Cassava bacterial blight (CBB), caused by Xanthomonas axonopodis pv. manihotis (Xam), is a major disease of cassava (Manihot esculenta Crantz) in Africa and South America. Planting resistant varieties is the preferred method of disease control. Recent genetic mapping of an F1 cross (TMS 30572 × C...

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. ...

CBN is an informal forum for cassava biotechnologists, collaborating research and development specialists, and cassava research users. CBN`s research goals are genetic and processing improvements for cassava. Its development goal is to encourage interdisciplinary research in national programs of ...

The genetic resources available for cassava improvement include advanced breeding lines, collected landraces and the crops`s wild relatives. Information about the structure of these gene pools is important in the development of sound germplasm conservation and use strategies. RAPD markers have be...

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 purpose of this study was to compare the in vitro iron availability from diverse iron biofortified International Potato Center (CIP) potato clones grown in the Peruvian Andes and, thereby, to provide key information to breeders seeking to increase bioavailable iron from potato.
