To evaluate and classify the salt-alkali tolerance of 79 Chinese kale samples during the germination stage， this study examined eight indicators including germination potential， germination rate， germination index， shoot fresh weight， vigor index， chlorophyll content， root length， and shoot length under three treatments： control check （ deionized water， pH 6.5）， salt stress （ NaCl ， Na⁺ 240 mmol/L ， pH 6.5）， and salt-alkali stress （NaCl + Na?CO?， Na⁺ 240 mmol/L， pH 9.0）. Principal component analysis， membership function analysis， comprehensive salt-alkali tolerance index D-value， and cluster analysis were conducted. The results showed that， compared with control check ， both salt stress and salt-alkali stress inhibited all germination indicators， with the most significant suppression observed in root length which decreased by 92.08% and 91.49%， respectively， and the coefficient of variation increased by 5.36 and 6.36 times. When comparing saline-alkali stress with salt stress， the proportions of varieties showing significant increases and decreases in different germination indicators varied. For germination potential， 44.30% of varieties showed a significant increase， while 24.05% showed a significant decrease. Meanwhile， 11.39% of varieties showed a significant increase， and 5.06% showed a significant decrease for root length. Based on the cluster analysis of the comprehensive salt-alkali tolerance index D-value， Chinese kale materials were classified into five categories： highly salt （salt-alkali） sensitive type， moderately salt （salt-alkali） sensitive type， salt （salt-alkali） tolerant type， moderately salt （salt-alkali） tolerant type， and highly salt （salt-alkali） tolerant type， with the number of varieties in sequence is 13 （14）， 19 （12）， 21 （27）， 19 （17）， and 7 （9）， respectively. Venn diagram analysis of extreme-type materials identified 12 highly double salt-salt-alkali sensitive types and six highly double salt-salt-alkali tolerant types. A comparison of eight relative indicators of four randomly selected highly double salt-salt-alkali sensitive type and four highly double salt-salt-alkali tolerant type materials showed that， except for relative shoot fresh weight and relative root length， the other six relative indicators of the highly double salt-salt-alkali tolerant type were significantly or extremely significantly higher than those of the highly double salt-salt-alkali sensitive type. The results of this study provide an important resource foundation for the breeding of salt-alkali tolerant Chinese kale varieties and the identification of key stress-resistant genes.
