Iron and zinc contents in roots of 72 cassava landraces selected for total carotenoids in roots were quantified. A group of 172 hybrids of family 2003, 136 hybrids of family 2004, and 40 hybrids of family 2005, all with yellow roots were also evaluated. Contents for iron in landraces ranged from 0 to 56.5 mg.Kg-¹ with an average of 9.17 mg.Kg-¹. In the family 2003, the average content was 8.2 mg.Kg-¹ with values ranging from 0 to 51.1 mg.kh-¹. In the family 2004, the average content was 13.1 mg.Kg-¹ with values ranging from 1.0 to 77.5 mg.Kg-¹. In the family 2005, the average content was 23.80 mg.Kg-¹ with values ranging from 20.54 to 30.65 mg.Kg-¹. The zinc contents of the landrecess ranged from 0 to 26.2 mg.Kg-¹ with an average of 4.14 mg.Kg-¹. In the family 2003, zinc content ranged from 0 to 34.1 mg.Kg-¹, with an average of 5.2 mg.Kg-¹. In the family 2004, the values ranged from 0.5 to 87.1 mg.Kg-¹, with an average of 12.50 mg.Kg-¹. And, in the family 2005, zinc content ranged from 1,97 to 34,38 mg Kg-¹, with an average of 7,94 mg.Kg-¹.1 aOLIVEIRA, L.1 aSANTOS, V.1 aCEBALLOS, H.1 aNUTTI, M.1 aCARVALHO, J.
