Rf 2 , one of two major dominant genes needed to restore pollen fertility to the T‐type of cytoplasmic pollen sterile maize ( Zea mays L.), has been shown to be located on chromosome 9, approximately 5 crossover units from waxy endosperm (wx) and adjacent to the centromere. Results from tests involving chromosomal translocations and tests involving marker genes were in complete agreement.
