Supersweet Standard Yellows

View Quick Facts Chart

Standard Supersweets have a shrunken (sh2) gene. This gene raises the original levels of complex sugars and extends their flavor by slowing the conversion to simple sugars and finally to starch. Moisture is also retained longer in this type and their shelf life is remarkably long. The kernel texture of this type is noticeably crunchier and firmer than the other genetic types. Growers should wait for ideal soil conditions (soil temperatures of at least 60-65° F. and moist but not saturated soil) before planting. This class will also germinate better if not planted too deep. Depth should be determined by soil moisture level in the field. All supersweet corns can be planted with other supersweet corns, but should be isolated from all other genetic types to ensure their eating quality. “Isolation” as used above can either mean at least 250 ft. apart, separated by an effective wind break, or 10 to 14 days difference in maturity because corn is wind pollinated.

The Harris Seeds company began catalog operation in 1879. It evolved from the efforts of Joseph Harris who was extremely successful in the selection of superior strains of vegetables and grains. The company became wildly popular because of his basic business philosophy - "Offer my customers a quality product at a fair price and they will return."
