“Until ten years ago, Rijk Zwaan breeders were mainly concentrating their efforts on traditional cucumbers,” recounts Eric Bal.

“Then we started looking across the borders of western Europe and saw the success of, among other things, mini cucumbers in the Middle East and ‘slicers’ in the US.

We are now collaborating closely with growers, trading companies, processors and supermarkets in order to make these concepts successful here as well.”

Corn Mini Yellow Mirai 003

"single serving" size! 5” long

A sensation in Japan, it's so popular here that folks

drive 100 miles or more to buy it at roadside stands!

Small bi-color double ears super sweet corn hybrid: variety of the future? Output: Great example

It was bred on the Ahrens family farm in Illinois by J. David Mackenzie At first, the new corn didn't seem marketable. It needs to be hand-picked, which ruled out production by the huge commercial farms in the U.S.

So Mackenzie introduced it instead to Japan, where small "boutique" farms are common, and many crops are still picked by hand.

Within a few years Mirai® had become the bestselling sweet corn in Japan, capturing an amazing 35% of the market from all other varieties!

Pkt is 100 seeds. $3.99.
