About the Supersweet (sh2) Genotype

1.  Is a naturally occurring genetic mutation found in field corn.
2.  Called supersweet because of higher sugar content than other genotypes.
3.  Called shrunken because the dry seed appears shrunken due to less starch in the endosperm.
4.  Have more seeds per pound, generally, than s.u. and many s.e. varieties
5.  Hold sweetness longer than s.u and s.e. varieties.
6.  Have a thicker skin (pericarp), pleasingly crisp when fresh but becomes tough and chewy with age. 
     The exception is the Xtra-Tender series.
7.  Does not have the seedling vigor that others exhibit in cool, wet soil.
     Generally, so plant in warm soil that is likely to stay warm.
8.  Plant in blocks of at least 4 rows and isolated from other genotypes with at least a 2-track truck path.

**The Xtra-Tender Series
The Xtra-Tender series was developed by sweet corn breeder Jerry Wegner of Illinois Foundation Seeds at the sweet corn processing heart of central Wisconsin, in the central sands region near Plover.  These varieties combine the best features and benefits of the s.e. and sh2 genotypes.  From the s.e. genotype is taken sensationally tender kernels, with smooth texture.  From the sh2 genotype come the kernel’s extremely high sugar content and their ability to maintain quality after harvest or on the stalk over an extended harvest.  The series has been years in the making and, as with any breeding program, improvement are ongoing.
