Yam leaves were collected during surveys of major yam producing agro-ecological zones (AEZs) in Ghana (n = 628) and Togo (n = 218) respectively, in 2005. Leaf tissues were tested for Cucumber mosaic virus (CMV), Dioscorea mottle virus (DMoV), Yam mild mosaic virus (YMMV), Yam mosaic virus (YMV) a...
The project Poverty Alleviation and Enhanced Food Availability in West Africa through Improved Yam Technologies proposed to improve yam production in five West African countries (Nigeria, Bénin, Togo, Ghana, Côte d’Ivoire) during the period from 2000 to 2003. A recognized need for productive, sta...
The effects of 0.2% aqueous solution of colchicine on the survival rate and morphological features of five accessions of Dioscorea alata were investigated. Sprouting buds of two month old plants were treated with 0.2% colchicine and their performances were monitored until maturity. Survival of bu...
In variety development, sensory evaluation is not only the most important hurdle after all the necessary agronomic characteristics have been developed but also a major determinant of acceptability of the variety, as well as a major determinant in the subsequent adoption and use of the variety. Ei...
To be sustainable, production in the traditional yam cropping system, faced with declining soil fertility, could benefit from yam–arbuscular mycorrhizal (AM) symbiosis, which can improve nutrient uptake, disease resistance, and drought tolerance in plants. However, only limited information exists...
Millions of people around the world, particularly in West Africa, depend on yam for food and income, however global yam production has been fluctuating since 2007. Virus infections contribute to yam yield losses and the occurrence of mixed virus infections is potentially catastrophic. Planting of...
This study investigated the impact of processing on retention of iron and zinc in D. rotundata. Fresh tubers were processed into boiled yam and yam flour and analyzed for zinc, iron, and physicochemical properties. Percent true retention (%TR) was assessed using paired samples and a formula that ...
This study was carried out in order to compare pasting behavior and functional characteristics of flours and starches from ten varieties of water yam (D. alata). Differences were established among the arieties in the functional and physical properties of the starches and flours, incl...
Cette étude a été effectuée afin de comparer le comportement de coller et les caractéristiques fonctionnelles des farines et des amidons de dix variétés d’igname (D. alata). Des différences ont été établies parmi les variétés examinées dans les propriétés fonctionnelles et physiques de leurs amid...
