David R. Huff
Associate Professor of Turfgrass Breeding and Genetics

Responsibilities and Interests:

As Penn State's turfgrass breeder, my program performs basic and applied genetics on a wide range of grass species including many native to North America. My lab routinely uses DNA markers, flow-cytometry, and cytology as aids to sort through the complex genomes of these grasses during the breeding process. In addition, we also use these techniques to identify genetic boundaries (either discrete or overlapping) at the level of populations for both commercial cultivars and endemic natives. In the area of crop improvement, we focus on enhancing tolerance or resistance to several biotic and abiotic stresses. For our perennial grasses these include, wear tolerance, persistence, disease, and extreme temperatures (both heat and cold). Finally, we are performing a range of genomic investigations on the reproductive biology of these grasses including such systems as apomixis and dioecy.
