IFSI began its sweet corn program in the early 1960s when the value of the shrunken2 gene was identified. Shrunken2 varieties of sweet corn are unique in their ability to maintain a sweet flavor over an extended period. A genetic block in the biosynthesis of sugar to starch maintains high levels of sugars in the kernels of "Xtra-Sweet" and "Xtra-Tender" sweet corn products. These higher levels of sugars are preserved as the natural accumulation of starch is nearly stopped.
