Gains in maize genetic improvement in Eastern and Southern Africa : I. CIMMYT hybrid breeding pipeline
Monitoring of genetic gain in crop genetic improvement programs is necessary to measure the efficiency of the program. Periodic measurement of genetic gain also allows the efficiency of new technologies incorporated into ...
Successful community-based seed production strategies
Designed to address the issues that limit the access of small-scale farmers in sub-Saharan Africa to quality, affordable seed of the crops on which they depend for food security and livelihoods, this collection of articles ...
Grain yield performance and flowering synchrony of CIMMYT’s tropical maize (Zea mays L.) parental inbred lines and single crosses
Maize production constraints in sub-Saharan Africa (SSA) are being addressed by CIMMYT and partners through an array of projects, focusing on developing and evaluating parental inbred lines and single-crosses as well as ...
Climate change and food security in the developing world: Potential of maize and wheat research to expand options for adaptation and mitigation
Maize and wheat are two of the most important food crops worldwide. Together with rice, they provide 30% of the food calories to 4.5 billion people in almost 100 developing countries. Predictions suggest that climate change ...
Breeding for low input conditions and consequences for participatory plant breeding: examples from tropical maize and wheat
Participatory plant breeding (PPB) has been suggested as an effective alternative to formal plant breeding (FPB) as a breeding strategy for achieving productivity gains under low input conditions. With genetic progress ...
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 ...
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 ...
Combining ability, heterosis and genetic diversity in tropical maize (Zea mays L.) under stress and non-stress conditions
Drought and low soil fertility are considered the most important abiotic stresses limiting maize production in sub-Saharan Africa. Knowledge of the combining ability and diversity of inbred lines with tolerance to the two ...
