Partial Fertility

Three inbred lines of rye (Secale cereale L.) known to be capable of restoring fertility to a cytoplasmic male-sterile line were crossed with the sterile line. The proportions of male fertile, partially male fertile and male sterile plants in F2 and backcross progenies indicated that three dominant restorer genes were present in each line. These were designated Rf1, Rf2 and Rf3, their relative expressivity was Rf1>Rf2>Rf3. Expressivity was dependent upon environment. Partial fertility occurred when certain genotypes carried two of the three alleles as dominant, but was dependent upon genotype and environment.
