Doing development-oriented agronomy: rethinking methods, concepts and direction
(Cambridge University Press, 2019)
This special issue brings together a selection of papers that not merely present agronomic research findings, but critically review orientations, methodologies and research practices in agronomy. The focus is on agronomic ...

Genotype x environment interaction of quality protein maize hybrids under contrasting management condition in Eastern and Southern Africa
(Crop Science Society of America (CSSA), 2019)
Drought and low soil fertility are major abiotic stresses limiting yield of maize (Zea mays L.) in eastern and southern Africa. The present study was undertaken to determine genotype by environment interaction (GEI) and ...

Application of remote sensing for phenotyping tar spot complex resistance in maize
(Frontiers, 2019)
Tar spot complex (TSC), caused by at least two fungal pathogens, Phyllachora maydis and Monographella maydis, is one of the major foliar diseases of maize in Central and South America. P. maydis was also detected in the ...

Genetics of greenbug resistance in synthetic hexaploid wheat derived germplasm
(Frontiers, 2019)
The greenbug, Schizaphis graminum Rondani, significantly reduces wheat, Triticum aestivum L., grain yields if not controlled. Host plant resistance (HPR) can protect yield, is environmentally friendly and easy to use. Our ...

An R Package for Bayesian analysis of multi-environment and multi-trait multi-environment data for genome-based prediction
(Genetics Society of America, 2019)
Evidence that genomic selection (GS) is a technology that is revolutionizing plant breeding continues to grow. However, it is very well documented that its success strongly depends on statistical models, which are used by ...

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 ...

Genetic mapping reveals large-effect QTL for anther extrusion in CIMMYT spring wheat
(MDPI, 2019)
Hybrid breeding facilitates the exploitation of heterosis and it can result in significant genetic gains and increased crop yields. Inefficient cross-pollination is a major limiting factor that hampers hybrid wheat seed ...

Impact of adoption of drought-tolerant maize varieties on total maize production in south Eastern Zimbabwe
(Taylor & Francis, 2019)
Drought is a huge limiting factor in maize production, mainly in the rain-fed agriculture of sub-Saharan Africa. In response to this threat, drought-tolerant (DT) maize varieties have been developed with an aim to ensure ...
Article
Who is quitting? An analysis of the dis-adoption of climate smart sorghum varieties in Tanzania
(Emerald Publishing Limited, 2019)
Purpose: New agricultural technologies are continuously generated and promoted for adoption by farmers with the expectation that they bring about higher benefits than older technologies. Yet, depending on the perceived ...

An update of recent use of Aegilops species in wheat breeding
(Frontiers, 2019)
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 ...
