origin of supersweet corn?

Dear Carol:
The following paper reports the first observation of the mutation, sh2,
which arose in 12-year-old seed of an inbred line, LA.  This is the
original recessive factor contributing the supersweet property (more
recently, this term has begun to be used for other genetic types), and
could be properly viewed as a spontaneous mutation.  Much biochemical and
mutational work has been done with this mutation.

Mains, EB. 1949. J Hered 40:21-24.  Heritable characters in maize. Linkage
of a factor for shrunken endosperm with the a1 factor for aleurone color.

For a search, try going to Query MaizeDB, choose Full Text, and enter
super* or supersw*, or other choices.  This will give you returns of any
contents that contain the string.

I'm forwarding your note to the maize net - others might give further
information.  If you might, please pass along the internet source that
attributes supersweet to bioengineering.  Thanks.
