Abstract Correlation analysis were conducted on 14 tomato（Lycopersicon esculentum Mill.）quantitative traits and lycopene content by using DPS software.The results showed that the lycopene content is very significantly positively correlated with single inflorescence flower numbers,single inflorescence fruit numbers and soluble solids content,but very significantly negatively correlated with size of cordy area around pedicel scar,pedicel length and single fruit weight.The lycopene content is significantly positively correlated with fruit shape index,but significantly negatively correlated with fruit firmness,flesh thickness,longitudinal diameter fruit.
