Dr. Seth C. Murray joined Texas A&M University in 2008 as an Assistant Professor in the Department of Soil and Crop Sciences where he directs a program that focuses on both quantitative genetic discovery and applied maize breeding. Important traits in his program include improved aflatoxin resistance, drought tolerance, nutrient use efficiency in yellow corn for Texas and the Southern US and the incorporation of novel genetic diversity for perennial corn and blue corn. He has developed statistical techniques for improved genetic mapping of natural variation and to increase understanding of plant genomes. Dr. Murray received a BS in Crop and Soil Sciences at Michigan State University in 2001 where he worked in a sugar-beet genomics lab and co-founded a student organic farm. He received his PhD at Cornell University in 2008 in the Department of Plant Breeding and Genetics where he identified regions of the genome (QTL) conditioning energy accumulation and carbohydrate partitioning in sweet and grain sorghums. Currently he is an Associate Editor for Crop Science, Associate Editor for the Journal of Plant Registrations (maize), is on the Executive Committee of the National Association of Plant Breeders, and serves as chair or vice-chair for a number of regional and national scientific meetings. He has/is a committee member for 29 graduate students including 12 as a chair, teaches a graduate level class in “Molecular Quantitative Genetics in Plant Breeding” to PhD students and co-teaches additional classes at the graduate and undergraduate level. Dr. Murray has been an author or co-author on 23 peer reviewed articles, and the PI/co-PI of numerous federal, state, and commodity research grants.

My research focuses molecular quantitative genetics as well as applied maize breeding. Identifying and quantifying genetic effects in maize for tolerance and resistance to biotic and abiotic stresses, most importantly Aspergillus flavus / aflatoxin resistance and drought and heat tolerance. Introgression of exotic (subtropical, tropical, wild) germplasm into adapted subtropical and temperate germplasm. Development of germplasm with improved grain quality (antioxidents) and processing properties or value-added traits. Development of quantitative genetic models, theories and approaches. QTL mapping for traits of interest using linkage, association, or selection mapping methods and/ or genomic selection. My end goal is to increase the economic and environmental sustainability of agricultural production.
My teaching is primarily focused on graduate student training at the M.S. and Ph.D. levels and is closely integrated with my research program. My classroom teaching includes a class for Ph.D. plant breeding students and genetics students, SCSC 643 “Molecular Quantitative Genetics in Plant Breeding” taught every spring. I teach the graduate seminar SCSC 681 for students to present their research every semester. I will also be teaching the undergraduate writing intensive class SCSC 481 “Senior Seminar” in Fall semesters.
