The color value units, number of fruit per plant, number of seeds per plant, fruit ball diameter, weight per 100 seeds, yield per plant, petal yield per plant of 69 non-thorn safflower (Carthamus tinctorius L.) germplasm resources were evaluated by correlation analysis and cluster analysis.The results showed that there was large variations among the 69 materials, and the number of fruit ball per plant contributed the most to the yield. Based on analysis of color value units,the safflower germplasm resources were divided into 3 groups .the color value units of safflower were 6.3-14.1, while 14 with high color value units among all resource. Based on cluster analysis on 7 characters,the safflower germplasm resources were divided into 5 groups . The characters of each group were different and the differences were abundant, the groupⅣ were chosen as excellent resources for safflower breeding which have the best overall performance. Safflower breeding resources showed great diversity in color value units and yield characters, but the resources with high value units had small proportion.The comprehensive analysis of color value units and main yield traits established foundation to the effective utilization of safflower germplasm resources and the breeding of new safflower varieties with high color value and high yield..
