The invention discloses a cultivation method of a wheat preharvest-sprouting-resistance material. The cultivation method comprises the steps of in the first ten-day period and the middle ten-day period of October, culturing wheat seeds for 15 days with a special culture solution prepared from wild oat DNA, and when two leaves and 3-5 roots grow on each seedling, transplanting the seedlings as 0-generation seedlings to a field; In June of the second year, completely harvesting 0-generation seeds, and dibbling all single seeds in early October to form the first generation; harvesting and bundling first-generation plants in the next year; putting the bundled first-generation plants into a dark room, spraying water to wet ears thoroughly, performing covering with a plastic film to preserve moisture, accelerating germination for 15 days, performing baking, performing drying in the sun, performing threshing, floating the seeds with water, eliminating the germinated seeds floating on the water, reserving the non-germinated seeds sinking to the water bottom, and performing quick drying in the sun for second-generation seeding; performing harvesting and threshing at the seventh generation, performing sowing no less than 10,000 plants in single hole and single grain in the field in the middle ten-day period of June, and performing simultaneous sowing contrast; always keeping soil moist after sowing; only reserving and numbering the seedlings which emerge later than the control seedlings, recording the seedling emergence date, transplanting the seedlings into nutrition pots when 3-4 leaves exist, in a semi-shade shed, spraying 0.5% paclobutrazol, performing root irrigation and performing oversummering; and performing transplanting in the first ten-day period of October, and performing pre-harvest-sprouting-resistance identification in the next year. High pre-harvest-sprouting-resistance materials can be selected.
