Research Project: Breeding Corn for Enhanced Resistance to Aflatoxin Accumulation

Location: Corn Host Plant Resistance Research

Project Number: 6064-21000-015-07-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Aug 1, 2018
End Date: Jul 31, 2023

Objective:
Cooperator will (1) identify corn germplasm with resistance to Aspergillus flavus infection and aflatoxin accumulation, and (2) develop breeding populations and germplasm lines with enhanced resistance to aflaatoxin accumulation. Germplasm lines derived from the breeding populations will be used in producing corn hybrids with resistance to aflatoxin contamination.

Approach:
Germplasm lines from various sources including the International Maze and Wheat Improvement Center (CIMMYT) will be screened for resistance. Populations developed using multiple sources of resistance will be evaluated using different techniques at multiple locations. Molecular markers will be used to enhance breeding for improved agronomic quality and enhanced resistance.
