Interpretive Summary: Lamoka is a new potato variety with white skin and white flesh that was released by the New York State Agricultural Experiment Station in 2011. Lamoka is notable for excellent chip color from cold storage and good yield and is resistant to both common scab, a soilborne disease caused by a bacterium-like pathogen, as well as the golden potato cyst nematode, a quarantine pest present in New York. This new variety has been widely adopted will help to ensure that the golden potato cyst nematode does not spread further.

Technical Abstract: Lamoka is a white-skinned, white-fleshed potato cultivar variety notable for excellent chip color from cold storage, good yield, and resistance to both common scab and race Ro1 of the golden potato cyst nematode (Globodera rostochiensis). It was selected from a cross made at Cornell University in 1998 between NY120 and NY115. The tubers are oblong and slightly flattened, with shallow eyes and relatively smooth skin. Chip color out of cold storage is better than ‘Snowden’. Marketable yield has averaged 90% of Snowden across 95 trials in New York, Pennsylvania and Maine, while specific gravity has averaged 0.003 less than Snowden. Lamoka was released by the New York State Agricultural Experiment Station in 2011.
