Review demonstrates massive import deficits and abiotic-biotic stresses in Sub-Saharan African wheat systems, highlighting the need for climate-resilient breeding programs.

Key Points

To review the status, supply chain dynamics, and agronomic constraints of wheat production in Sub-Saharan Africa while evaluating genetic improvement approaches led by national and international breeding programs.
Synthesized regional agricultural literature, demand-supply trade data, and production metrics across Sub-Saharan Africa.
Assessed modern breeding approaches, including mega-environment targeting, shuttle breeding, doubled haploids, marker-assisted selection, and key location phenotyping implemented by international research centers.
Regional wheat consumption reached 25 million tons in 2013, with domestic production yielding only 7.3 million tons across 2.9 million hectares (average yield of 2.0 t/ha), necessitating 17.5 million tons in imports costing USD 6 billion.
Wheat yields remain constrained by escalating abiotic stresses (heat, drought) and biotic pathogens (yellow rust, stem rust, septoria, fusarium), coupled with high production costs and low technology adoption rates.
The majority of commercial cultivars grown in the region derive from collaborative partnerships between National Agricultural Research Systems and international centers (CIMMYT and ICARDA) focused on stress resilience.
