ORIGIN: Castile was released by the USDA and the New York State Agriculture Experiment Station in 1991. It was selected from the progeny of a cross between Peconic and F107-30 and was tested as B7592-1.

CHARACTERISTICS: The vine maturity of Castile is main season. Plants are medium to large, initially upright and later spreading and dense. Stems are green with slight purple pigmentation mostly at the nodes. Wings are prominent, straight to slightly waved. Leaves are medium to dark green with four pairs of primary leaflets. Flowers are violet with white tips. Tubers are oblong, slightly flattened with shallow eyes. Skin is smooth and white. Tubers are suitable for tablestock, chip and French fry processing. Yield potential is good and specific gravity is considered in the medium range.

STRENGTHS & WEAKNESSES: The good yielding ability and market flexibility are the primary advantages. Tubers of this clone are generally free of internal defects. The good internal quality coupled with resistance to Race A of the golden nematode (GN) make this variety well suited to regions where GN resistance is needed and where internal necrosis can occur. Moisture stress can result in lower yields and irregular shaped tubers. Tubers are susceptible to early blight.
