Cassava mosaic disease (CMD) is the most-important disease of cassava (Manihot esculenta) in Africa, and is a potential threat to Latin American (LA) cassava production. Although this viral disease is still unknown in LA, its vector – the whitefly – has recently been found. The disease is best co...


Akano, A.O.Dixon, Alfred G.O.Mba, CBarrera Sabogal, EFregene, Martin A.[Genetic mapping of a dominant gene conferring resistance to cassava mosaic disease]Genetic mapping of a dominant gene conferring resistance to cassava mosaic disease

Cassava (Manihot esculenta) is a major food staple for nearly 600 million people in Africa, Asia, and Latin America. Major losses in yield result from biotic and abiotic stresses that include diseases such as Cassava Mosaic Disease (CMD) and Cassava Bacterial Blight (CBB), drought, and acid soils...


Anderson, J.W.Delseny, MFregene, Martin A.Jorge, VMba, CLópez, C.E.Restrepo, S.Soto Suárez, M.Piegu, BVerdier, ValérieCooke, RGTohme, Joseph M.Horvat, DP[An EST resource for cassava and other species of Euphorbiaceae]An EST resource for cassava and other species of Euphorbiaceae

The gene pools for breeding cassava (Manihot esculenta Crantz) in Africa currently contain only a fraction of the existing genetic variation found in Latin America where the crop originates. Our research aimed to broaden the genetic base in Africa by introducing Latin American (LA) germplasm. The...

Puentes, YJBarrera Sabogal, ELadino Franco, YJLópez, D.Chavarriaga Aguirre, PaulMba, CFregene, Martin A.[Development of waxy starch cassava varieties via the anti-sense mediated silencing of the granule bound starch synthase I (GBSS I)]Development of waxy starch cassava varieties via the anti-sense mediated silencing of the granule bound starch synthase I (GBSS I)

Breeding goals of yield increases, root quality improvement, and disease resistance in cassava are considerably slowed down by biological characteristics of the crop, which includes a long growth cycle, a heterozygous genetic background and a poor knowledge of the organization of crop diversity. ...
