Zusammenfassung: | The invention discloses a method for screening a breeding material capable of resisting enterospora hepatopenaeus character of litopenaeus vannamei. Comprising six screening links of prawn group (family) collection, prawn group (family) anti-EHP phenotypic character test, candidate group (family) EHP artificial simulation infection, candidate group (family) prawn individual first-round screening, candidate group (family) prawn individual second-round screening and candidate group (family) prawn individual third-round screening. According to the method, the key point of screening of the breeding materials is converted into screening of prawn individuals from screening of the population (family), the elimination rate of the individuals in the final population (family) reaches 95% or above, and the screening accuracy of the breeding materials with the EHP resistance is greatly improved.
