Tobacco Breeding & Genetics


Williams Hall 4310


Current research activities are in the areas of genetics and breeding in the genusĀ Nicotiana. More specifically, research is being conducted to take advantage of biological features of these species in order to:

  • develop and study improved and novel plant breeding methodologies
  • understand the molecular basis of disease resistance in crop plants
  • perform genetics-based manipulation of plant chemistry.

Methods used in our research are very diverse and include plant transformation, DNA marker based techniques, mutagenesis, gene-editing, and conventional field-based approaches.

Our research program also manages the United States Nicotiana Germplasm Collection

and the CORESTA Series of Smokeless Tobacco Reference Products
