Sweetness – Make sure that your corn variety has excellent eating quality and sweetness. This is vital to ensure repeat business from consumers.
Field Holding Ability – If you are a small or one-person operation, picking sweet corn right on the maturity date can be challenging. Consider planting varieties that will give you a wider picking window, such as the augmented supersweet varieties.
Ear Size - In my experience, I have found that if you are wholesaling to restaurants, they want a smaller ear that will fit on a plate with the best eating quality possible. With its shorter ear size, Mr. Mini Mirai is ideal for restaurant sales. At farmers’ market and roadside stands, the consumers are more likely to seek an impressive, large ear, which has a great eating quality. Keep these criteria in mind when selecting which sweet corn varieties to grow.
Cold Soil Tolerance and Maturity – If you tend to have cooler soil temperatures in spring and it’s tougher to get into the fields to plant, you may want to really look at sweet corn varieties that have good cold soil tolerance. You tend to see better cold soil tolerance with se and synergistic se varieties, but breeders are now introducing supersweet varieties that have decent cold soil tolerance. Most growers will plant early, mid-season, and late varieties to ensure a constant supply of fresh sweet corn throughout the season.
With sweet corn, ensuring that you’ve selected the correct varieties that will perform to their maximum potential is the key to ensuring you repeat business and bigger profits. Keep these things in mind when choosing which varieties to grow and you are sure to have a profitable season.
