Participatory farmer evaluation of stem borer tolerant maize varieties in three maize growing ecologies of Kenya
(Academic Journals, 2011)
Insect resistant maize for Africa (IRMA) project aims at developing and deploying insect resistant maize varieties to reduce grain losses due to insect pests. As part of incorporating farmers? perceptions to improve the ...

Effects of insect population density and storage time on grain damage and weight loss in maize due to the maize weevil Sitophilus zeamais and the larger grain borer Prostephanus truncatus
(Academic Journals, 2011)
In the period 2007 to 2010, at localities Backi Maglic and Krivaja studies of weed seedbank were performed under soybean crop. Results showed that weed seed separated at Backi Maglic in all years dominated in the top soil ...

Resistance of Bt-maize (MON810) against the stem borers Busseola fusca (Fuller) and Chilo partellus (Swinhoe) and its yield performance in Kenya
(Elsevier, 2016)
A study was conducted to assess the performance of maize hybrids with Bt event MON810 (Bt-hybrids) against the maize stem borer Busseola fusca (Fuller) in a biosafety greenhouse (BGH) and against the spotted stem borer ...

Agronomic performance and genotype X environment interaction of herbicide-resistant maize varieties in eastern Africa
(Crop Science Society of America (CSSA), 2015)
Striga hermonthica (Del.) Benth. and Striga asiatica (L.) Kuntze severely affect maize (Zea mays L.) production in sub-Saharan Africa. A single Striga plant produces a large number of seeds that form a bank of viable but ...

Maize combined insect resistance genomic regions and their co-localization with cell wall constituents revealed by tissue-specific QTL meta-analyses
(Frontiers, 2018)
Combinatorial insect attacks on maize leaves, stems, and kernels cause significant yield losses and mycotoxin contaminations. Several small effect quantitative trait loci (QTL) control maize resistance to stem borers and ...

Improving maize grain yield under drought stress and non-stress environments in Sub-Saharan Africa using marker-assisted recurrent selection
(Crop Science Society of America (CSSA), 2016)
In marker-assisted recurrent selection (MARS), a subset of molecular markers significantly associated with target traits of interest are used to predict the breeding value of individual plants, followed by rapid recombination ...

Sources of resistance to the maize weevil Sitophilus Zeamais in tropical maize
(Canadian Center of Science and Education, 2012)
The maize weevil, Sitophilus zeamais (Motschulsky) (Coleoptera: Curculionidae), is among the major storage pests that enhance food insecurity among maize farmers. New sources of resistance to the maize weevil are critical ...
