Harnessing native genetic variation for resistance to field and storage insects pests in tropical maize

The stem borer ( Chilo partellus Swinhoe) causes 12%–17% yield losses in the field, while additional 15%–30% grain losses are caused by the maize weevil ( Sitophilus zeamais Motschulsky) in storage across sub-Saharan Africa. Despite advances in host plant resistance, maize hybrids with combined resistance to both...

Multi-trait selection of tropical maize hybrids for combined productivity, agronomic stability, and aflatoxin resistance

Aspergillus ear rot (ear rot) and aflatoxin contamination, caused mainly by Aspergillus flavus , threaten maize productivity, grain quality, and food safety in tropical and sub-tropical regions. Although significant breeding progress has been made, selection for resistance remains challenging due to environmental c...
