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 ...
Molecular characterization of global maize breeding germplasm based on genome-wide single nucleotide polymorphisms
Characterization of genetic diversity is of great value to assist breeders in parental line selection and breeding system design. We screened 770 maize inbred lines with 1,034 single nucleotide polymorphism (SNP) markers ...
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 ...
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 ...
Response to S1 recurrent selection for resistance to two stem borers, Busseola fusca and Chilo partellus, in two tropical maize populations
(Springer Verlag, 2015)
Stem borers, Busseola fusca and Chilo partellus, are among the key devastating lepidopteran insect pests ofmaize causing grain yield losses.Recurrent selection studies for stem borer resistance in maize are limited. ...
Bt-transgenic maize does not deter oviposition by two important African cereal stem borers, Chilo partellus Swinhoe (Lepidoptera: Crambidae) and Sesamia calamistis Hampson (Lepidoptera: Noctuidae)
Objective: To assess Chilo partellus Swinhoe (Lepidoptera: Crambidae) and Sesamia calamistis Hampson (Lepidoptera: Noctuidae) ovipositional responses on Bt (Event 216, containing the Cry1Ab gene) and isogenic non-Bt (CML ...
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
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 ...
Identification of new maize inbred lines with resistance to Striga hermonthica (Del.) Benth
Striga hermonthica is a noxious, obligate hemi-parasite of cereal grasses that causes severe grain yield loss in susceptible maize cultivars in Africa. The development of host plant resistance is one of the most practical ...
