| Marker-assisted breeding could have a major impact in relieving productivity constraints that cannot as easily or rapidly be relieved by conventional breeding alone. This paper estimates the benefits of using marker-assisted breeding, as compared to conventional breeding alone, in developing cassava varieties resistant to cassava mosaic disease, green mite, whitefly and post-harvest physiological deterioration in Nigeria, Ghana and Uganda. Marker-assisted breeding is estimated to save at least four years in the breeding cycle for varieties resistant to the pests and to result in incremental net benefits over 25 years in the range of $34 to $800 million depending on the country, the particular constraint and various assumptions. Benefits may reach as high... |

| This study addressed the issue of gender and agricultural commercialization among smallholders in Nigeria with ginger as a case study. It focused on the relative or absolute roles, gains and losses by men and women farmers as a result of commercializing small ginger farm. Ginger is a crop grown mainly for cash in Nigeria. Nigerian ginger is known to produce very high quality essential oils mainly oleoresin and gingerol used in confectionery and pharmaceutical industries. Men take decision mostly on ginger production while ginger marketing is more of the women’s job. Women income is devoted to food and children care while men take care of education of the children. There is increased income and improved health facilities to members of the household. There... |
