Abstract: To select fresh waxy maize lines with excellent ear appearance quality and rich nutritional components，a randomized block design was used to comparatively analyze the ear characteristics and grain nutritional components of 8 waxy maize lines. The results showed that there were significant differences in kernel weight， fresh 100-grain weight， cob weight，ear length，ear diameter，bald tip length，row number of ear，kernel number of row，axis diameter，vitamin C content，vitamin E content，and vitamin B6 content among the 8 waxy maize lines. The variation coefficient of bald tip length was the largest among ear characteristics，reaching 73. 2%. And the variation coefficient of vitamin E content was the largest among nutrient composition，reaching 99. 03%. The correlation analysis showed that the content of vitamin E was an extremly significant pastive correlation between vitamin E content and vitamin B₆ Content；there was a significant positive correlation between soluble sugar content and the fresh 100-grain weight；the spike length and the number of rows per ear were positively correlated with the weight of the spike axis significantly；the ear diameter was positively correlated with the grain number per row and the grain weight per ear extremly significantly；there was a significant negative correlation between the bald tip length and the fresh 100-grain weight；the grain weight per ear was positively correlated with the grain number per row extremly significantly. Cluster analysis showed that the lines with high comprehensive nutritional quality included Jingcainuo 2，Chengnuo 8，Fengnuo 1，and Jingnuo 832，which provided theoretical support for selecting glutinous corn varieties with rich nutritional components in production.
