Identification of donors for low-nitrogen stress with maize lethal necrosis (MLN) tolerance for maize breeding in sub-Saharan Africa
After drought, a major challenge to smallholder farmers in sub-Saharan Africa is low-fertility soils with poor nitrogen (N)-supplying capacity. Many challenges in this region need to be overcome to create a viable fertilizer ...
Genome-wide association study to identify genomic regions influencing spontaneous fertility in maize haploids
Efficient production and use of doubled haploid lines can greatly accelerate genetic gains in maize breeding programs. One of the critical steps in standard doubled haploid line production is doubling the haploid genome ...
An integrated approach to maintaining cereal productivity under climate change
Wheat, rice, maize, pearl millet, and sorghum provide over half of the world's food calories. To maintain global food security, with the added challenge of climate change, there is an increasing need to exploit existing ...
Combining ability and testcross performance of drought-tolerant maize inbred lines under stress and non-stress environments in Kenya
(Blackwell Verlag, 2017)
Drought and poor soil fertility are among the major abiotic stresses affecting maize productivity in sub-Saharan Africa. Maize breeding efforts at the International Maize and Wheat Improvement Center (CIMMYT) have focused ...
A novel remote sensing approach for prediction of maize yield under different conditions of nitrogen fertilization
Maize crop production is constrained worldwide by nitrogen (N) availability and particularly in poor tropical and subtropical soils. The development of affordable high-throughput crop monitoring and phenotyping techniques ...
Genetic analysis of tropical maize inbred lines for resistance to maize lethal necrosis disease
Maize lethal necrosis (MLN) disease is a recent outbreak in eastern Africa and has emerged as a significant threat to maize production in the region. The disease is caused by the co-infection of Maize chlorotic mottle virus ...
Genetic gains in CIMMYT maize breeding program in Africa
Lagarta do funil do milho em África: um guia para o manejo integrado de pragas
O mundo tem visto progressos significativos na luta contra a fome, a desnutrição e a extrema pobreza, embora ainda haja muito a fazer. Ao mesmo tempo, o surgimento e a rápida dispersão da lagarta do cartucho do milho (LCM; ...
