Moyo, C.Mahungu, N.M.Mkumbira, J.Benesi, I.[Challenges and opportunities for improvement in cassava and sweetpotato seed systems in Southern Africa]Challenges and opportunities for improvement in cassava and sweetpotato seed systems in Southern Africa

Cassava roots contain cyanogenic glucosides. Malawian farmers classify cultivars into two groups based on the perceived danger of eating raw roots that they associate with bitterness. In the vernacular, cultivars that produce roots with bitter taste are called vyakubaba (bitter), whereas those yi...


Chiwona-Karltun, L.Brimer, L.Kalenga Saka, J.D.Mhone, A.R.Mkumbira, J.Johansson, L.Bokanga, M.Mahungu, N.M.Rosling, H.[Bitter taste in cassava roots correlates with cyanogenic glucoside levels]Bitter taste in cassava roots correlates with cyanogenic glucoside levels

Cassava (Manihot esculenta Crantz) and sweetpotato (Ipomoea batatas Lam) are important food and cash crops in Malawi. However, key information regarding varieties grown, sources of planting materials, post-harvest handling, utilisation and tuber yields is lacking. A study was, therefore, conducte...

Le manioc (Manihot esculenta Crantz) et la patate douce (Ipomoea batatas Lam) sont des importants aliments et plantes génératrices de ressources en Malawi. Cependant, l\'information clé concernant les variétés plantées, les sources de matériels de plantation, les manœuvres post-récoltes, l\'utili...

Cassava(Manihot esculenta), a root crop originating in Tropical America, has been called Africa’s food insurance but vital as that is, it has the potential to be much more. Already, cassava provides more than half of the dietary calories for over 200 million people in sub-Saharan Africa (about ha...

Cassava (Manihot esculenta Crantz) is the second most important staple food crop in sub-Saharan Africa, providing up to 285 calories per person per day. Cassava starch is a potentially important industrial material in Malawi. Industries hesitate to use cassava starch because the powder sold by so...

Twenty four arbitrarily selected cassava (Manihot esculenta Crantz) landraces, supplied by the germplasm collections in Kibaha and Ukiriguru research stations of Tanzania, were analysed by two different molecular marker techniques. Genetic distances on the basis of RAPD (random amplified polymorp...

Cassava mosaic disease (CMD) is the major production constraint oncassava (Manihot esculenta) in Angola. Previous reports derived fromsingle samples recorded the presence of African cassava mosaic virus(ACMV) and East African cassava mosaic virus (EACMV) in Angola.Regional CMD ...


Kumar, P.L.Akinbade, S.A.Dixon, Alfred G.O.Mahungu, N.M.Mutunda, M.P.Kiala, D.Legg, J.P.[First report of the occurrence of East African cassava mosaic virusUganda (EACMVUG) in Angola]First report of the occurrence of East African cassava mosaic virusUganda (EACMVUG) in Angola

The major constraints to stable production of cassava in Africa are diseases, insects, mites, weeds, soil and agronomic limitations and socio-economic factors. Of the economic diseases, African cassava mosaic, bacterial blight, and anthracnose are the most important. The green spider mite and cas...

This paper evaluates the impact of a cassava research-for-development program on farm level outcomes.The program was implemented in the Democratic Republic of Congo from 2001 to 2009. We apply pro-pensity score matching, Rosenbaum bounds on treatment effects, Altonji et al. method of selection on...
