Abstract: In order to understand the current status of quinoa quality in the Qaidam Basin.The contents of moisture,ash,starch,fat,crude fiber,total sugar,protein,β-glucan,trace elements and amino acids of 12 quinoa varieties (lines) planted in Dulan area were tested and systematically analyzed by means of multivariate statistical analysis method. The results showed that under the common influence of genetics and environment,there was a significant correlation between trace elements in the same variety (line); and the content of trace elements in quinoa varieties (line) varied greatly.The differences in moisture,fat,protein and amino acid contents were small.The results of principal component analysis showed that when building the model,the content of starch,fat and total sugar should be positively selected,and moisture and protein should be negatively selected. After comprehensive scoring,7 quinoa varieties (line) suitable for planting in the Qaidam Basin(Dulan area) were found. The suitability was:rell > Tianma HX > QLM01 > 614915HX > 1591 > Qingli No.1 > Xining Quinoa; Gongza No.3,Gongza No.4,Gongza No.5,Gongza No.6 and Sanjiang No.2 were not suitable for cultivation in Dulan area. Cluster analysis results showed that 12 quinoa varieties (line) could be clustered into 3 categories,the first category was not suitable for planting in Dulan area,including Gongza No.3,Gongza No.4,Gongza No.5,Gongza No.6; The second category of nutritional quality was in the middle,including Tianma HX,QLM01,614915HX,1591,Qingli No.1,Xining Quinoa,Sanjiang No.2,and could be selectively planted in Dulan according to the actual situation; The third category had only rell strain,which was the most suitable for planted in the Dulan area. Comprehensive analysis of trace elements and amino acid content showed that QML01 and 1591 strains were the best comprehensive characters.
