List of sweetcorn varieties
This is a list of the most commonly cultivated varieties of sweet corn, and the number of days from germination of corn plant to harvest.
Standard (SU)
The oldest type of sweet corn, which contains more sugar and less starch than "field" corn intended for livestock. Tends to be hardier in respect to planting depth, germination and growth than other types. Begins conversion of sugar to starch after peak maturity or harvest, and as such is best when harvested and eaten immediately.

Sugary Extender (SE)
Contains even more sugars in relation to starch than su types, and as such is able to retain sweetness for 2 to 4 days with proper refrigerated handling. Somewhat less hardy than su types. Is known as a "tender" kernel and as such does not lend itself to mechanical handling. Does not require isolation from su pollen, although it is preferred.

Supersweet (Sh2)
Supersweet or shrunken-2 types have as much as two to three times the sugar content of su or se types, with proper handling is able to be stored for up to 10 days if properly handled. Less hardy than even se types, requiring higher germination temperatures, precise planting depth and isolation from all other corn pollen for optimum results. The name derives from the shrunken, shrivelled appearance of the dried kernel which is low in starch.
