Fifty-three cassava lines were selected from breeding populations at the International Institute of Tropical Agriculture (IITA), Ibadan, Nigeria and screened in vitro for resistance to cassava anthracnose disease (CAD). The in vitro inoculation of stem cuttings with the fungus Colletotrichum gloe...

Forty-seven cultivars of cassava in IITA's trials were screened for their reaction to infection by Colletotrichum gloesporiodes f. sp. manihotis in the field. The following parameters were observed: (a) distance of first canker from the soil, (b) total number of cankers per plant, (c) size of can...
