Abstract：Through an adaptability evaluation of 20 Chinese cabbage varieties grown in the open field in the alpine region of Qinghai,this study aims to provide references for the selection and promotion of superior Chinese cabbage varieties in this area.Data on 10 quantitative traits and 9 nutritional indicators of the tested materials were collected and subjected to correlation,principal component,and membership function analyses.The results showed that the agronomic traits of the tested materials exhibited a wide range of variation and diversity.Correlation analysis revealed 9 pairs of traits with extremely significant correlations.In the principal component analysis,the cumulative contribution rate of the first 9 principal components reached 89.46％,and the membership function values ranged from 0.32 to 0.53.Based on compre-hensive principal component evaluation and membership function analysis,Tianqing 75 was found to excel in agronomic traits such as head height,head diameter,untrimmed head mass,and single head mass,while also exhibiting low nitrite content in the leaf midribs.Jiaoyan 5869 performed well in plant spread and single head mass,with high total sugar content in the leaf midribs and high soluble sugar content in the leaves.Gailiang Qingza 3 demonstrated overall excellent quality with no significant weaknesses.Qiuxi showed high water content.In general,the four varieties(Tianqing 75,Jiaoyan 5869,Gailiang Qingza 3,and Qiuxi)have good performance in this study,which can provide a reference for the selection of Chinese cabbage varieties according to different needs in Qinghai region.
