Abstract: Taking 18 commonly cultivated varietes of Chinese chives as the test materials, 6 NaCl concentrations(0,60,120,180,240,and 300 mmol·L^-1) were set up for salt stress treatment.Germination rate, germination potential, germination index, root length, and bud length were used as evaluation indicators.The membership function analysis method was used to comprehensively evaluate the salt tolerance of Chinese chive varieties during seed germination, in order to provide reference for identifying the salt tolerance of different Chinese chive varieties during seed germination and screening for Chinese chive varieties with strong salt tolerance.The results showed that the optimal NaCl concentration for identifying salt tolerance during the germination period of Chinese chive was 120 mmol·L^-1.Based on membership function clustering analysis, the salt tolerance of 18 Chinese chive varieties was categorized into three groups, the Ⅰ group, with the highest salt tolerance, consisted solely of ‘Jiuxing 16’.The Ⅱ group, exhibiting moderate salt tolerance, includes ‘791’ ‘Lyubao’ ‘Hangyan 998’ ‘Pingfeng 1’ ‘Pingjiu 4’ ‘Pengbao’ ‘Jiubao’ ‘Jiuxing 20’ ‘Pingjiu 2’ ‘Jiuxing 18’ ‘Pingfeng 2’ ‘Pingyuan Chunguan’.The Ⅲ group, displaying weak salt tolerance, comprised ‘Pingfeng 6’ ‘Pingfeng 7’ ‘Dongjiuwang’ ‘Pingfeng 8’ ‘Pingfeng 22’.
