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.

根据认叭真秋刀6078各衍生分离世代中典型不育株和正常可育株所占比例推断：基因型中仅包含1对杂合的Rf基因时，I对Rf的表达起完全抑制作用；基因型中包含2对杂合的Rf基因时，I仅对Rf的表达起削弱作用；当基因型中包含3对杂合的对基因时，I对Rf的表达不起抑制作用；I对纯合位点的Rf的表达不起抑制作用。
