    We investigated inheritance of a male fertility restoration in winter triticale with the sterilising cytoplasm of T. timopheevi. Generations F1, F2, and BC1 were derived from crosses between two male sterile lines with the cytoplasm T. timopheevi and 12 restorer inbred lines of S3–S14 generations. The distribution of fertile and sterile plants in segregating progenies indicates that at least four independent nuclear genes are involved in expression of fertility restoration. Male sterility was determined by recessive genes. The simultaneous presence of at least two dominant genes in two independent loci is required for fertility restoration. The precise determination of the role of identified loci on the base of obtained phenotypic distributions is difficult due to presence of plants with intermediate fertility and variation that can not be explained by simple segregation ratios.
