White Guinea yam ( Dioscorea rotundata Poir.) is an important staple to millions of people in West Africa. Obtaining good quality planting material for yam cultivation is a major challenge. Multiplication ratios are low, and seed tubers are prone to contamination with pests and pathogens in the t...

EFFORTS to improve the yam, D. rotundata, through hybridisation have been frustrated by the low rate of flowering, the very low rate of fruit setting and poor seed germination1–3. These constraints have confined the availability of genetic resources for selection to the small number of cultivars ...

Potyviruses (genus Potyvirus; family Potyviridae) are widely distributed and represent one of the most economically important genera of plant viruses. Therefore, their accurate detection is a key factor in developing efficient control strategies. However, this can sometimes be problematic particu...

Dried yam (Dioscorea spp.) chips are widely consumed in Bénin but are often attacked by molds. Invasion of food by Aspergillus flavus may lead to aflatoxin contamination. We report here the result of a survey on the sanitary quality of dried yam chips in Bénin. During July and August 2000, 50 dri...

To determine whether or not FT-IR spectroscopy could be used for taxonomic and metabolic discriminationof African yam lines, tuber samples from African and Asian yam species were subjected to FT-IR.Most remarkable spectral differences between African and Asian yams were found in the 1750–1700 cm ...

Potato (Solanum tuberosum) production in Africa is rapidly expanding and becoming increasingly important. As its geographical production range broadens, so does its potential to host new pests and diseases. Following the discovery that potato can be affected by Scutellonema bradys, further studie...
