Abstract
A breeding method of a polyploid rice two-line restorer line includes determining hybrid parents for breeding the restorer line; breeding a restorer line of an indica sterile/japonica restorer type, or breeding a restorer line of a japonica sterile/indica restorer type, and carrying out backcrossing or composite hybridization after hybridization of the parents; selecting a single plant that meets the breeding goal, carrying out composite hybridization again and carrying out preliminary molecular marker detection; comparing, and selecting a single plant with good traits for continuous selfing until the line is basically stable; selecting a stable line with good traits and detection molecular markers; carrying out test-crossing on the preferred line as a male parent with different types of polyploid sterile lines; and selecting a good hybrid combination and a restorer line thereof.
