The invention relates to a method for identifying resistance against heterodera glycines. The method comprises the following steps: scissoring the tissue of young part of the soybean vegetative part of the susceptible control variety and the variety to be identified to perform inductive rooting culture; after the transplanted seedling survives, inoculating the seedling with heterodera glycines suspension containing 400 eggs and/or second-stage larvae/mL; continuing culture at 20-30 DEG C; when white cyst appears at the seedling root, separating counting the number of root cyst of the susceptible control variety and the variety to be identified; and defining the disease resistance of the material according to the resistance grading standard. The method provided by the invention has the positive and beneficial effects that: as the genotype is not changed when the vegetative body roots, the resistance of the vegetative body can represent the resistance of the parent material; one part of the vegetative body of the material to be identified replaces the entire plant for identification, and the resistive material can be completely stored; and for the population of segregative generation (for example, F2), 3-5 branches on one individual plant can be fetched for identification so as to realize repeated identification of the segregation population.
