Diagnostic research is important in helping to create an enabling environment for promising biotechnology products in smallholder agriculture, before rather than after release. The biotechnology products that now hold ...

Eight promising bread wheat lines and one standard check cultivars were evaluated for grain yield performance, stability and adaptation across nine environments of the central highlands of Ethiopia. Results of the combined ...

Competitive interactions of four spring bread wheat cultivars ( Triticum aestivum check for this species in other resources L.) with four wild oat ( Avena fatua check for this species in other resources L.) seedling densities ...

Quality protein maize (QPM) describes a range of maize cultivars with twice the content of limiting amino acids lysine and tryptophan compared with conventional maize, and has been developed to help reduce human malnutrition ...

Two widely-used open pollinated maize (Zea mays L.) cultivars from East Africa, Katumani and Kito composites, developed and improved for early maturity, grain yield and drought escape were evaluated for drought tolerance ...

Cropping systems in the Ethiopian highlands involve rotations of cereals with grain legume and oilseed crops; the proportional allocation among crop species varies with altitude, rainfall, and soil type. Barley (Hordeum ...

Background: Knowledge of germplasm diversity and relationships among elite breeding materials is fundamentally important in crop improvement. We genotyped 450 maize inbred lines developed and/or widely used by CIMMYT ...

Transgenic maize (Zea mays L), developed using modified genes from the bacterium Bacillus thuringiensis (Bt), controls stem borers without observable negative effects to humans, livestock or the environment, and is now ...

In a maize breeding program, potential genotypes are usually evaluated in different environments before desirable ones are selected. Genotype x environment (G x E) interaction is associated with the differential performance ...

In Kenya, stem borers destroy an estimated 400,000 metric tons, or 13.5%, of farmers' annual maize harvest costing about US$80 millions. Bacillus thuringiensis (Bt) maize controls stem borers without harming humans, livestock ...
