Abstract：In this study, leaf color parameters of 19 cultivars of Brassica campestris L．ssp．chinensis（L.）Makino（including 3 variants e. g. var. communis Tsen et Lee., var. rosularis Tsen et Lee., and var. taitsai Hort）were determined using a colorimeter and a chlorometer. Correlation and clustering analysis were carried out based on these data. The results showed that significant differences in chlorophyll content and leaf color parameters were found for the tested cultivars. Color parameters including h and C were correlated with content of chlorophyll. Based on the results of clustering analysis, the 19 Brassica campestris L. ssp. chinensis（L.）Makino cultivars were divided into 2 groups with one had light leaf colors, and the other had dark leaf colors. Cvs.‘Lvxiu’,‘PAK’,‘Aijiaohuang’,‘Tadiwu No.3’and‘Jingpintadiwu’were very similar to Japanese cvs.‘Xiadi’,‘Huaguan’, and‘Dongshangwei. The advantages of this method were easy operating, cost and time-saving, and harmless to leaves.
