Deployment of resistant varieties is one major approach to controlling cassava bacterial blight (CBB), caused by Xanthomonas axonopodis pv. manihotis (Xam). To understand the genetic determinism of resistance to CBB, the use of reliable parameters measuring resistance is necessary. In order to te...

Rapid-cycling recurrent selection has been implemented to produce cassava varieties that deliver provitamin A carotenoids to human populations that are affected by vitamin A deficiency. Rapid-cycling selection relies on quantification in just one plant per genotype. This study was conducted to a...

A two-year field trial was conducted to study the effects of prolonged water stress on cassava (Manihot esculenta) productivity, and on nutrient uptake and use efficiency. Four contrasting cultivars were supplied with adequate fertilization and watering, except when water was excluded by covering...

Varietal selection is particularly difficult for very heterogeneous environments where farmers have a range of preferences. To address these issues in Rwanda, local bean experts, generally women, are invited to the research station to assess cultivars and to select those they prefer for their plo...

More than 60 accessions of tepary bean (Phaseolus acutifolius) and five cultivars of common bean (P. vulgaris) were evaluated for disease reactions to different races of wilt-causing Fusarium (F. oxysporum f. sp. phaseoli) under glasshouse conditions; 95% of the tepary accessions were resistant. ...
