Patent ID: 8067667

Claim:
A breeding pair of plants, comprising: (a) a first plant having a homozygous recessive genotype that results in absence of male fertility, said plant further comprising: (1) a first exogenous nucleic acid molecule comprising a male-fertility restorer gene, operably linked to a first promoter, and (2) a second exogenous nucleic acid molecule encoding a first hpRNA comprising a nucleotide sequence of a second promoter, wherein said first plant exhibits male fertility; and (b) a second transgenic plant, comprising a homozygous recessive genotype that results in absence of male fertility, said plant further comprising: (1) a third exogenous nucleic acid molecule comprising a male-fertility restorer gene, operably linked to said second promoter, and (2) a fourth exogenous nucleic acid molecule encoding a second hpRNA comprising a nucleotide sequence of said first promoter, wherein said second plant exhibits male fertility.
