Ceballos, H.Dufour, D.L.Sánchez, T.Morante, NRolland-Sabaté, AgnèsHershey, Clair H.[Potential of the small-granule cassava starch mutation for the bioethanol industry]Potential of the small-granule cassava starch mutation for the bioethanol industry

Functional properties of normal and waxy starches from maize, rice, potato, and cassava as well as the modified waxy maize starch COLFLO 67 were compared. The main objective of this study is to position the recently discovered spontaneous mutation for amylose-free cassava starch in relation to th...


Sánchez, T.Dufour, D.L.Moreno, I.X.Ceballos, H.[Comparison of pasting and gel stabilities of waxy and normal starches from potato, maize, and rice with those of a novel waxy cassava starch under thermal, chemical, and mechanical stress]Comparison of pasting and gel stabilities of waxy and normal starches from potato, maize, and rice with those of a novel waxy cassava starch under thermal, chemical, and mechanical stress

Cassava roots are the most important commercial product from this crop. Roots have two major components: the starchy parenchyma and the peel with higher amount of fibre and cyanogenic glucosides. In this study, a sample of 64 clones grown in replicated trials in five locations were evaluated for ...


Pérez, J.C.Lenis, Jorge I.Calle, FMorante, NSánchez, T.Debouck, Daniel G.Ceballos, H.[Genetic variability of root peel thickness and its influence in extractacle starch from cassava (manihot esculenta Crantz) roots]Genetic variability of root peel thickness and its influence in extractacle starch from cassava (manihot esculenta Crantz) roots

Mapuey tubers in Venezuela are staple food for indigenous peoples from the Caribbean coast and Amazon regions. Noticeable differences between genotypes of yam starches were observed. Granules were large, triangular, or shell-shaped with monomodal particle size distribution between 24.5 and 35.5...

Cassava (Manihot esculenta Crantz) is one of the most important sources of starch in the tropics. There is limited and contradictory information regarding cassava starch characteristics. The International Center for Tropical Agriculture (CIAT) holds in trust FAO's cassava germplasm collection. St...

Ceballos, H.Fregene, Martin A.Pérez Velásquez, Juan CarlosCalle, FJaramillo O, GMorante, NSánchez, T.Chávez, Alba L.Moreno A, IX[Production and identification of high-value cassava clones]Production and identification of high-value cassava clones

Few natural waxy starches are offered to the industry demand. Therefore, the morphological, physical, and chemical characteristics of “Mapuey” waxy starch were assessed. Amylose contents of starches isolated from Dioscorea trifida L. (“Mapuey”) landraces cultivated in the Amazons of Venezuela wer...

Rolland-Sabaté, AgnèsSánchez, T.Buleon, AColonna, PaulCeballos, H.Zhao, SSZhang, P.Dufour, D.L.[Molecular and supra-molecular structure of waxy starches developed from cassava (Manihot esculenta Crantz)]Molecular and supra-molecular structure of waxy starches developed from cassava (Manihot esculenta Crantz)

One of the objectives of the cassava-breeding project at CIAT is the identification of clones with special root quality characteristics. A large number of self-pollinations have been made in search of useful recessive traits. During 2006 harvests an S1 plant produced roots that stained brownish-r...
