Aighewi, B.A.Maroya, N.Mignouna, Djana B.[Key for a profitable and sustainable seed yam business enterprise: business plan and market development with record keeping for seed yam farmers]Key for a profitable and sustainable seed yam business enterprise: business plan and market development with record keeping for seed yam farmers

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...


Balogun, M.Maroya, N.Augusto, J.Ajayi, A.Kumar, P.L.Aighewi, B.A.Asiedu, Robert[Relative efficiency of positive selection and tissue culture for generating pathogen-free planting materials of yam (Dioscorea spp.)]Relative efficiency of positive selection and tissue culture for generating pathogen-free planting materials of yam (Dioscorea spp.)

Yam production is constrained by scarcity of clean seed, pests, diseases and low soil fertility in the informal seed system, which is still operational, causing up to 90% yield losses. Although meristem culture can be effective for producing healthy seed yam, its use is limited by slow rate of re...


Balogun, M.Maroya, N.Asiedu, Robert[Status and prospects for improving yam seed systems using temporary immersion bioreactors]Status and prospects for improving yam seed systems using temporary immersion bioreactors

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...
