Balogun, M.Maroya, N.Taiwo, J.Ossai, C.Ajayi, A.Kumar, P.L.Pelemo, O.Aighewi, B.A.Asiedu, Robert[Clean breeder seed yam tuber production using temporary immersion bioreactors]Clean breeder seed yam tuber production using temporary immersion bioreactors

The Yam Improvement for Income and Food Security in West Africa (YIIFSWA) project was initiated to assess and understand the yam-based systems in order to identify the opportunities of interventions that could potentially help to increase productivity in the region. The project consists of two ph...

Yam production is constrained by the limited availability and high cost of quality seed due to its slow vegetative propagation ratio. Micropropagation using nodal and meristem explants have been used to produce clean plantlets, with a 1:4 multiplication ratio for nodal explants and 1:1 ratio for ...

International Institute of Tropical AgricultureAsiedu, RobertBramel-Cox, P.J.Chikoye, D.Manyong, Victor M.López, K.[R4D Review]R4D Review

Inadequate availability of disease-free planting materials remains a major constraint to yam production. The tissue culture technique has been used to regenerate disease-free plantlets from pre-formed, heattreated meristems followed by micropropagation. This procedure, however, has a low multipli...
