Summary:The method comprises the following steps: selecting a sterile line as a first-generation female parent, and hybridizing the first-generation female parent with a first-generation male parent with saline-alkaline tolerance to obtain F1-generation hybrid seeds; performing selfing to obtain F2-generation seeds; sterile plants and fertile plants are selected from the F2-generation seeds, the fertile plants and the known sterile homozygous line are subjected to test cross, and a temporary maintainer line with saline-alkaline tolerance is bred; the fertile plants and the sterile plants are subjected to brother cross, and a sterile homozygous line with the saline-alkaline tolerance is bred; hybridizing the sterile homozygous line and the temporary maintainer line, and breeding complete sterile line seeds with saline-alkaline tolerance; breeding a restoring line with saline-alkaline tolerance; and matching and hybridizing the seeds of the complete sterile line and a restoring line with saline-alkaline tolerance to ob
