Abstract
Saginaw Gold is a pale yellow fleshed potato cultivar bred at Michigan State University and selected in Ontario, Canada for consistently producing high quality potato chips and french fries after storage. Chip color of Saginaw Gold has surpassed that of standard storage chipping cultivars such as Norchip while achieving similar yields. Saginaw Gold produced the best colored chips in the Ontario Regional Trials for four consecutive years (1983–1986). French fry quality is equivalent to that of Russet Burbank and Shepody but tuber size and fry length are smaller.
Specific gravities in Ontario, have averaged between 1.078 and 1.088. Saginaw Gold rarely develops symptoms of virus diseases when grown for repeated generations under high disease pressure from potato leaf roll virus (PLRV) and potato viruses X (PVX) and Y (PVY).
Compendio
Saginaw Gold es un cultivar de papa de carne amarilla pálida, mejorada en la Universidad Estatal de Michigan y seleccionada en Ontario, Canadá, para la producción consistente de papas fritas a la inglesa y a la francesa de alta calidad después del almacenamiento. El color de las papas fritas a la inglesa de Saginaw Gold ha superado al de aquellos cultivares como Norchip utilizados con esta finalidad y que tienen un almacenamiento estándar obteniéndose también rendimientos similares. En los Ensayos Regionales de Ontario, Saginaw Gold produjo las papas fritas a la inglesa de mejor color por cuatro años consecutivos (1983–1986). La calidad de las papas fritas a la francesa es equivalente a la de Russet Burbank y Shepody, pero el tamaño del tubérculo (y el tiempo de fritura) son menores.
En Ontario, el promedio de las gravedades específicas varió de 1,078 a 1,088. Saginaw Gold rara vez desarrolla síntomas de enfermedades causadas por virus cuando se le cultiva por varias generaciones bajo una alta presión del virus del enrollamiento (PLRV) y de los virus X (PVX) yY(PVY).
