The goal of my program is to conduct research to improve the productivity, quality,profitability, safety and sustainability of corn for feed, food, and industrial products.

Specific objectives are:
1. Understand the genetic basis for tolerance and resistance to biotic (mycotoxins) and abiotic stresses (drought) and to develop maize lines and populations with resistance and/or tolerance.

2. Develop maize inbreds and populations with improved quality and processing properties for foods, feeds and industrial products. Value-enhanced corn with particular quality characteristics for end-users will add value to Texas and U.S. corn.

3. Develop lines, hybrids and populations of Quality Protein Maize, a hard endosperm highlysine corn, with excellent food and feed quality, improved nutritional properties and competitive yield.

4. Introduce and introgress exotic material to increase the genetic base of germplasm used by maize breeding programs. Exotic germplasm is a genetic resource that may contribute alleles for grain yield, disease and pest resistance, tolerance to abiotic stresses, and value-adding traits to temperate corn.

5. Apply molecular techniques to study the genetics and to facilitate the selection of economical important traits in corn. We want to integrate molecular techniques into plant breeding to increase efficiency, accuracy, and facilitate new methods in corn improvement.
