Abstract: In order to screen more ornamental and suitable for large-scale production of Allium giganteumvarieties,the analytic hierarchy process（AHP）was used to evaluate 23 Allium giganteumvarieties introduced and collected,and the comprehensive evaluation system of Allium giganteum was established by AHP,with 4 criteria layers and 18 index layers established.The results showed that the overall traits were the key factors affecting the evaluation of Allium giganteum,and the more restrictive specific indicators were seedling emergence rate,plant type and leaf color.According to the evaluation system,nine Allium giganteumvarieties with excellent performance were selected out which could be used for application and large-scale production.
