The unavailability of good quality seed yams (Dioscorea rotundata Poir) is frequently cited to be responsible for the slow rate of growth or decline in yam production. Current production and storage practices, as well as quality of seed yams in 35 villages of Oyo North, Asaba, Lokoja, and Lafia a...

Tuber of most varieties of white Guinea yam, Dioscorea rotundata Poir., produce a single sprout in the proximal region after the break dormancy. The location and pattern of sprout formation on intact tubers of a multiple sprouting variety, Pepa were studied. Only 0.4% of the tubers had a single s...

Yams are staples in West Africa. They are propagated from tubers in an informal seed system. This encourages a build-up of diseases, and necessitates the rapid development of a formal seed system where certified seeds are functional. Although few reports exist on the use of meristem culture to ge...
