A genetic linkage map of cassava has been constructed with 132 RFLPs, 30 RAPDs, 3 microsatellites, and 3 isoenzyme markers segregating from the heterozygous female parent of an intraspecific cross. The F1 cross was made between ‘TMS 30572’ and ‘CM?2177-2’, elite cassava cultivars from Nigeria and...

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. ...

A preliminary linkage map of cassava (Manihot esculenta Crantz) to increase the efficiency of introgression of specific chromosomes or chromosome fragments from exotic cassava germplasm into various genetic backgrounds and localization of genes of interest in cassava improvement schemes has been ...

Random amplified polymorphic DNA (RAPD) analysis was performed on three F1 populations obtained from intraspecific controlled crosses of cassava. Segregation of the RAPD fragments was analyzed to determine if these can serve as genetic markers in cassava for subsequent use in linkage analysis. Se...

The construction of a detailed genetic map of cassava (Manihot esculenta Crantz) will be useful to tag agronomically important trais as well as to isolate and to clone cassava genes in the future. This map will also contribute to the understanding of cassava genomic structure and evolution. As a ...
