Testcross performance of doubled haploid maize lines derived from tropical adapted backcross populations
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2011)
Doubled haploid (DH) lines produced by in vivo induction of maternal haploids are routinely used in maize breeding. The present study was carried out to assess the performance of 75 doubled haploid maize testcrosses and ...

Responses of tropical maize landraces to damage by Chilo partellus stem borer
(Academic Journals, 2013)
The potential to manage insect pests using host-plant resistance exists, but has not been exploited adequately. The objective of this study was to determine the resistance of 75 tropical maize landraces through artificial ...

Quality of field collected and laboratory reared Chilo partellus (Swinhoe) (Lepidoptera: Crambidae) for screening maize genotypes
(Academic Journals, 2013)
The quality of laboratory reared stem borer species for screening of maize varieties is usually questioned by end user cereal breeders. A quality check study was performed in a screen house at KARI-Katumani to evaluate the ...

Evaluation of stem borer resistance management strategies for Bt maize in Kenya based on alternative host refugia
(Academic Journals, 2011)
Stem borers are the major insect pests of maize in Kenya. The use of Bacillus thuringiensis (Bt) technology is an effective way of controlling lepidopteran pests. However, the likelihood of development of resistance to ...

Combining ability of maize (Zea mays L.) inbred lines resistant to stem borers
(Academic Journals, 2011)
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 ...
Article
Genotype by environment interactions and yield stability of stem borer resistant maize hybrids in Kenya
(Academic Journals, 2011)
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 ...
Article
Grain yield, stem borer and disease resistance of new maize hybrids in Kenya
(Academic Journals, 2011)
Evaluation of 30 maize hybrids for yield and resistance to stem borers and foliar diseases in four agro-ecologies in Kenya was conducted in 2009. There were significant differences among the hybrids in leaf damage, number ...

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 ...
