Mirai® Sweet Corn Seeds

Mirai® Sweet Corn Seeds

by Kristen Andersen

The Mirai® Sweet Corn seed breeding lines have been a popular choice for growers. In recent years, production challenges, seed crop failures and the seed no longer being produced by the supplier have made it increasingly difficult for Harris Seeds to source the high-quality Mirai® Sweet Corn seed that meets our valued customers' expectations.

To guarantee that only the best quality sweet corn seed is available for your production, we've made the difficult decision to remove the Mirai® Sweet Corn series from the Harris Seeds product line. We hope to re-introduce this series with confidence in the future, and we'll let you know when that happens.

To assist you in this transition, recommended substitute sweet corn seed varieties are described below. We hope you will find these suggestions helpful as you plan your next growing season, and welcome your questions or concerns regarding this change.

What Happened to Mirai® Sweet Corn Seeds?

Developed in Illinois, Mirai® Sweet Corn seeds are augmented supersweet varieties with exceptional sweetness. The varieties were initially marketed in Japan, where producers named the sweet corn seeds “mirai,” which roughly translates to “taste of the future.” Mirai® Sweet Corn varieties gained in popularity for a time, but have now been replaced with newer varieties, as is typical in the industry and happens over the span of about 10 years.
