Combining ability of maize inbred lines resistant to Chilo partellus (Swinhoe) in the mid-altitude environment of Kenya
Gene action conditioning important traits in maize is useful to breeders in order to design appropriate breeding methods. A study was conducted to determine the combining ability of 10 maize inbred lines adapted to Kenya?s ...
Quality protein maize for the feed industry in Kenya
Quality protein maize (QPM) has increased levels of lysine and tryptophan, limiting amino acids for monogastric animals, so its use in animal feed reduces the need for more expensive high-protein sources. The authors, ...
Herbicide applied to Imidazolinone resistant-maize seed as a Striga control option for small-scale African farmers
Striga is a major constraint to food production in Africa. Most technologies developed for the eradication of Striga asiatica from the United States are not adaptable to Africa. Imazapyr and pyrithiobac coated imidazolin ...
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 ...
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 ...
Combining ability of maize (Zea mays L.) inbred lines resistant to stem borers
Ten inbred parents with varying resistance levels to Chilo partellus and Busseola fusca were crossed in a half diallel mating scheme to generate 45 F1 hybrids. The hybrids and five commercial checks were evaluated across ...
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 ...
