Iron (Fe) and Zinc (Zn) concentrations in tuberous roots of twenty-five cassava (Manihot esculenta Crantz) genotypes were determined over 2 years (2004/2005 and 2005/2006) at five locations representing distinct agroecologies in Nigeria. The objectives were to study the magnitude and nature of ge...

The effects of genotype (G), environment (E), and G x E interaction on carotenoid concentration and yield of 25 yellow-fleshed (YF) and three white-fleshed (WF) cassava genotypes were investigated at five locations in Nigeria for two consecutive cropping seasons. The locations represented the maj...

Cassava is an appropriate commodity to feature in Africa’s future economic development. As the crop rapidly changes from a basic foodstuff to a source of income and employment for rural populations, there is a parallel need to increase productivity, marketing opportunities and profitability. This...

Cassava is widely consumed in Africa where malnutrition is rampant; there is, therefore, a major effort to produce micronutrient biofortified cassava. Adoption of such cassava genotypes will largely depend on their agronomic performance, resistance to biotic stresses, and the stability of these t...

Cassava (Manihot esculenta) growing in Uganda during 2001–2002 has been screened for the presence of begomoviruses using PCR-RFLP, cloning full-length genomic components and nucleotide sequence analysis. In contrast with a recent survey in neighbouring Kenya, which identified three distinct strai...

In a bid to increase the number of genotypes reaching farmers, on-farm trials were conducted in 2001/2002 with the aim of increasing the number of genotypes available to farmers to be evaluated for performance, adaptation and acceptability. Twenty improved genotypes were planted in Lira, Nakasong...
