Fifty introductions of spring wheat, Triticum aestivum L., from throughout the world were crossed as males to a line of spring wheat containing the cytoplasm of T. timopheevi and the nucleus of ‘Selkirk.’ Three of the introductions (PI 167841, PI 277013, and PI 277016) contained genes for pollen fertility restoration. F 1 plants from crosses of two male sterile varieties containing T. timopheevi cytoplasm with PI 277013 and PI 277016 were almost completely fertile under our conditions. These two introductions from Spain provide an additional source of a gene, or genes, with pollen fertility restoration capabilities.
