Summary:The origin, agronomic characteristics, and root productivity of cassava cv. Mae Joana (IM-175) and Zolhudinha (IM-158) are given; the performance of these root rot-resistant cv. was outstanding throughout 9 trials carried out with 258 other cv. to determine appropriate cv. for the varzea area of the state of Amazonas, Brazil.
