Detopping hastened the appearance of mosaic symptoms in shoots of cassava cuttings infected with African cassava mosaic virus (ACMV). The degree of plant recovery from severe mosaic after each detopping was the basis for evaluation of ACMV tolerance. In field‐screening, detopping of cassava shoots infected with ACMV is recommended for selection of tolerance to the virus. One detopping of ACMV‐infected shoots was sufficient to analyze tolerance level reliably. Out of 521 lines only one was found tobe tolerant, while 144 lines were found to be moderately tolerant. These included the lines ‘Gimbi MA 235’, (02945S × 3119)S MA 219, and ‘Kadanga Malombe’ previously described as resistant to ACMV.
