(78 days) Synergistic F-1 hybrid.

Put a sparkle on your face next August with this handsome high-yielding bicolor. The long fat pointy ears, up to 9" with up to 18 rows, speak loudly of abundance and satisfy the most discriminating of palates. Tall 7' plants have plenty of good husk protection, long flag leaves and tillers for market growers who demand a strong easy-to-harvest plant. Ripened for Donna Aug. 23, 2010, from a June 3 sowing, two days ahead of her Bodacious RM. Tolerates R and ST.

Types of sweet corn

Normal Sugary (su): standard varieties with traditional sweet corn texture & flavor. Sugar converts to starch quickly, so eat them within a few days. Tend to have high yields and germinate well in cool soils.

Sugary Enhanced (se): more sugar than su, tender kernels & slightly longer storage time. The * indicates heterozygous (only one parent contributes the se gene); all others are homozygous (both parents se).

Supersweet (sh2): 4 to 10 times the sugar content of su and se. Conversion of sugar to starch occurs at a much slower rate. Stays sweet long after harvest. Extra shriveled seed does not germinate well in cool soil.

Synergistic: more sugar than se. Very tender with long harvest and storage windows. Can be homozygous or heterozygous se with added sh2 kernels.

TripleSweet® Sugary Enhanced: has homozygous se kernels, and 25% of these also contain the sh2 trait.

Corn

  • About 85–200 seeds/oz. Seeds per packet vary.
    • Open-pollinated selections average 100 seeds/oz
    • Normal sugary varieties 140 seeds/oz
    • SE cultivars with shrunken seeds 150-160 seeds/oz
  • Days to maturity are from emergence after direct sowing; for transplants, subtract 20 days.

Culture: Untreated sweet corn seed will not germinate in cold wet soil. Please be patient and wait till soil warms to at least 60° before sowing, or start seedlings indoors and transplant at 3–6" before taproots take off. Minimum soil temperature 55°, optimal temperature range 65–85°. Tender, will not survive frost. Heavy nitrogen requirements.
