Patent ID: 8865970

Claim:
A method for producing an angiosperm hybrid plant showing at least one yield-related heterotic phenotype, comprising: a. providing a mutant parent inbred angiosperm plant comprising a single mutation in a SINGLE FLOWER TRUSS (SFT) gene, wherein the mutation is such that it reduces SFT gene function when homozygous; b. providing a parent inbred angiosperm plant, homozygous for wild-type alleles of the SFT gene, the wild-type gene encoding a protein having the amino acid sequence set forth in SEQ ID NO:1; and c. crossing the mutant parent inbred angiosperm plant with the parent inbred angiosperm plant, homozygous for wild-type alleles of said SFT gene; thereby producing a heterozygous hybrid angiosperm plant comprising said wild-type SET allele and a mutated sft allele, wherein the heterozygous hybrid angiosperm plant shows at least one yield-related heterotic phenotype that is superior compared to a homozygous angiosperm plant having two wild-type alleles of said SFT gene.
