On-farm yield gains with Stress-Tolerant Maize in Eastern and Southern Africa
(American Society of Agronomy, 2017)
Maize (Zea mays L.) is the most important staple food in eastern and southern Africa (ESA) with human maize consumption averaging 91 kg capita–1 yr–1. Current maize yield averages 1.2 t ha–1 and is barely suffi cient for ...

Gains in maize genetic improvement in Eastern and Southern Africa: II. CIMMYT open-pollinated variety breeding pipeline
(Crop Science Society of America (CSSA), 2017)
Open-pollinated varieties (OP Vs) still represent a significant proportion of the maize (Zea mays L.) seed system in many countries of sub- Saharan Africa. The International Maize and Wheat Improvement Centre (CIMMYT) has ...

Genomic prediction in a large African maize population
(Crop Science Society of America (CSSA), 2017)
Genomic prediction (GP) combines genomewide marker data with phenotypic data in a training population to predict the genomic estimated breeding values of untested individuals in a relevant testing population. Our objective ...

Genetic diversity among selected elite CIMMYT maize hybrids in East and Southern Africa
(Crop Science Society of America, 2017)
Genetic gain within the CIMMYT Eastern and Southern Africa (ESA) hybrid maize (Zea mays L.) breeding program from 2000 to 2010 was recently estimated at 0.85 to 2.2% yr−1 under various environmental conditions. Over 100 ...
