Project Type: Specific Cooperative Agreement

Start Date: Aug 15, 2003
End Date: May 31, 2008

Objective:
The objectives of this research are (1) to conduct multi-location field trials to expedite the commercialization of new multiple stress tolerant corn hybrids that are not currently available in Texas and other Southern states, and (2) develop extension publications for using these hybrids.

Approach:
Corn hybrids developed by the Texas Agricultural Experiment Sation and other widely grown hybrids will be grown at seven locations in Texas and Mississippi under different degrees of drought stress. At some locations the hybrids will be inoculated with Aspergillus flavus. Data will be recorded on flowering date, plant height, lodging, and other agronomic traits. Mature ears will be hand harvested and rated for ear molds and insect damage. Grain will be analyzed for aflatoxin contamination. The proposed research will help to identify multiple stress resistant corn and provide the germplasm and information needed by the seed industry to develop and commercialize hybrids with resistance to aflatoxin contamination.
