The invention discloses a screening method for coix drought resistance indexes, and belongs to the technical field of agricultural production. The method includes the steps of (1) germplasm cultivation and planting of test coix; (2) determination of the relative drought resistance indexes; (3) principal component analysis; (4) gradual regression analysis. The screening method is close to the practice of agricultural production, has reliable results, and can solve the problems that the existing screening method for the coix drought resistance indexes is confused and the screened indexes are inconsistent, thereby providing a reliable, simple, economical, applicable and standard drought resistance index screening technology system for coix breeding workers; meanwhile, the screened indexes can comprehensively reflect the comprehensive drought resistance of the coix, and can be effectively applied to the identification of drought resistance of the coix. 本发明公开了种薏苡抗旱指标的筛选方法，属农业生产技术领域，该方法包括以下步骤：（1）供试薏苡种质培养与种植；（2）抗旱相关
