Research Project: Breeding Corn for Resistance to Aspergillus Flavus Infection and Aflatoxin Accumulation

Location: Corn Host Plant Resistance Research

Project Number: 6064-21000-013-10
Project Type: Specific Cooperative Agreement

Start Date: May 01, 2010
End Date: Apr 30, 2015

Objective:
To identify corn germplasm with resistance to Aspergillus flavus infection and aflatoxin accumulation and to identify genes associated with resistance.

Approach:
A panel of 300 corn inbred lines have been crossed with a common tester line. The resulting testcrosses will be evaluated for aflatoxin accumulation at locations in Texas and Mississippi. An association mapping analysis of genotypic and phenotypic data will be conducted to identify alleles associated with resistance to Aspergillus flavus infection and aflatoxin accumulation.
