Abstract：The main phenotypic traits of 10 new materials of spring cabbage were analyzed and studied,aiming to provide theoretical reference for selection and extension of spring cabbage in north central nine provinces.Variation analysis showed that the new materials still had innovation potential.The 10 materials were classified into 3 categories by cluster analysis,and the characteristics of each category were given by descriptive statistical analysis.By using partial correlation analysis,stepwise regression analysis and path analysis,the influence factors of cabbage single head weight were studied from various angles.The results showed that the main phenotypic trait promoting single head weight was head diameter,and the second was head height;the main phenotypic traits suppressing single head weight were number of outer leaves and plant breadth.The reliability of the optimal regression equation for predicting single head weight was 79.2％,which showed that other important factors affecting single head weight were not included in the experimental study still.
