Abstract
This patent pertains to a method of producing a waxy maize starch derived from a plant which is heterozygous for the recessive sugary-2 allele by interplanting waxy maize seed which is homozygous for the dominant sugary-2 allele and waxy maize which is homozygous for the recessive sugary-2 allele, one hybrid being male sterile. The maize is harvested and processed together to obtain starch with excellent low temperature and freeze-thaw stability, high pasting temperature, and intact granules.
Claims6
A starch derived from a blend produced by the method comprising the steps of:
- (a) interplanting two hybrids, wherein:
- (1) the first hybrid is a male fertile waxy maize seed;
- and
- (2) the second hybrid is a male sterile waxy maize seed which is homozygous recessive for the sugary-2 allele;
- (b) permitting the male fertile maize plants to pollinate said male sterile maize plants;
- and
- (c) harvesting the resulting maize seed from the two hybrids together to result in the blend of waxy maize heterozygous for the recessive sugary-2 allele and waxy maize which is homozygous for the dominant sugary-2 allele.
