In progeny of the crosses, a self fertile plant with 42 chromosomes was selected and named R 20. From this plant several lines that possessed Rf (fertility restoring) genes and/or powdery mildew resistant genes were obtained. Apparently, the system of sterility-fertility of pollen can be applied for hybrid wheat production. In addition, the disease resistance may be used in breeding. The male fertile lines possessed one or more Ae. mutica sat-chromosome(s), which show the ability to suppress the nucleolar organizing regions of chromosomes 1B and 6B of common wheat. The relation between the sat-chromosomes and male fertility restoration is not yet clear.
