Field evaluation of six cassava genotypes for resistance to root rot disease was compared with three rapid laboratory methods (whole root inoculation, root slice inoculation, and stem inoculation) for resistance screening. Both the field evaluation and the three laboratory methods separated the v...

Pathogenic variation of Botryodiplodia theobromae, the cause of cassava root rot disease in Nigeria, was evaluated with 84 isolates from three different ecological zones and four genetically diverse cassava genotypes using root slice inoculation assay. Significant variation was observed for the a...

Cassava root rot disease is an increasing problem in Africa where yield losses of about 80% have been recorded. We evaluated 290 African landraces and 306 improved genotypes from the germplasm collections of the International Institute of Tropical Agriculture (IITA), for sources of resistance usi...
