“From unexciting commodity
to attractive snack”
“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!
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.
