Sixth Stakeholders Meeting: Insect Resistant Maize for Africa (IRMA II) Project
(KARI; CIMMYT, 2006)
Evaluation of traits of resistance to postharvest insect pests in tropical maize
The maize weevil Sitophilus zeamais (Motschulsky) is among the most grain damaging insect in sub-saharan Africa. The objective of the study was to determine differences in traits associated with resistance to the maize ...
Responses of tropical maize landraces to damage by Chilo partellus stem borer
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 ...
Resistance of three-way cross experimental maize hybrids to post-harvest insect pests, the larger grain borer (Prostephanus truncatus) and maize weevil (Sitophilus zeamais)
The larger grain borer Prostephanus truncatus Horn and the maize weevil Sitophilus zeamais Motschulsky are important pests of stored maize in the tropics, particularly where maize is stored on-farm with little control of ...
Winter wheat genotypes under different levels of nitrogen and water stress: Changes in grain protein compositionQuantification of Bt Delta-endotoxins in leaf tissues of tropical Bt maize populations
Hard white winter wheat with superior and consistent quality is preferable for Asian markets. This study investigated the combined influences of moisture deficit during grain-fill and N management on protein quality, dough ...
Combining ability among twenty insect resistant maize inbred lines resistant to Chilo partellus and Busseola fusca Stem borers
A partial diallel design was used among 20 maize inbred lines to form 110 F1 hybrids to generate information on the values of these lines for developing insect resistant maize varieties during the short rains season of ...
Large-scale screening for maize drought resistance using multiple selection criteria evaluated under water-stressed and well-watered environments
A total of 550 maize inbred lines collected from global breeding programs were evaluated for drought resistance under both well-watered and water-stressed environments. The evaluation was based on multiple measurements of ...
Participatory farmer evaluation of stem borer tolerant maize varieties in three maize growing ecologies of Kenya
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 ...
