what kind of corn is this?
There is absolutely no way to tell from a somewhat blurry photo. I can Identify that it is an all yellow cultivar, and not a bi color or white variety. =)
The most common types of sweet corn grown are a type of Sugary Enhanced variety, in the mid range of sweetness when it comes to corn. Supersweet or open pollinated are almost always grown by gardeners.
Also, your post might have had more luck in the "name that plant" forum.
