Later Ill 677a was determined to be sweeter than normal sugary corn because, in addition to the sugary gene, it also had another gene for sweetness named "sugary enhancer" by Dr. Alexander Brink at the University of Wisconsin.

    In the early 1970’s David Galinat, the founder and president of Mesa Maize, began crossing Ill 677a with a large group of high-quality sugary sweet corns, selecting for exceptional eating quality as he developed inbred lines. Mesa Maize homozygous sugary enhancer sweet corn hybrids are the result of this breeding work with their characteristic excellent eating quality and long holding ability.

    We have discovered that there are many genes in addition to se that make su sweet corn sweeter. We have combined these other factors and have introduced a new class:
                          Tablesweet™ (or TSW™ )
PARFAIT was the first hybrid available in this class.

    Most Mesa Maize hybrids are homozygous sugary enhancer crosses. They must always be isolated from Sh2 types, and eating quality is very much improved when isolated from normal sugary and heterozygous sugary enhancer hybrids.
Enjoy!
