Drought-resistant wheat variety breeding method

The invention provides a drought-resistant wheat variety breeding method. The method comprises the following steps of S1, setting two treatment modes of zero watering and twice watering for an F1 generation, performing uniform sowing, planting and harvesting, manually measuring the thousand seed weight, selecting materials with zero-watering thousand seed weights being greater than or equal to 39gand a zero-twice-watering drought-resistant indexes being greater than or equal to 1.1 to enter a step S2; S2, setting one treatment of twice watering for the F2 generation, enabling the F2 generation to fully grow, screening high-yield characters of the F2 generation, and screening out single plants with high yield potential to enter S3; S3, setting two treatments of zero watering and twice watering in the step S3, planting each variety of the materials screened in the step S2 into two plant rows for two kinds of watering treatments, dividing harvested seeds in such a way that zero-wateringseeds F30 are obtained thr
