Sweet corn

Sweet corn (''Zea mays'' convar. ''saccharata'' var. ''rugosa''), also called sweetcorn, sugar corn and pole corn, is a variety of maize grown for human consumption with a relatively 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. Sweet corn is picked when still immature (the milk stage) and prepared and eaten as a vegetable, unlike field corn, which is harvested when the kernels are dry and mature (dent stage). 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.

It is one of the six major types of corn, the others being dent corn, flint corn, pod corn, popcorn, and flour corn.
