David M. Spooner: Potato Germplasm Systematics
Investigate the species boundaries and phylogenetic relationships of the
tuber-bearing Solanum species (Solanum sect. Petota) using comparative
morphology, crossing studies, and RFLP analysis of DNA (60%). Collect wild
germplasm of these species in the United States, Mexico, Central and South
America (20%), and maintain a herbarium of the IR-1 potato collections
at Sturgeon Bay, WI (20%).
