Abstract

Genetic control of moldavian type CMS was studied in inter-line crosses gamma 380-3-1M x A392 and gamma 380-3-1M x W8, where pollen restoration is observed in spite of the abscense of the dominant gene Rf3. It is determined that in these exceptional cases sterilizing action of the cytoplasm is overcome by two dominant genes-restorers marked as RfA and RfB. The RfA-gene acts in diploid cells of sporophyte, RfB-gene reveals its effect in haploid genotype of microspores. Both genes are incompatible in male and female gametes as they are allelic. Evidently the gene RfB can intensify the action of the main gene Rf3 and performs the role of its modifier.
