Combining ability and testcross performance of drought-tolerant maize inbred lines under stress and non-stress environments in Kenya
(Blackwell Science Ltd, 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 ...
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 ...
Unmanned aerial platform‑based multi‑spectral imaging for field phenotyping of maize
(BioMed Central, 2015)
Background: Recent developments in unmanned aerial platforms (UAP) have provided research opportunities in assessing land allocation and crop physiological traits, including response to abiotic and biotic stresses. UAP-based ...
Maize production in a changing climate: Impacts, adaptation, and mitigation strategies
Plant breeding and improved management options have made remarkable progress in increasing crop yields during the past century. However, climate change projections suggest that large yield losses will be occurring in many ...
Discovery and validation of genomic regions associated with resistance to maize lethal necrosis in four biparental populations
In sub-Saharan Africa, maize is the key determinant of food security for smallholder farmers. The sudden outbreak of maize lethal necrosis (MLN) disease is seriously threatening the maize production in the region. Understanding ...
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 ...
MLN pathogen diagnosis, MLN-free seed production and safe exchange to non-endemic countries
Maize Lethal Necrosis (MLN) is a viral disease caused by a synergistic interaction of Maize Chlorotic Mottle Virus (MCMV) and Sugarcane Mosaic Virus (SCMV) or other viruses such as Maize Dwarf Mosaic Virus (MDMV) or Wheat ...
