Study on Comparision of Lycopene Contents Among Watermelon Germplasm Resources

The lycopene content of 44 cultivars and lines of watermelons in center and edge position were determined.The correlation of the lycopene content and flesh color,the soluble solids content were anglicized,in order to provide the basis for quality of watermelon breeding parent matching and high lycopene watermelon breeding.The results showed that red and yellow-fleshed cultivars varied greatly in lycopene content,ranging from 3.687 to 4.039 mg/100gFW in red-fleshed center position,3.473~3.953 mg/100gFW in edge position.Total lycopene content varied from 0.518 to 0.955 mg/100gFW among yellow-fleshed watermelons in center position,from 0.435 to 0.905 mg/100gFW in edge position.The lycopene content in center position had very significant positive correlation with in edge position.Correlation coefficient was 0.987.The lycopene content in center and edge position had very significant positive correlation with the flesh color.Correlation coefficient was 0.8135,0.8044,respectively.The lycopene content in center and edge position had no correlation with the soluble solids content.
