Yam (Dioscorea spp.) is a major food of cultural, economic and nutritional importance in Nigeria and throughout West Africa. In this sub-region, white yam (Dioscorea rotundata) is the most dominant and important species. This study is aimed at characterizing high yielding yam varieties of this sp...

Accurate and timely detection is vital for mitigation of tuber yield losses resulting from yam mosaic virus (YMV) infection on yam, a major food security crop in West Africa. The observation, from our previous studies, that the triple antibody sandwich enzyme-linked immunosorbent assay (TAS-ELISA...

Greater yam (Dioscorea alata L.), belonging to the family Dioscoreaceae, is a staple food crop of the tropics. It is cultivated for its edible, nutritious, underground tubers. Its productivity declined due to anthracnose disease. There was no sequence information for yam in the public database. T...

Yams (Dioscorea spp.) constitute a staple food crop for over 100 million people in the humid and subhumid tropics. They are polyploid and vegetatively propagated. The Guinea yams, Dioscorea rotundata and D. cayenensis, are the most important yams in West and Central Africa where they are indigeno...

A collection of 89 water yam (Dioscorea alata L.) accessions from Benin, Congo, Côte d’Ivoire, Equatorial Guinea, Gabon, Ghana, Nigeria, Sierra Leone and Togo was assessed for genetic diversity using thirteen microsatellite loci. These 89 are some of the D. alata accessions conserved by the Inte...

This paper discusses the strategic use of existing genetic diversity in addressing the constraints faced by yam (Dioscorea sp.) production in Bénin, including pest and disease pressure, poor soil and changing climate. Participatory strategies that have been developed to preserve their diversity i...

Seed tuber production of Dioscorea rotundata using the minisett technique was tested on-farm and on-station in different agro-ecological zones in Nigeria. A lower sprouting rate of minisetts was observed in the southern Guinea savanna than in the tropical forest zone. Sprouting and tuber yield in...
