Abstract Folic acid is one of the ten essential vitamins in the human diet. Red beet (Beta vulgaris L.) is an excellent source of free folic acid among vegetable plants. Thirty-seven F3 families derived from the cross W364 × Nochowski, sixteen F3 families derived from the reciprocal cross, and the two parents were evaluated for free folic acid content (FFAC) in two locations in Wisconsin in 1994. Parental means of FFAC were 3.4 and 8.8 µg g-1 dry wt. for Nochowski and W364, respectively. The range of FFAC in F3 families was from 2.3 to 15.8 µg g-1 dry wt. The genetic variance among F3 families was large. Transgressive segregation for FFAC was observed in the F3 family distribution, suggesting multiple genes control this trait. FFAC means differed at the two locations. Overall means of the reciprocal crosses were significantly different in FFAC at both locations (P 〈 0.05), suggesting reciprocal effects on FFAC in this population. The broad sense heritability for FFAC in this population was estimated as 0.84.
