CIMMYT Maize Program, strategic plan: 1995 and beyond
Winter wheat genotypes under different levels of nitrogen and water stress: Changes in grain protein compositionQuantification of Bt Delta-endotoxins in leaf tissues of tropical Bt maize populations
Hard white winter wheat with superior and consistent quality is preferable for Asian markets. This study investigated the combined influences of moisture deficit during grain-fill and N management on protein quality, dough ...
Molecular characterization of diverse CIMMYT maize inbred lines from eastern and southern Africa using single nucleotide polymorphic markers
(BioMed Central, 2012)
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 breeding programs ...
Yield stability of stem borer resistant maize hybrids evaluated in regional trials in east Africa
Twenty-seven stem borer-resistant maize hybrids and three checks were evaluated in 14 locations in Kenya and Ethiopia to study the genotype x environment interaction (GEI) and yield stability. An analysis of variance was ...
Levels of control of Chilo partellus stem borer in segregating tropical Bt maize populations in Kenya
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 ...
Control of Busseola fusca and Chilo partellus stem borers by Bacillus thuringiensis (Bt)-d-endotoxins from Cry1Ab gene Event MON810 in greenhouse containment trials
Previous testing of several public Bacillus thuringiensis (Bt)-maize events did not show control of the African stem borer (Busseola fusca Fuller), an important stem borer species, without which stewardship would be ...
Developmental and mortality responses of Chilo partellus Swinhoe (Lepidoptera: Crambidae) and Sesamia calamistis Hampson (Lepidoptera: Noctuidae) following partial feeding on Bt-transgenic maize
Objective: To determine i) the susceptibility of different instars of Chilo partellus Swinhoe (Lepidoptera: Crambidae) and Sesamia calamistis Hampson (Lepidoptera: Noctuidae) to Bt maize (expressing Cry1Ab) and ii) the ...
Experiences in effective communication on transgenic technology in Africa - the case of the insect resistant maize for Africa (IRMA) project
The Insect Resistant Maize for Africa (IRMA) Project, aimed to improve food security through developing and deploying locally adapted stem borer resistant maize varieties using both conventional and biotechnology mediated ...
Testing public Bt maize events for control of stem borers in the first confined field trials in Kenya
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 ...
