SWEET CORN: OLD VARIETY, MODERN GROWING
Genetics: Up, Up, Up with the Sugar
I plan on eating sweet corn almost daily from about the middle of July until early autumn. I know the arguments against growing sweet corn in a backyard garden: It’s cheap at the farmstand and space-hungry in the garden. What’s more, the most modern, “supersweet” varieties hold their sweetness for days.
The supersweet varieties are truly supersweet. But “supersweet” is too much of a catchall term. Old-fashioned corn, the Papoon corn developed around 1750 by the Haudenosaunee Confederacy and still available today, is noted for its creamy texture and 9 percent sugar due to its SU gene. Unfortunately, those sugars start changing into starch as soon as an ear is harvested.

In the latter half of the 20th century, “Sugary enhanced” sweet corn came on the scene. The SE gene incorporated into sweet corn varieties jacked sugar levels up to 17 percent. More Sugar meant more time for sweetness to hold following harvest. SE kernels are very tender.
Soon after, another gene, SH2 or “shrunken-2,” was found, which pushed that sweetness even higher, up to 35 percent! Read more










Recently, as I opened and walked through the gate into my vegetable garden, I thought, hmmm, things are looking pretty spiffy in the garden. Even a seasoned gardener friend remarked, “There’s so much green!” And that green is not from weeds, but from neat rows of napa cabbages, large heads of lettuce in various shapes and shades of green, and dark green rows of arugula and mustard. Leafy tops of Watermelon radishes (the name from the look of the sliced roots, not any affinity in flavor) and sweet Hakurei turnips perched above swelling roots.
