Carrot firmness (FIR) is often determined using difficult and time consuming laboratory tests, but it may be more appropriate and economical to develop a method which uses easily available and known quality characteristics of carrot such as water content (WC) and total soluble solids (TSS). In this study, typical two variables linear regression model for predicting FIR of Nantes carrot based on WC and TSS of carrot was suggested. The statistical results of the study indicated that in order to predict carrot FIR based on WC and TSS of carrot, the two variables linear regression model FIR = -2805.8 + 64.9 WC + 36.4 TSS with R 2 = 0.84 can be strongly recommended.
