Bean common mosaic virus (BCMV) is seed transmitted and the most important virus disease of beans in Africa. A breeding programme was initiated in 1990 in Uganda to develop lines with resistance to necrotic strains that predominate in the continent. Evaluation of field layout on infection level s...

Common bacterial blight (CBB) is the most serious bacterial disease of common bean in Uganda. It causes severe yield losses of up to 62%. Genetic resistance is the most effective option for controlling CBB in smallholder common bean production systems. This study was carried out to determine the ...
