Deduced by the proportion of typical sterile plants and normal fertile plants in segregative generations derived from WA zhenqiuA/6078 that:I gene could inhibit the expression of Rf gene completely by the heterozygosity of 1 pair of Rf in genotype;and only reduce the expression of Rf genes with two heterozygous Rf genes in genotype ;but it would never inhibit the expression of Rf genes if the genotype included 3 pairs of heterozygous Rf genes. When Rf gene was homozygous,the / gene could not inhibit the expression of it.
