Three RFLP maps, as well as several RAPD maps have been developed in common bean (Phaseolus vulgaris L.). In order to align these maps, a core linkage map was established in the recombinant inbred population BAT93×Jalo EEP558 (BJ). This map has a total length of 1226?cM and comprises 563 markers,...

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...


Jorge, VFregene, Martin A.Duque E., Myriam CristinaBonierbale, Merideth W.Tohme, Joseph M.Verdier, Valérie[Genetic mapping of resistance to bacterial blight disease in cassava (Manihot esculenta Crantz)]Genetic mapping of resistance to bacterial blight disease in cassava (Manihot esculenta Crantz)

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...
