Cassava (Manihot esculenta Crantz) is the second most important food crop after rice, the staple in Sierra Leone; it is also the most important root and tuber crop. It is followed by sweet potato (Ipomoea batatas L.), yam (Dioscorea spp.), which forms part of the traditional farming system and ha...

Twelve cassava (Manihot esculenta Crantz) genotypes were planted under natural field conditions for two different cropping seasons (wet and dry), in 1992 and 1993 at the research farm of the International Institute of Tropical Agriculture (IITA), Ibadan, Nigeria. The trial studied the effect of p...

The concentration of African cassava mosaic virus (ACMV) was assessed by enzyme-linked immunosorbent assay in relation to symptom severity among resistant, moderately resistant and susceptible cassava genotypes. Resistant genotype NR 8083 had significantly lower symptom severity scores (P < 0·05)...

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...

Thirty-one improved cultivars and five Nigerian landraces of cassava were assessed at genomic DNA level with 16 SSR primers for genetic diversity study. The minimum number of SSR primers that could readily be used for identification of the 36 cassava genotypes was also determined. For the genetic...
