New Augmented Sweet Corn Offers Taste and Shelf Life

New augmented sweet corn varieties are taking the vegetable industry by storm as growers find consumers will pay up to twice the price for the tasty new varieties.

Breeders have found a great mix by combining the long shelf life trait of super sweet (SS) varieties with the sugary enhancer (SE) trait of great texture and taste.

The result is sweet corn that tastes better, lasts longer and is usually more tender – but in some instances can be prone to bruise. By many accounts, the taste outweighs the extra care that the corn requires.

This corn is referred to by a variety of names, many of them branded. The Illinois Seed Foundation calls their version Xtra Tender. Abbot and Cobb refer to one of their varieties as the Summer Sweet brand and offer it fresh in special tray packs as a premium product. Stokes Seed refers to theirs as the Gourmet line of sweet corn. Syngenta refers to its version as Triple Sweet. These branded lines are not the same genetically, but all feature a combination of the once-distinct traits.

Blake Meyers, with Seigers Seeds, said these augmented varieties are starting to catch on within the roadside marketing community. In that market, the conversion to these varieties could be as far 40-50% of the production.

“Some of the standard SEs are losing part of their market share with the conversion to these new varieties,” Meyers said.

Many of them are new to the market. So much so, Meyers said, that a year ago nobody knew what to call the sweet corn varieties in general. So far they have been very popular with direct retailers. While wholesalers have dabbled in the new corn, their hesitation may be because some of the varieties with the highest quality in taste are tender to machine harvesting, Meyers said.

Dave Mackenzie, president of Centest Seed Company, said that their Mirai brand sweet corn has been doing great for farm marketers and roadside stand operators.

While the variety has not made it into the retail environment on a large scale, Mackenzie said that a few growers have made successful forays into some chains. In particular, one grower supplied his local Wegmans on the Eastern Seaboard, and created quite a stir – especially when he ran out of corn.

Mackenzie said the variety, like many augmented varieties, fares much better if it is handpicked.

“What we are finding out so far is that our product is getting into the high quality niches,” Mackenzie said. “It is the leading variety in Japan because of taste. When the consumer tries it, they know it is different.”

Mirai was introduced in Japan in 1995. The variety was so successful there, it managed to change the preferred color of the market. Here in the North America, the brand does well with the roadside market, as well.

“Because it has been considered hard to grow, we’ve placed it with people we consider to be excellent marketers and urged them to double the price,” Mackenzie said. “Once people have tasted it, there is not issue with prices.”

Marketing is key

These new genetics have managed to expand sweet corn into countries that never had much interest, said Bryant Long, vice president of product development and breeder at Abbott and Cobb.

“So many other vegetables are declining, and sweet corn is booming. It has a lot to do with new genetics,” he said.

But the product still needs to be marketed well.

“Consumers are looking for superior products,” Long said. “They want things that will deliver the benefits of taste and nutrition. Their demands are what drove the company to present the product in a more formal presentation.”

That formal presentation has taken the shape of a sweet corn tray pack, sold with the corn partially husked. The company is working to develop brand recognition with the prepackaged Summer Sweet brand corn. Long said company president Art Abbott was one of the pioneers of packaged sweet corn – beginning to work with concepts nearly 15 years ago.

Better genetics

Some varieties of augmented sweet corn have a very long shelf life, which is something that the grower can use to extend his harvest time, said Dean Cotton, with Seedway.

“The newer varieties allow the grower to expand harvest time, and allow the retailer more product shelf life,” said Cotton. “You’ve got a much greater flexibility, and you have a more palatable product that is easier to get off the cob, and it gives you a more pleasing texture.”

The down side is that it is not a product that lends itself to a lot of rough handling, Cotton said. While the shipping trade hasn’t embraced it yet, they may eventually as they go through the learning curve of producing the corn.

Cotton said the varieties would continue to provide benefits to the growers as they are improved, as well.

“One of the next steps is improving disease resistance,” he said. “Many of the companies are working to have improved disease tolerances on these types and that will give it greater grower acceptance.”
