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...

Cassava mosaic disease (CMD) in Africa is caused by six distinct cassava mosaic viruses (family eminiviridae, genus Begomovirus). Among them, African cassava mosaic virus (ACMV) and East African cassava mosaicCameroon virus (EACMCV) have been reported in CMD-infected cassava plants in Nigeria. Ba...

The identification of superior genotypes and mega-environments on the basis of multiple traits is a key objective of multi-environment trials in cassava (Manihot esculenta Crantz). The objective of this study was to examine the genetic variation and genotype 3 environment interaction (GEI) effect...

Cassava mosaic disease (CMD) caused by African cassava mosaic virus (ACMV) and East African cassava mosaic Cameroon virus (EACMCV) is the major constraint to cassava production in Nigeria. Sequences of the DNA-A component of ACMV and EACMCV isolates from leguminous plant species (Senna occidental...

Cassava mosaic disease (CMD) is a widespread viral disease that causes high yield losses in susceptible genotypes in Sub-Saharan Africa. Effective control of CMD is beneficial and justifiable since cassava is an important source of carbohydrates for over 200 million people in most African countri...

A diagnostic survey was conducted in 2002 and 2003 to determine the status of cassava mosaic disease (CMD) and cassava mosaic begomoviruses in Nigeria and to ascertain if the virulent Ugandan variant of the East African cassava mosaic virus (EACMV-Ug2) is present in the country. The survey was an...
