Abstract:: Comparison of salt-tolerance for 20 kinds of precious chrysanthemum were studied through soilless cultivation method.The results showed that when NaCl concentration was 0.6 mol/L in nutrient solution,salt tolerance screening of plants from precious chrysanthemum could be achieved effectively and rapidly by salt injury index of plant.Clustering analysis showed that salt tolerance of 20 taxa be divided into extremely strong，strong,medium,weak，extremely weak respectively.‘Huangsongzhen’ were extremely strong salt-tolerance，five taxa represented by ‘Ziyun’ and ‘Qianxiuyinzhen’ were strong salt-tolerance，nine taxa represented by ‘Liandanlu’ were medium salt-tolerance，three taxa represented by ‘Qiushuifurong’ were weak salt-tolerance，two taxa represented by ‘Caixia’ were extremely weak salt-tolerance.
