Interpretive Summary: Potatoes come in different varieties with each having characteristics that make them suitable for different processes such as fresh market, or chipping. New potato varieties that are resistant to pests and that can serve as chipping potatoes are in demand. Lehigh is a new potato cultivar with yellow flesh and netted skin that was released by the New York Agricultural Experiment Station in 2007. Lehigh is currently grown primarily for the fresh market but may serve as a promising chipping cultivar. Lehigh is resistant to common scab, a soilborne disease caused by a bacterium-like pathogen, as well as to the golden nematode (GN), a quarantine pest currently present in New York. Lehigh is widely adapted in potato growing areas, which may help prevent GN from establishing in new areas in the U.S.

Technical Abstract: Lehigh is a widely adapted yellow-fleshed potato cultivar with excellent yield and resistance to both common scab and race Ro1 of the golden cyst nematode (Globodera rostochiensis). It was selected from a cross made at Cornell University in 1994 between the fresh market cultivar Keuka Gold and the chipping cultivar Pike and released by the New York Agricultural Experiment Station in 2007. The tubers are oval and slightly flattened, with shallow eyes and netted skin. Although currently grown primarily for the fresh market, the fry color of Lehigh is comparable in lightness to the chipping cultivar Snowden when chipped out of 10C storage in December. Lehigh specific gravity averaged 1.080 across 60 Northeastern US trials, while marketable yield averaged 111% of Atlantic across 80 trials in New York, Pennsylvania and Maine.
