This study was conducted to investigate correlation between external factors of chicory root and chicon fresh weight, whereby, to provide basic information of external yardstick of producing standardized chicon. For correlation between external factors (root diameter, root weight) of chicory root and chicon fresh weight were highly correlated. The relationship between external factors (root diameter, root weight) of chicory root and chicon fresh weight, root diameter was strongly affecting chicon fresh weight due to significant at its regression coefficient (6.06***). In order to verify this correlation, the root diameter (x) of chicory that were 3 different varieties were based on the 4 different root diameter treatments, such as x less-than or equal to 30 mm, 30 less than x less-than or equal to 40 mm, 40 less than x less-than or equal to 50 mm and x greater than 50 mm. The chicon production increased as root diameter increased and the chicon fresh weight, chicon width, and the number of leaves increased as well. Therefore, the measure of root diameter of chicory instead of the internal factors (carbohydrate, and so on.) can be used to predict the chicon fresh weight.
