Sweet corn

Sweet corn is maize selected for kernels that retain more sugar than ordinary field corn. It is harvested while immature and eaten as a vegetable.

Maize: Maize is a cereal grain domesticated in the Americas and grown worldwide for food, feed, and industrial uses. Sweet corn is a maize type, distinguished mainly by how its kernels develop and taste.
Sugary1: Sugary1 is a maize gene whose mutant forms produce kernels with elevated sugar and a shrunken appearance when dry. This mutation gives classic sugary sweet corn its elevated sugar content.
Corn on the cob: Corn on the cob is a cooked or raw ear of maize eaten directly from its central stalk. It is a familiar way to eat freshly harvested sweet corn.
Teosinte: Teosinte is a group of wild grasses native to Mexico and Central America, closely related to cultivated maize. It is the wild ancestor from which maize was domesticated.
Maize kernel: A maize kernel is the seed of the plant, composed chiefly of an embryo, endosperm, and outer covering. The kernel’s endosperm stores sugars and starch that shape sweet corn’s texture.
Shrunken2: Shrunken2 is a maize gene involved in starch synthesis; certain mutations produce high-sugar, wrinkled kernels. Its mutation underlies many supersweet varieties, which retain sweetness longer after harvest.
Canning: Canning is a food-preservation method that seals food in containers and heats it to destroy harmful microorganisms. Canning preserves sweet corn kernels beyond their brief fresh-harvest season.
Maize domestication: Maize domestication is the process by which people transformed teosinte into cultivated maize in ancient Mexico. Sweet corn’s crop history begins with the domestication of maize.
Endosperm: Endosperm is nutritive tissue inside a seed that supplies resources to a developing plant embryo. Sweet corn mutations alter how carbohydrates accumulate in the kernel’s endosperm.
Amylopectin: Amylopectin is a highly branched glucose polymer and a major component of plant starch. Mutations affecting starch formation can leave more carbohydrate as sugar in sweet corn kernels.
