Challenges of the maize seed industry in eastern and southern Africa: A compelling case for private-public intervention to promote growth
Following the liberalization and restructuring of the seed sector, the maize seed industry in eastern and southern Africa has witnessed a proliferation of private seed companies. Whereas the total number of registered maize ...
Consumer acceptability of yellow maize products in Zimbabwe
This study analyzes consumers’ awareness of and attitudes towards yellow maize products in Zimbabwe and suggests intervention strategies that will ensure increased production and consumption of the crop, which is ...
Efficiency of managed-stress screening of elite maize hybrids under drought and low-N for yield under rainfed conditions in Southern Africa
Maize (Zea mays L.) yields in southern Africa are low, due largely to drought and low-N stress. Selection of stress-tolerant genotypes by CIMMYT is conducted indirectly under managed stress conditions, although the selection ...
Evaluation of early to medium maturing open pollinated maize varieties in SADC region using GGE biplot based on the SREG model
Analysis of multi-environment trials (METs) of genotypes (G) and genotype × environment (GE) interactions for yield performance across environments, and selection of the best genotypes is an important routine in maize ...
Nonlinear heat effects on African maize as evidenced by historical yield trials
New approaches are needed to accelerate understanding of climate impacts on crop yields, particularly in tropical regions. Past studies have relied mainly on crop-simulation models1, 2 or statistical analyses based on ...
Breeding for improved abiotic stress tolerance in maize adapted to southern Africa
The difficulty of choosing appropriate selection environments has restricted breeding progress for abiotic stress tolerance in highly variable target environments. Genotype-by-environment interactions in southern African ...
