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 ...

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 ...

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 ...

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 ...
