Is labour a major determinant of yield gaps in sub-Saharan Africa? a study of cereal-based production systems in Southern Ethiopia
We investigated the role of labour in explaining the yield gap of cereals at both crop and farm levels on smallholder farms in Southern Ethiopia. A household survey containing detailed information of labour use at crop and ...
Genética de la resistencia a roya amarilla causada por Puccinia striiiformis f. sp. tritici W. en tres genotipos de trigo (Triticum aestivum L.)
(Sociedad Mexicana de Fitogenética, 2019)
La roya amarilla del trigo causada por Puccinia striiformis f. sp. tritici se ha convertido en una enfermedad de importancia a nivel mundial en los últimos años. La resistencia genética en variedades es la estrategia más ...
Implication of rate and time of nitrogen application on wheat (Triticum aestivum. l .) yield and quality in Kenya
(Elewa BioSciences, 2011)
In Kenya, Nitrogen is the first limiting macro-element on many farms where bread wheat (Triticum aestivum) has been grown continuously for more than a decade. On-farm trials were conducted in Kenya by superimposing the ...
Genetic diversity analysis in Exotic germplasm accessions of Wheat (Triticum aestivum L.) by cluster analysis
The present investigation was planned to assess genetic diversity for yield, yield contributing traits and resistance to spot blotch disease of wheat in two hundred exotic germplasm accessions of bread wheat. The germplasm ...
Validation of candidate gene-based markers and identification of novel loci for thousand-grain weight in spring bread wheat
Increased thousand-grain weight (TGW) is an important breeding target for indirectly improving grain yield (GY). Fourteen reported candidate genes known to enhance TGW were evaluated in two independent and existing datasets ...
A wheat chromosome 5AL region confers seedling resistance to both tan spot and Septoria nodorum blotch in two mapping populations
Tan spot (TS) and Septoria nodorum blotch (SNB), caused by Pyrenophora tritici-repentis and Parastagonospora nodorum, respectively, are important fungal leaf-spotting diseases of wheat that cause significant losses in grain ...
Genetic variation for photosynthetic capacity and efficeincy in spring wheat
(Oxford University Press; Society for Experimental Biology, 2019)
Use of genomic selection and breeding simulation in cross prediction for improvement of yield and quality in wheat (Triticum aestivum L.)
In wheat breeding, it is a difficult task to select the most suitable parents for making crosses aimed at the improvement of both grain yield and grain quality. By quantitative genetics theory, the best cross should have ...
