccharum is a genus of tall perennial plants of the broomsedge tribe within the grass family.  - Sweet corn ("Zea mays" convar. "saccharata" var. "rugosa"; also called sugar corn and pole corn) is a variety of maize with a high sugar content. Sweet corn is the result of a naturally occurring recessive mutation in the genes which control conversion of sugar to starch inside the endosperm of the corn kernel. Unlike field corn varieties, which are harvested when the kernels are dry and mature (dent stage), sweet corn is picked when immature (milk stage) and prepared and eaten as a vegetable, rather than a grain. Since the process of maturation involves converting sugar to starch, sweet corn stores poorly and must be eaten fresh, canned, or frozen, before the kernels become tough and starchy. History. Sweet corn occurs as a spontaneous mutation in field corn and was grown by several Native American tribes. The Iroquois gave the first recorded sweet corn (called 'Papoon') to European settlers in 1779. It soon became a popular food in southern and central regions of the United States. Open pollinated cultivars of white sweet corn started to become widely available in the United States in the 19th century. Two of the most enduring cultivars, still available today, are 'Country Gentleman' (a Shoepeg corn with small kernels in irregular rows) and 'Stowell's Evergreen'.
