Crop landraces (largely resulting from adaptation and continuous selection by farmers) are more diverse within field populations than modern cultivars (produced by deliberate crossing), yet their distribution has continued to shrink in the past decades. The temporal dynamics of this shrinking is ...

The information in this manual was selected following gaps identified at community level through focus group discussions and household surveys. The guide first describes what food security implies, it then goes on to give basic concepts on nutrition, i.e., types of nutrients, role in the body and...

RNA interference (RNAi) is a natural defense mechanism triggered by double-stranded RNA (dsRNA) for protection of cells against foreign parasitic nucleic acids. The RNase III enzyme Dicer processes dsRNAs into short small interfering RNAs (siRNAs) that degrade the specific mRNA. RNAi has been dem...

Over the past three decades, more than 40 banana cultivars have been introduced in eastern and southern Africa for evaluation and dissemination to smallholder farmers facing banana productivity challenges. This study analyses the seed systems used to avail the genotypes to the target users, discu...

Biotic constraints cause major crop losses and, hence, food insecurity in sub-Saharan Africa. This study documented the popularity, production constraints, pests and diseases, farmers’ perceptions on the severity of biotic constraints and the impact of related crop losses on household food securi...

Xanthomonas wilt (XW) caused by Xanthomonas campestris pv. musacearum (Xcm) is an important constraint to banana production in East and Central Africa. The use of clean planting materials (CPM) for establishing new fields/ re-planting rouged fields/mats is recommended. However, banana is mainly p...

Insects are a major mode of banana Xanthomonas wilt (XW) spread. High insect activity has been blamed for the high XW incidence in ‘Kayinja’ (ABB-genome) dominated banana landscapes across east and central Africa. ‘Kayinja’ male bud nectar composition reportedly contributes to high insect activit...
