[Restoration of pollen fertility to cytoplasmic male sterile rye].

Thirteen homozygous inbred lines derived from European rye (Secale cereale L.) varieties were evaluated for their ability to restore pollen fertility to single crosses with the cytoplasmic male-sterile inbred line L1 - P as female parent. Two of the pollinator lines proved to be fully effective in restoring fertility. Eight lines were classified as nonrestorer genotypes. No conclusive results were obtained for the three remaining pollinator lines.
