Sub-Saharan African maize-based foods: technological perspectives to increase the food and nutrition security impacts of maize breeding programmes
The demand for maize in Sub-Saharan Africa will triple by 2050 due to rapid population growth, while challenges from climate change will threaten agricultural productivity. Most maize breeding programmes have focused on ...
Molecular genetic diversity and population structure of Ethiopian white lupin landraces: implications for breeding and conservation
(Public Library of Science, 2017)
White lupin is one of the four economically important species of the Lupinus genus and is an important grain legume in the Ethiopian farming system. However, there has been limited research effort to characterize the ...
Plant breeding can be made more efficient by having fewer, better crosses
(BioMed Central, 2013)
Background: Crop yields have to increase to provide food security for the world?s growing population. To achieve these yield increases there will have to be a significant contribution from genetic gains made by conventional ...
Rapid breeding and varietal replacement are critical to adaptation of cropping systems in the developing world to climate change
Plant breeding is a key mechanism for adaptation of cropping systems to climate change. Much discussion of breeding for climate change focuses on genes with large effects on heat and drought tolerance, but phenology and ...
An update of recent use of Aegilops species in wheat breeding
Aegilops species have significantly contributed to wheat breeding despite the difficulties involved in the handling of wild species, such as crossability and incompatibility. A number of biotic resistance genes have been ...
Use of IPM in the control of multiple diseases in maize: strategies for selection of host resistance
(African Crop Science Society, 2003)
Maize (Zea mays) production in sub-Saharan Africa is constantly threatened by the potential outbreak of multiple foliar diseases such as maize streak, northern leaf blight, gray leaf spot, and rust. Improvement of host ...
Large-scale evaluation of maize germplasm for low-phosphorus tolerance
(Public Library of Science, 2015)
Low-phosphorus (LP) stress is a global problem for maize production and has been exacerbated by breeding activities that have reduced the genetic diversity of maize. Although LP tolerance in maize has been previously ...
New deep learning genomic-based prediction model for multiple traits with binary, ordinal, and continuous phenotypes
(Genetics Society of America, 2019)
Multiple-trait experiments with mixed phenotypes (binary, ordinal and continuous) are not rare in animal and plant breeding programs. However, there is a lack of statistical models that can exploit the correlation between ...
A direct comparison of remote sensing approaches for high-throughput phenotyping in plant breeding
Remote sensing (RS) of plant canopies permits non-intrusive, high-throughput monitoring of plant physiological characteristics. This study compared three RS approaches using a low flying UAV (unmanned aerial vehicle), with ...
