Highlights are presented on the status of knowledge about cassava mosaic disease (CMD) and its causal agents in Nigeria. The disease occurs in all the agroecologies where cassava is grown, from the humid forest in the south to the semiarid and arid agroecologies in the north. The severity is gene...

In a study to map out the genes confering resistanceto African cassava msaic disease (ACMD), a cost-effective protocol for zygotic embryo culture developed at the International Institute of Tropical Agriculture(IITA) using 1/2 strenght Murashige and Skoog's basal media, was employed to germinatet...

The aim of the Integrated Cassava Project (ICP) of the International Institute of Tropical Agriculture was to pre-emptively manage the cassava mosaic disease (CMD) to avert an imminent and increasing possible threat of the Ugandan strain of the CMD virus of the pathogen from doing damage to the N...

Cassava mosaic disease (CMD) caused by a group of begomoviruses and transmitted by whitefly vector is a serious disease in all the cassava-growing areas of Africa. Field evaluation with replication was conducted in 2003 and 2004 in three agroecologies in Nigeria to study the response of 40 cassav...

Large-scale screening of cassava, Manihot esculenta Crantz, genotypes for resistance to infestation by whitefly Bemisia tabaci Gennadius, the vector of cassava mosaic geminiviruses, is limited. A range of new cassava elite clones were therefore assessed for the whitefly infestation in the 1999/20...

A study was conducted to determine the extent of genetic diversity among African cassava (Manihot esculenta Crantz) accessions resistant to the cassava mosaic virus disease (CMD), using simple sequence repeat (SSR) markers. The accessions included a breeding stock (clone 58308), five improved lin...
