My program will plan, coordinate and administer national PVY field trials of potato breeding clones and varieties from USA potato breeding programs. What level of PVY strain susceptibility exists in potato germplasm currently being used in potato breeding programs in the USA? We need to characterize this to identify PVY resistant germplasm in our state and national breeding programs. Tests conducted in Idaho, New York, and Wisconsin, against PVY strains native to each area, will examine symptom expression on plants and tubers, tuber necrotic ringspot symptoms, and PVY strain susceptibility or resistance. I will summarize results for publications for the potato industry and for potato breeding programs.
