In the present study, 192 Ethiopian wheat accessions comprising 167 landraces 25 cultivars were genotyped with a high-density Illumina iSelect 90K single-nucleotide polymorphism (SNP) array to conduct genome-wide association analysis grain width (GW), length (GL), CIE (Commission Internationale...
Abstract Ethiopia is the largest wheat producer in sub-Saharan Africa yet remains a net importer. Increasing domestic production national priority. Improved varieties provide an important pathway to enhancing productivity and stability of production. Reliably tracking varietal use dynamics challenge, value conventional recall surveys increasingly questioned.

Agronomic quality traits, including days heading, maturity, plant height, grain yield, hectoliter weight, thousand kernel disease resistance (stem rust),...
Crops are variously susceptible to biotic stresses-something expected increase under climate change. In the case of staple crops, this potentially undermines household and national food security. We examine recent wheat rust epidemics smallholders' coping mechanisms in Ethiopia as a study. Wheat is major crop widely grown by smallholders. 2010/11 yellow epidemic affected over one-third area. Two waves nationally representative level panel data collected for preceding season (2009/10) three...
Accurate identification of crop varieties grown by farmers is crucial, among others, for management, food security and varietal development dissemination purposes. One may expect to be more challenging in the context developing countries where literacy education are limited informal seed systems recycling common. This paper evaluates extent which smallholder misidentify their wheat Ethiopia explores associated factors implications. The study uses data from a nationally representative growing...
Wheat stem rust, caused by Puccinia graminis f. sp. tritici, can cause severe yield losses on susceptible wheat varieties and cultivars. Although rust be controlled the use of genetic resistance, population dynamics P. tritici frequently lead to defeat resistance genes. race TKTTF a epidemic in Ethiopia Ug99-resistant ‘Digalu’ 2013 2014. The gene Sr11 confers is present ‘Gabo 56’. We identified seven single-nucleotide polymorphism (SNP) markers linked from cross between Gabo 56 ‘Chinese...
Septoria tritici blotch, caused by the fungus Zymoseptoria titici , poses serious and persistent challenges to wheat cultivation in Ethiopia worldwide. Deploying resistant cultivars is a major component of controlling septoria blotch (STB). Thus, objective this study was elucidate genomic architecture STB resistance an association panel 178 bread genotypes. The phenotyped for resistance, phenology, yield, yield-related traits three locations 2 years. also genotyped single nucleotide...
In Ethiopia, breeding rust resistant wheat cultivars is a priority for production. A stem epidemic during 2013 to 2014 on previously cultivar Digalu highlighted the need determine effectiveness of lines multiple races Puccinia graminis f. sp. tritici in Ethiopia. During and 2015, we evaluated total 97 bread 14 durum genotypes against four P. at seedling stage single-race field nurseries. Resistance genes were postulated using molecular marker assays. Bread race JRCQC, most virulent wheat....
Tempered radicals are change agents who experience the dominant culture as a violation of integrity and authenticity their personal values beliefs. They seek to move forward whilst challenging status quo. Does concept provide useful analytic lens through which strategies women men farmer innovators, 'doing things differently' in agriculture, can be interpreted? What for turning ambivalence tension advantage? The paper uses research data derived from two wheat-growing communities Oromia...
Nitrogen (N) use efficiency is important for wheat grain yield and quality. This study evaluated6 durum genotypes in Ethiopia to determine the extent of nitrogen (NUE) components genotype-by-environment interactions under high low N supply. The results showed that there was significant variation among NUE components. Grain ranged from 3.30 6.22 t ha−1 2.30 3.78 conditions with an average reduction 40.1%. harvest index, uptake (NUpE), utilization (NUtE) increased compared N. NUtE varied 28.6...
Abstract Many of the major stem rust resistance genes deployed in commercial wheat ( Triticum spp.) cultivars and breeding lines become ineffective over time because continuous emergence virulent races. A genome‐wide association study (GWAS) was conducted using 26,439 single nucleotide polymorphism (SNP) markers 280 durum [ turgidum L. subsp. Durum (Desf.)
