International Center for Tropical Agriculture[Breeding for insect and other arthropods resistance and development of alternative methods for their control: Output 10]Breeding for insect and other arthropods resistance and development of alternative methods for their control: Output 10

CIAT systematically evaluates all germplasm accessions in diverse sites in Colombia, to obtain a broad characterization of adaptation to different soils and climates, resistance to many pests and diseases, and quality traits. The information is used primarily to select parents which can potential...

Nine cassava (Manihot esculenta) genotypes were grown for three years (1992-1993, 1993-1994 and 1994-1995) in three agro-ecological zones in Nigeria to study their reaction to cassava anthracnose disease (CAD), caused by Colletotrichum gloeosporioides, investigate genotype x environment (G x E) i...

Neuf génotypes de manioc (Manihot esculenta) étaient cultivés pour trois années (1992–1993, 1993–1994 et 1994–19995) dans trois zones agro écologiques au Nigeria en vue d\'étudier leur réaction à la maladie d\'anthracnose du manioc (CAD), causée par les Colletotrichum gloeosporioides, examiner le...

Cassava germplasm development at CIAT is centered on the development of improved gene pools for specific edapho-climatic zones with importance for cassava production. The most relevant ecosystems are the semi-and and sub-humid tropics, for which the majority of efforts are devoted. The main selec...


International Center for Tropical Agriculture[Cassava Breeding Trials - Edaphoclimatic Zone 1: Lowland Tropics; Long drought; Low to Medium Precipitation]Cassava Breeding Trials - Edaphoclimatic Zone 1: Lowland Tropics; Long drought; Low to Medium Precipitation

Cassava is a key food security staple and a competitive feedstock for multiple industrial processes and end uses. Farmers grow hybrids which are reproduced vegetatively. Several programs have used the same breeding scheme for the last 40 years. Significant progress has been made, particularly wit...


Ceballos, H.Hershey, Clair H.[Cassava (Manihot esculenta Crantz)]Cassava (Manihot esculenta Crantz)

This study intended to develop and/or adopt the best cryopresentation protocol for the African cassava germplasm. Eleven protocols were investigated. One protocol focused on the tolerance of pregrowth meristems to DMSO (Dimethyl sulphoxide). The other 10 were cryopresentation protocols and were e...

Some 96 accessions of cassava (Manihot esculenta) were evaluted for genetic diversity using random amplified polymorphic DNA (RAPD) primers. Ten out of 80 Primers were considered highly informative and were used to fingerprint all of the accessions. Amplification of genomic DNA with the primers r...
