Research Project: Use of Gem Germplasm for Evaluation and Development of Drought Tolerance, Corn Earworm (Cew) Resistance, and Low Aflatoxin Level Grain Corn

Location: North Central Regional Plant Introduction Station, Ames, Iowa

Project Number: 5030-21000-050-15
Project Type: Specific Cooperative Agreement

Start Date: Jul 17, 2009
End Date: Apr 30, 2013

Evaluate GEM breeding crosses and develop germplasm for abiotic (drought and heat) and biotic stress (CEW and aflatoxin) tolerance; select, advance and release inbred lines from breeding crosses containing GEM germplasm.

GEM germplasm will be evaluated for abiotic and biotic stress tolerance under controlled irrigation management. Top crosses will be made with the most tolerant inbreds and yield trials conducted. Evaluation will be conducted for CEW, and aflatoxin level, and the most resistant sources advanced by inbreeding. New exotic breeding crosses will be evaluated to identify and prioritize for future breeding under abiotic and biotic stress conditions.
