Embodiment Construction

[0019] This patent relates to a new method of producing corn grains with desired starch functionality which involves growing two different hybrid corns in the same field. One hybrid maize is homozygous for the two required recessive genes, while a second hybrid maize is recessively homozygous for one of these same genes and wild-type or dominantly homozygous for the other gene suitable.

[0020] Recessive genes include, but are not limited to, waxy (wx1), sugary-1 (su1), sugary-2 (su2), sugary-3 (su3), amylose extender (ae1), dull (du1), horny (h1 ), shrunken-1(sh1), shrunken-2(sh2), floury-1(f11), floury-2(f12), white endosperm(y1), and opaque series(o1-o14).

[0021] One hybrid corn is male sterile so that the second hybrid provides pollen for the entire field. Which hybrid maize is selected as the male sterile hybrid maize is irrelevant to the present invention. Specific selection of male sterile and pollinated plants determined the starch genotypes derived from these tw...

Abstract

A new method has been developed to produce corn grains with desired functionality, involving growing two different hybrid corns in the same field. The two hybrid corns are planted in alternating blocks consisting of rows. One hybrid is male sterile so that the second hybrid provides pollen for the entire field. This results in multiple blocks of two different types of grain, which can be harvested and processed separately.

Description

technical field [0001] The present invention relates to a method of producing two types of hybrid corn in a field so that they can be harvested independently. Background technique [0002] In the United States, corn is a commercial crop used for a variety of purposes including: a human food source, animal feed, and as a source of carbohydrates, oil, protein, and fiber. However, there is currently an increased market demand for corn with specific end-use characteristics, but corn grains with standard compositions cannot meet the above requirements. Often, special varieties of corn are distinguished from "normal" field corn by altered endosperm characteristics, such as general changes in the degree of starch branching (waxy corn and amylose supplementation), increased accumulation of sucrose or water-soluble polysaccharides (sweet , shrunken, super sweet corn) or altered endosperm firmness (food grade corn or popcorn). [0003] Increased demand for this particular variety of...
