Specialty´╝ÜPlant Breeding, Genetics, Molecular & Environmental Plant Sciences

I hold a joint appointment with Texas A&M University and Texas A&M AgriLife Research. I am a professor in the Department of Soil and Crop Sciences, with over 40 years of experience in breeding of diploid and polyploid crops, germplasm introgression, reproductive biology and cytology, cytogenetics, genetics, and genomics.


My breeding and scientific research, graduate and post-graduate programs relate directly or indirectly to use of naturally occurring germplasm for crop improvement. Elements of the research include wild-species germplasm introgression, chromosome substitution, reproductive and ploidy manipulations, conventional cytogenetics and fluorescence in situ hybridization, genetic analysis, marker development (SSRs, SNPs), marker assisted selection, reproductive cytology and genetics, and various types of genome mapping (linkage, BAC physical, and radiation hybrid), sequencing, and their integration for genome sequencing and assembly. Most of my research aims to enhance the germplasm, knowledge, science and technologies for genetic improvement Upland cotton, e.g., economic yield and sustainability; some, however, is devoted to sorghum, especially wide hybridization and germplasm utilization.
