Zusammenfassung:The invention relates to the technical field of wheat breeding, and discloses a breeding method of drought-resistant wheat. The breeding method comprises the steps of selecting drought-resistant wheatparent materials, performing hybridization to obtain F0-generation wheat, performing continuous three-generation selfing on the F0-generation wheat, performing excellent individual-plant selection toobtain excellent F3-generation wheat single plants, performing threshing on the excellent F3-generation wheat single plants to obtain F4-generation wheat seeds, and performing breeding through the F4-generation wheat seeds. According to the breeding method of drought-resistant wheat disclosed by the invention, the concept of a grain weight drought-resistant index is introduced from a grain weightcomprehensive screening and judging angle under two processing environments, and can be directly applied to breeding of wheat varieties; the screening index is succinct and clear, breeding of wheat drought-resistant varieties
