In this study, 16 F1 hybrids of sugar beet and their parents were used. The roots were analyzed to determine sugar content and levels of non-sugars (potassium, sodium, alfa-amino nitrogen), and these data were then used to calculate the sugar utilization percentage. Correlation analysis was used to determine to what extent the studied traits of the F1 hybrids were connected with those of the parents. Sugar content, sugar utilization percentage, and potassium content of the F1 hybrids were strongly positively correlated with the same traits of the male parent (r0.60), while their correlation with these traits in the female parent was very weak (r0.15). Sodium and alfa-amino nitrogen contents of the F1 hybrids were equally positively, though not too strongly, correlated with the same traits of both parental components (r
