ORIGIN: Allegany was released by the New York State Experiment Station in 1990. It was selected from a cross between M297-17, a golden nematode (GN) resistant parent, and a bulk collection of pollen from GN susceptible clones. It was tested as NY72.

CHARACTERISTICS: The vine maturity of Allegany is very late. When grown to full maturity, its yield potential is very high. It is primarily grown as a tablestock variety but can be used for chip processing in certain production areas.

Initial plant growth is slow with an open, upright appearance. The vines then develop a dense, vigorous canopy. Tuber initiation occurs late in the growing season. Tubers are round in overall shape and in cross section with shallow lateral eyes and deep apical eyes. Skin color is buff and skin texture ranges from smooth to slightly netted depending on soils and environment.

STRENGTHS & WEAKNESSES: The high yielding ability in fall production areas is this variety’s primary advantage. Allegany is not adapted to summer and winter production regions due to its late maturity. The variety has resistance to golden nematode, early blight, and Verticillium wilt and is moderately resistant to pitted scab and has some general resistance to late blight. Tubers can be marketed as tablestock and chip stock. The long dormancy of tubers is an advantage in storage. Tubers tend to be susceptible to bruising when grown at high nitrogen levels and/or when harvested in cold conditions.
