TripleSweet ® Plus
These are the original sweet corn types used by your grandparents. Today, su types are known for superior seed quality, but generally lack appeal to the fresh market consumer. This is largely due to the lower sugar levels and rapid conversion of sugar to starch severely limiting the shelf life of the su varieties. Contains 9 to 16 percent sugars.
The se types have dramatically increased in popularity because of their sweetness, texture, and consumer appeal. Se types also have an increased shelf life compared to the su types. Its sweet taste and creamy texture are preferred by many growers.
Popularity of sh2 varieties continues to increase due to the high sugar content and field holding ability. Very sweet, sh2 varieties have a pleasant crunch and hold up 4 to 6 days in the fridge. These varieties need complete isolation from all other types of corn. Contains 28 to 44 percent sugars.
SSW varieties deliver enhanced seed quality,
TripleSweet is a new class of sweet corn that has up to 75 percent sugary enhanced se kernels and up to 25 percent Supersweet sh2 kernels. TripleSweet varieties combine the exceptional tenderness and sweet corn flavor of se types with extra sweetness, extended shelf life and field holding ability. TripleSweet varieties do not need to be isolated from se and su types and tolerate cool soil conditions. Known for lasting sweetness even under drought stress, TripleSweet is ideal for today’s gardener.
TripleSweet Plus is the next generation TripleSweet that has up to 60 percent sugary enhanced se kernels and up to 40 percent Supersweet sh2 kernels. TripleSweet Plus provides an exceptional eating experience due to an improved corn flavor that comes from the tender and creamy se kernels and an extra “pop” of sweetness from the sh2 kernels. TripleSweet Plus still has an extended shelf life, great field holding ability, and exhibits lasting sweetness even under drought stress. TripleSweet Plus varieties need not be isolated from se and su types and tolerate cool soil conditions.
