Mahuku, George S.Lockhart, B.E.L.Wanjala, B.W.Jones, M.Kimunye, J.N.Stewart, L.R.Cassone, B.J.Sevgan, S.Nyasani, J.O.Kusia, E.Kumar, P.L.Niblett, C.L.Kiggundu, A.Asea, G.Pappu, H.R.Wangai, A.Prasanna, B.M.Redinbaugh, M.G.[Maize Lethal Necrosis (MLN), an emerging threat to maize-based food security in sub-Saharan Africa]Maize Lethal Necrosis (MLN), an emerging threat to maize-based food security in sub-Saharan Africa

In Sub-Saharan Africa, sweetpotato pre-basic seed is multiplied in screenhouses using a sterilized soil substrate. This is expensive and unsustainable. The use of sand substrate with a fertigation system (“sandponics”), is an alternative. The study compared the cost-effectiveness for pre-basic se...

The genetic relationships among 192 superior, high-yielding, and disease-resistant sweetpotato [Ipomoea batatas (L.) Lam] accessions from the Ugandan germplasm collection were analyzed using 10 fluorescent labeled simple sequence repeat (SSR) markers. Relatedness among the genotypes was estimated...

Studies to quantify genetic variation in cassava germplasm, available within the national breeding programmes in Africa, have been limited. Here, we report on the nature and extent of genetic variation that exists within 1401 cassava varieties from seven countries: Tanzania (270 genotypes); Ugand...
