Sweet Corn

Four New Sweet Corn Inbreds Containing the sh2 Allele

Sweet corn results from a mutation at the sugary locus (su), which causes the endosperm of the seed to accumulate twice as much sugar as field corn. New mutants (sh2 and se) have been developed to improve sweet corn’s sweetness and other qualities. Several new sweet corn inbreds carrying the sh2 mutation have now been developed. Three of the inbreds have been tested in hybrid combinations for at least three seasons and yield hybrids with good to excellent quality. These inbreds have yellow germplasm. A fourth inbred line has very high quality, flavor, and texture and is useful as a male.

A Multiple-Eared Inbred Line (W701BC) of Corn for Production of “Baby Corn”

Baby corn is produced by harvesting immature ears of corn just after the silks develop. Generally, corn plants produce from one to three ears per plant. This invention describes a variety of corn that produces a high yield of baby corn. This homozygous, phenotypically stable variety, called W701BC, produces 15 or more ears per plant in good conditions. Additionally, at approximately three feet tall, this variety is relatively short and therefore easier to harvest by hand.


Increases yield of baby corn

Additional ears grow on main stalk and tillers

Compact stature makes harvest convenient

Other commercially desirable traits may be added via backcrossing
