Mega-environment targeting of maize varieties using Ammi and GGE bi-plot analysis in Ethiopia
(Ethiopian Institute of Agricultural Research, 2018)
In multi-location experimental trials, test locations must be selected to properly discriminate between varieties and to be representative of the target regions. The objective of this study were to evaluate test locations ...
Maize grain stored in hermetic bags: effect of moisture and pest infestation on grain quality
(Hindawi Publishing Corporation, 2018)
Maize (Zea mays) is an important staple food crop produced by the majority of smallholder farmers that provides household food security through direct consumption and income generation. However, postharvest grain losses ...
Bionomics of the sweet potato weevil, Cylas puncticollis (Coleoptera: Brentidae) on four different sweet potato varieties in sub-Saharan Africa
(Kassel University Press, 2018)
Sweet potato (Ipomoea batatas (L.) Lam.) is an important staple food crop in sub-Saharan Africa. A limiting production factor is infestation by the sweet potato weevil Cylas puncticollis (Boheman) (Coleoptera: Brentidae). ...
Quality protein maize (QPM) for school feeding in Ethiopia: stakeholders consultation, sensory evaluation and potential impact
Recently there is an increased attention among policy and research practitioners on the link between school feeding programs (SFP) and agricultural development. Through purchases and procurement of locally produced foods, ...
Sub-Saharan african maize-based foods: processing practices, challenges and opportunities
(Taylor & Francis, 2019)
In vast swathes of Sub-Saharan Africa, maize is the staple food with consumption of up to 450 g/person/day. Additionally, maize is used as a weaning food for infants as well as for special ceremonies, caring for the sick, ...
Genetic architecture of maize chlorotic mottle virus and maize lethal necrosis through GWAS, linkage analysis and genomic prediction in tropical maize germplasm
Maize lethal necrosis (MLN) is a serious threat to the food security of maize-growing smallholders in sub-Saharan Africa. The ability of the maize chlorotic mottle virus (MCMV) to interact with other members of the Potyviridae ...
Understanding the factors influencing fall armyworm (Spodoptera frugiperda J.E. Smith) damage in African smallholder maize fields and quantifying its impact on yield. A case study in Eastern Zimbabwe
Fall armyworm (FAW, Spodoptera frugiperda J.E. Smith) is an invasive lepidopteran pest established in most of subSaharan Africa since 2016. Although the immediate reaction of governments has been to invest in chemical ...
Genome-wide association mapping and genomic prediction analyses reveal the genetic architecture of grain yield and flowering time under drought and heat stress conditions in maize
(Blackwell Verlag, 2019)
Drought stress (DS) is a major constraint to maize yield production. Heat stress (HS) alone and in combination with DS are likely to become the increasing constraints. Association mapping and genomic prediction (GP) analyses ...
Heterogeneous seed access and information exposure: implications for the adoption of drought-tolerant maize varieties in Uganda
Frequent droughts in sub-Saharan Africa imply water stress for rainfed agriculture and, ultimately, food insecurity, underlining the region’s vulnerability to climate change. Yet, in the maize-growing areas, farmers have ...
Factors affecting genomic selection revealed by empirical evidence in maize
Genomic selection (GS) as a promising molecular breeding strategy has been widely implemented and evaluated for plant breeding, because it has remarkable superiority in enhancing genetic gain, reducing breeding time and ...
