Amylomaize was a term coined in the late 1940s by of Bear Hybrids Corn Company in Decatur, Illinois to describe his discovery and commercial breeding of a cornstarch with high (>50%) amylose content, also called high amylose starch. The discovery of amylomaize occurred as a mutation in a normal inbred line; from that one mutation an entire new kind of maize (corn) was developed.
