Models for predicting losses can extend to other pest species and maize growing ecologies. NARSs will promote germplasm with such traits. Grain will be acceptable for food preparation. Purpose Indicators Assumptions and risks To develop source germplasm from which the biochemical and genetic basis for resistance mechanisms can be defined and then exploited within the context of traditional and marker-assisted breeding programs. Biochemical resistance mechanisms extend across a wide range of accessions, varieties, and lines.
Molecular tools are sufficiently advanced for monitoring quantitative grain quality traits.
Outputs Indicators Assumptions and risks 1. Maize lines resistant to Prostephanus truncatus and Sitophilus zeamais with high nutritional value and processing qualities for tropical ecologies. Stress tolerant, high yielding germplasm with improved resistance to storage pests. Technical report on breeding methodologies for developing maize varieties with improved resistance to post-harvest pests and diseases. On-farm testing and training of farmers and NGOs to improve dissemination of resistant germplasm.
