The ae (amylose extender) gene is a modifier of agronomic value for sugary shrunken sweet corn

The ae gene is useful in making the su sh2 double mutant fully viable with the phenotype being similar to the Su sh2 single mutant. Because the ae gene is recessive, it is only expressed in about 25% of the kernels from high sugar hybrids with Ae su sh2:Tr7 (2) where Tr7 is an extra chromosome from Tripsacum carrying the Su allele, as covered in Research Corp.--U. Mass. patent #4,051,629.
