Synergistic Whites

View Quick Facts Chart

Synergistic hybrids were developed in the early 1990’s in an effort to increase sugar levels of su / se types while maintaining the tender pericarp for which se types were famous. To achieve elevated sweetness along with excellent tenderness, the ears of these synergistic varieties combine approximately 25% supersweet (sh2) kernels with 75% se or su/se kernels. These delicious varieties are best used for fresh market sales, as long distance shipping is not recommended. Isolate from field corn, popcorn, ornamental corn and supersweet (sh and shA) types. For best results, isolate from Normal Sugary (su) types. “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."
