In this paper, 8 varieties of "2 K5" "Q13-7" "Tuhuangli" "Q13-13" "Huangli" "YY6" "SCI" and "Hongli" were used as research materials to study the salinity tolerance of different quinoa strains during germination. The concentration gradient of the mixed salt-alkali solution was set as 0, 25, 50, 100, 150 mmol/L, respectively. The number of germination, root length and bud length of each strain were counted, and the germination rate and germination index were calculated. The results showed that the indexes such as bud length, germination rate and vigor index all showed an overall trend of increasing in low saline-alkali treatment and decreasing in high saline-alkali treatment, and the germination time was delayed with the increase of saline-alkali stress degree. The comprehensive evaluation by membership function method showed that quinoa "2 K5" and "Q13-7" had better tolerance to mixed saline-alkali stress.
