Method for quickly creating novel peanut germplasm

The invention discloses a method for quickly creating novel peanut germplasm. The method comprises the following steps: selecting a peanut variety with relatively good disease resistance, adaptability and pod and seed kernel traits so as to improve excellent characteristics of the variety through mutagenesis, and soaking seeds by using distilled water; soaking the seeds in an EMS phosphate buffer solution, treating in running water, and airing; performing single-grain sowing, and performing single-plant harvesting at autumn; continuing single-grain and single-row sowing through off-season breeding or in the second season, harvesting single plant offsprings, and eliminating single plants of which the number of pods is smaller than; performing quality detection on the single plants by using a near-infrared instrument, and retaining variant test materials with outstanding quality characteristics in aspects of crude fat, crude protein, high oleic acid and the like; performing secondary mutagenesis on the seeds: m
