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.
