The invention concerns genetically modified wheat plants and the progeny arising these plants, and also a method of producing hybrid wheat using these plants. The genetically altered wheat utilizes homoeologous pairing to add a fertility restorer chromosome which contains telomeric chromatin which is homologous to another wheat chromosome which bears a recessive male sterility gene. The fertility restorer chromosome contains a major portion of alien chromatin from other wheat species, and also contains a male fertility restorer gene, and one or more marker genes. The genetic makeup of the wheat plant in one preferred form can be described as: 20'' + 4B(ms) + [4m (or 4th) - 4EL - 4BL]. These plants possess meiotic stability, and are used to produce hybrid wheat strains.
