Maize plant having increased seed yield through recessive genetic determinants that confer expanded corn ear tips

摘要

This invention provides a novel means of making maize hybrids and inbreds with expanded ear tip phenotypes for promoting increased seed yield from recessive genetic determinants. This is achieved by making standard inbred×hybrid as well as inbred×inbred crosses followed by selection in the subsequent self-pollinated generations from these plants for expanded ear tip phenotype characteristics to produce new parent inbred lines. Next, the resulting inbreds, having a different pedigree but possessing the recessive expanded ear tip genetic determinants, are crossed to cause the expanded ear tip trait to express as a homozygous recessive trait in an otherwise primarily heterozygous hybrid.
